Abstract
Eid al-Adha is one of the important religious festivals for Muslims in the world. Sheep traders can be divided into primary traders and opportunist traders based on trade activity in this period. This study aims to investigate the preferences of sheep traders on marketing place and their satisfaction during Eid al-Adha period in Yogyakarta, Indonesia. In-depth and semi-structured interviews with 59 sheep traders were conducted on Juli 15 – August 25, 2018. The collected data were analyzed by descriptive analysis (score, index and rank). The results indicate that the most livestock purchased from the animal market, followed from farmers for primary traders and livestock traders for opportunist traders. Livestock most widely sold to individual consumers who come to their stalls, and then sold to animal market by primary traders and to organization/groups by opportunist traders. Most primary traders (64.10%) state to sell their sheep with different prices for different types of buyers, while the majority of opportunist traders (65.00%) thought no different. The average price different is IDR 286,364 according to primary traders and IDR 150,000 according to opportunist traders. Most of the primary traders (69.23%) and opportunist traders (90.00%) was pleased with the momentum of Eid al-Adha, as the selling price of their livestock could be higher, easy to sell, and any buyer. The conclusion is that both primary and opportunist traders in Yogyakarta have similar preferences in marketing place to buy and sell their livestock during Eid al-Adha period. Eid al-Adha period provides pleasure and an additional benefit for sheep traders.

Published: November 2019

Abstract
This study aims at examining the performance of the ClO2 on treating ballast water of Dalian new port area foreign trade oil pool in the cases of different experimental parameters, and Cylindrospermopsis raciborskii (CR), Gymnodinium catenatum (GC) and Gymnodinium cf. mikimotoi (GCM) are used for this experiment. The results shows that under certain test condition, the removal rates are in proportion to the dosage of ClO2 and reaction time, and inversely proportion to pH value, humic acid and ammonia nitrogen content. Accordingly, on operating at the optimal dosage of ClO2 and parameters of experiment, this process is proven to be an effective technology to remove these three algae and organic compounds in ballast water. In ballast water, the removal ability of ClO2 for these three algae is less sensitive to pH value, humic acid and ammonia nitrogen content than to ClO2 dosage and reaction time. Removing GC, GCM and CR with ClO2 are attributed to the second order reaction. Investigating the performance of such process, could serve to develop management strategies that enable mitigating the impacts of harmful substance in ballast water and help improving and ensuring quality of ballast water.

Authors: Cao Jinhua , Liu Weiwei , Chen Yao 
Published: November 2019

Abstract
Boron nitride nanoplatelet (BNNP) reinforced gadolinia-doped ceria (GDC) electrolyte was successfully fabricated by plasma spray. Phase constitution by X-ray Diffraction revealed that ceria was the dominating phase, and Raman spectra showed that the added BNNPs retained their original structure after harsh plasma spray process. Meanwhile, microstructure observations of the as-sprayed samples indicated that the addition of BNNPs had a significant influence on the reduction of porosity. Compared to GDC electrolyte, hardness and elastic modulus of the BNNP/GDC electrolytes were improved by ∼ 15.7% and ∼ 41.6%, respectively. More importantly, fracture toughness of as-sprayed BNNP/GDC electrolyte increased by ∼45.6%. These results illustrated that BNNPs had a positive influence on the mechancial properties. BNNP pullout, crack bridging by anchored BNNPs are the dominate toughening mechanisms for GDC composites electrolyte through SEM observing the fractured surfaces and development of indentation-induced cracks.

Authors: Zhenggui Zhang , Tie Xiao , Wanbo Zhu , Haonan CHEN 
Published: November 2019

Abstract
The effect of temperature on the recrystallization texture and microstructure of non-oriented silicon steel under asymmetrical rolling condition was studied and the relationship between the magnetism property and recrystallization texture was discussed. The results show that the texture intensity is higher at the fast roller side than that at the slow roller side, but the texture component of recrystallization texture is almost the same under different annealing temperature. At 750 °C, the main texture component is y texture (<111>//normal direction), and the texture (<110>//rolling direction) components become weak. At 850 °C, the main texture components are {111}<110> and {111}<112> texture components. With further increasing of the temperature, the strength of {111}<110> and {111}<112> texture does not change, but they tend to disperse and change to {118} and {1115}, and {001} plane texture. The results also indicate that the annealing temperature has significant influence on the iron-loss, but has no obvious influence on the magnetic induction.

