title: Microstructural evolution during mechanical milling of Ti/Al powder mixture and production of intermetallic TiAl cathode target

authors: Gabbitas, Brian

subjects: titanium aluminides

abstract: Titanium aluminides are of great technological interest because of their attractive mechanical properties. Mechanical milling/alloying is a promising powder metallurgical technique, which can achieve ultrafine, uniform and manipulable microstructures. In this study, we employed a recently revisited discus mill to produce a composite Ti– (50–57) at.%Al powder feedstock, which is suitable for hot consolidation to produce bulk cathode targets for physical vapour deposition (PVD) coatings. The effects of milling time, quantity of process control agent (PCA) and discus-topowder weight ratio (DPR) on the microstructure evolution of the attendant Ti/Al composite powder were investigated in detail. It was found that to produce Ti/Al composite powders with a fine particle size and a uniform microstructure, the practicable processing parameters should be 2 or 3% isopropanol addition as PCA, 12 h of milling time and at least 13:1 DPR weight ratio. Cathode targets were produced by hot isostatic pressing (HIPing) the as-milled powders. The targets were then used to produce a PVD TiAlN coating which had an average microhardness of 2400 HV.

title: Indigidata Aotearoa post-event summary report 2023

authors: Te Kotahi Research Institute

subjects: Indigenous Data Sovereignty

abstract: From the 21st to the 24th of August, the inaugural Indigidata Aotearoa 2023 was held at Te Whare Wānanga o Waikato. In recent years there has been significant advances in the fields of Indigenous data science and sovereignty. The Indigidata Aotearoa programme was designed to develop an understanding of Indigenous data science and sovereignty alongside some of the best researchers in Aotearoa New Zealand. The fully funded wānanga was open to Māori (tauira, kaitiaki, kaipakihi) participants from across Aotearoa. Applications were received from more than 35 respondents, and 23 tauira Māori attended the inaugural event.
