“…Again, further increase in Hf content results in little change in the value of the elastic modulus. The increase in the elastic modulus brought about by Hf can be explained by the precipitation of N-phase [14]. Although the elastic modulus is increased by introducing Hf to the Ti-40Nb alloy, the modulus value of the Ti-40Nb-xHf alloys is still substantially lower than that of other Ti alloys listed in Table 1.…”

“…The ␣ precipitation is generally recognized to increase Young's modulus in ␤ Ti alloys. For example, Bowen reported that Young's modulus of ␣ phase is two times as high as that of ␤ phase [15], and Fan showed Young's modulus of ␣ phase of 113 GPa [16]. As shown in Fig.…”

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-3.0Al alloy was developed. This alloy has good tensile properties, i.e. about 1 GPa as tensile strength, about 20% as elongation and about 50% as reduction in area, in solution treated state. It is very important that effect of cooling rate from solution treatment temperature on tensile properties is investigated, because diffusion coefficients of Fe and Cr in beta phase are higher than other beta stabilizers, e.g. V and Mo. When a stabilizer with higher diffusion coefficient is contained in phase, isothermal ! precipitation that makes the alloy brittle becomes fast. To suppress isothermal ! precipitation, it is necessary to set the cooling rate higher than an appropriate value. In this study, the effect of cooling rate from solution treatment temperature on phase constitution and tensile properties was investigated by electrical resistivity and Vickers hardness measurement and tensile test in Ti-4.3Fe-7.1Cr-3.0Al alloy. In Ti-4.3Fe-7.1Cr-3.0Al alloy cooled by a cooling rate of 0.46 Ks À1 or more, only phase was identified by X-ray diffraction, while and phases were identified in the alloy cooled by furnace cooling, i.e. 0.
