説明

In some advanced countries, especially Japan, the ratio of elder above 65 years old to total population is rapidly increasing. It is important to develop high performance welfare goods. Therefore it is also important to develop new materials for the high performance welfare goods.<br> Titanium and its alloys are one of very attractive metallic materials for health-care and welfare goods, because these alloys have high specific strength and high biocompatibility. However, high cost of Ti alloys is disadvantage in application to the health-care and welfare goods. To overcome high cost barrier of Ti alloys, Ti-4.3Fe-7.1Cr- and -3.0Al alloys were developed. These alloys have good tensile properties, i.e. about 1GPa as tensile strength, about 20% as elongation and about 50% as reduction in area, in solution treated state.