Abstract
An environmentally friendly chromium-free insulating coating suitable for oriented silicon steel was prepared by using aluminium dihydrogen phosphate, silica sol, water-based resin, sodium tetraborate and graphene aqueous dispersion as main raw materials. The morphology of the insulating coating was characterized by scanning electron microscopy. Corrosion resistance was investigated by neutral salt spray test and electrochemical test. Magnetic properties and surface insulating resistance were measured. The results showed that the surface of the insulating coating was flat; the addition of graphene could effectively improve the corrosion resistance and magnetic properties of the coating. The corrosion rate in the salt spray test was less than 10% after 120h, and the core loss was reduced by 9.57%. The addition of the graphene did not destroy the insulation properties of the coating. The surface insulation resistance per side of the coating was 269.51 Ω⋅mm2.

Published: November 2019

Abstract
In this paper, the Brinell hardness tester and the Leeb hardness tester are used to test the hardness of the welded joints of P92 steel under different heat treatment conditions. A new conversion relationship between Brinell hardness and Leeb hardness of the welded joints of P92 steel is obtained by data fitting. The results show that the Brinell hardness of welded joints of P92 steel obtained from the original conversion relationship of the Leeb hardness tester is lower than that of the actual ones, because the chemical composition, microstructure and strengthening mechanism of P92 steel are obviously different from those of the low-carbon steel, low-alloy steel and cast steel. The new conversion relationship can accurately characterize the hardness of P92 steel components, solve the problem of the accuracy of the existing Leeb hardness tester to characterize this kind of material, and provide an accurate basis for the welding process and metal supervision of materials for ultra-supercritical units.

Authors: Bai Lingyun , Men Dandan , Peng Wenyi , Chen Tuchun 
Published: November 2019

Abstract
Sol-gel method combined with plasma surfacing was used to prepare TiO2/Al2O3/Incone1625 composite coatings on the surface of Q235 alloys. Oxidation thermodynamic results show the composite coatings caused lower oxidation weight gain than the sample with single coating. Combination of XRD and SEM results illustrates that the surface and cross-sectional morphology were composed of an innermost continuous but not compact enough Cr2O3 layer, the outer layer next to C2O3 was loose and cracked NiO, and the outermost layer was composed of iron oxides for the Incone1625 coated sample. For the composite coating sample, the oxide film was composed of NiO as the outermost layer, Cr2O3 as the inner layer, there was a very thin but continuous layer consisted of Cr2O3 and Al2O3 as the innermost layer. This work shows that TiO2/Al2O3/Incone1625 composite coating improves the high-temperature oxidation resistance properties of the Q235 alloy at 900 °C by promoting the formation of the protective Cr2O3 and Al2O3 film.

Effect of microstructure and mechanical properties on tensile loading-unloading characteristics of cold-rolled DP780 steels
Authors: Lin Chengjiang , Tang Di 
Published: November 2019

Abstract
Tensile loading-unloading characteristic of three cold-rolled DP780 steels was studied. Similar hardening behaviour was showed by these steels even with different chemical composition and microstructures. Tensile loading-unloading tests with prestrain between 0.5% and 8% were carried out on Instron tensile testing machine. Sample microstructures were analysed by EBSD and SEM. Hardness of ferrite and martensite were measured by nanohardness instrument. Total unloading recovery strain, which is related to unloading chord modulus (Echord), can be divided into elastic strain and microplastic strain. The results showed that there was no correlation between unloading microplastic strain (εmp) and phase fraction or phase size within the scope of this study. However, with the increase of flow strength increment, εmp increases while Echord reduction becomes larger. Furthermore, εmp depends on the phase yield strength ratio between martensite phase and ferrite phase (σm/σf), emp increases as the σm/σf increase for a given flow strength increment. The results showed that the springback of DP780 steels can be improved by reducing the yield strength difference between martenstie and ferrite.
