Preparation of Low Oxygen Content Powder from Ti-6Al-4V and Ti-8Al-1Mo-1V Alloy Scraps with Deoxidation in Solid State Process

Autor: Hanjung Kwon, Ki-Min Roh, Jae-Won Lim, Jung-Min Oh, Chang-Youl Suh

Publikováno v: Journal of the Korean Institute of Resources Recycling. 24:21-27

The present study describes the process of producing low oxygen content alloy powder from Ti-6Al-4V and Ti-8Al-1Mo-1V (AMS 4972) alloy scraps using hydrogenation-dehydrogenation (HDH) and deoxidation in solid state (DOSS) processes. Each prepared pow

Preparation of Ti Ternary Alloys by Addition of Si to Ti-Mo Alloy Scraps for Carbonitride Application

Autor: Hanjung Kwon, Chang-Youl Suh, Back-Kyu Lee, Jung-Min Oh, Jae-Won Lim, Ki-Min Roh

Publikováno v: MATERIALS TRANSACTIONS. 56:167-170

In this study, Ti-Mo-Si ternary alloy ingots were prepared by the addition of Si (0.252.0mass%) to Ti-10Mo alloy scraps in order to produce the raw materials for titanium carbonitride composites. To investigate the effects of Si addition, the prepa

Comparison of deoxidation capability for preparation of low oxygen content powder from TiNi alloy scraps

Autor: Jung-Min Oh, Hanjung Kwon, Chang-Youl Suh, Wonbaek Kim, Ki-Min Roh, Jae-Won Lim

Publikováno v: Powder Technology. 253:266-269

Low oxygen content TiNi alloy powder was produced from TiNi alloy scraps by three types of deoxidation after the hydrogenation–dehydrogenation (HDH) process. The TiNi alloy scrap had a Ti:Ni weight ratio of 7:3. After the HDH process, the TiNi allo
