Joint research report of JIJRec program
QIN XiaomengˈDepartment of Materials Science and Engineering City University of Hong Kong

Research Activity
I studied in Osaka Universityfunded by 2020 JIJReC grantas a visiting student from
1 January 2021 to 28 February 2021. I resided at Osaka University Kasugaoka House. I
conducted the research under the supervision of Prof. Hidetoshi FUJII, Joining and
Welding Research Institute (JWRI), Osaka University. My research work continues theline of previous work relating to alloying by friction stir processing in CoCrFeNi highentropy alloy. As a visiting student, I was also involved in the regular group meeting of
the lab.
Research Results
Our previous work demonstrated that the grain refinement induced by friction stir
welding (FSW) could greatly improve the strength of CoCrFeNi high entropy alloy. In
this study, CoCrFeNi HEA, which has a single FCC phase, was processed by FSP withadditional alumina or graphite powders. The strength of the CoCrFeNi HEA is expected
to enhance via grain refinement and second phase precipitation while maintaining
ductility because of its heterogeneous structure. The base metal (as-cast CoCrFeNi ingot)
and alloying powder (alumina and graphite powders.) were prepared in CityU. Fig. 1
shows the summary of the experimental flow graph. Fig. 2 shows the schematic of FSP
on the CoCrFeNi plate along with powders in the pre-drilled holes.

All the scheduled FSP work has been finished in JWRI, while characterization and test
work are also needed to do in the future. It mainly includes the following: (1) hardness
profiles along the cross-section of the joints and deep microstructure analysis of the Aladdition FSPed samples; (2) all the characterization and test work of carbon-addition
FSPed samples.
I would like to thank Joining and Welding Research Institute (JWRI), Osaka University,
for giving financial support under JWRI International Joining Research Collaboration(JIJReC) 2020 program, opportunity and providing all the facilities to carry out theexperiment. It is a great pleasure to have the opportunity to work with the excellent
researchers in Prof. FUJII¶s lab.
