Abstract
In this study, Ti-10Mo alloy powder and sintered bodies were successfully fabricated using a threestep process of acid/organic solvent cleaning, hydrogenation/dehydrogenation (HDH) of bulk Ti-Mo scrap, and pressureless vacuum sintering of the alloy powder. This process can be used to recycle valuable Ti alloy. And unlike remelting-based recycling processes, in..... More

Abstract
In this study, an effective method is demonstrated for fabricating titanium sputtering targets, which are used to fabricate thin films in the semiconductor industry. The method is an alternative to the existing electron beam melting (EBM) process under high vacuum. Titanium sputtering targets used in the production of semiconductors must..... More

Abstract
Ti has excellent properties but is more expensive than other materials due to its high melting point, high reactivity and difficult processability. One way to lower the production cost of Ti products is to recycle Ti scraps. Before recycling Ti scraps, pretreatment to remove contamination is essential. Ti scraps can..... More

Abstract
In this study, an eco-friendly pretreatment process was developed to recycle titanium turning scraps and ferro-titanium ingots with low gaseous impurities were prepared using recycled titanium turning scraps. The amount of gaseous impurities of titanium scraps before removing the machining oils on the surface was as high as 20000 ppm...... More
