Titanium Alloys Developed by Nippon Steel & Sumitomo Metal Corporation

Titanium alloys as structural materials developed by NSSMC are introduced. Those alloys were developed for aiming at being used in the field of non-aviation industries includ ing automotive parts and utility goods, and actually applied in these fields. The alloys intro duced in this article are developed with various alloy design bases; for example, utilization of inexpensive and common alloying elements such as Fe and Cu, and the effective extraction of advantages of conventional alloying elements, such as V and Zr. As a result, all of the alloys have characteristic high-functions. Surrounding technologies needed for actual use such as forming, heat treatment, welding etc. in addition to materials properties in the actual circumstances during the use are fully prepared, and the alloys are as user-friendly as the conventional alloys.
