<Original Papers>Mechanical Working of a TiNi Shape Memory Alloy and it\u27s Application

Mechanical working of a TiNi shape memory alloy by machining was discussed as well as attempts to fabricate pipe connectors. The results obtained so far are satisfactory. Although the process of machinability is difficult and complex, the working method presented in this paper offers a new possibility

Study on the Boron-Nonstoichiometry and Properties of Perovskite-Type YRh3B

Polycrystalline samples ofYRh3Bx are prepared by the arc melting synthetic method. Perovskite-type cubic phase (space group : Pm3m) of YRh3 Bx exists in the range of 0.50 ≤x≤1. Lattice parameterαof YRh3Bx depends on x, and varies linearly from a = 0.416347(4) nm (x = 1.000) to 0.408776(7) nm (x = 0.500). The value of Vickers microhardness ofYRh3Bx ranges from 7.7 to 2.7 GPa. Hardness decreases with decreasing of boron content x. The TEM observation reveals that the anomalous softening of hardness in the vicinity of x = 0.5 for YRh3 Bx is caused by the appearance of the modulated structure. By the TG-DTA, oxidation of YRh3B1.ooo starts at 541 K. The weight gain by oxidation is 11.4 %. The oxidized product is mixed phase of YB03 and Rh. The densi!Y of states at the Fermi level, D (EF), of YRh3 B1 .ooo (20 at.%B) is indicated to be slightly larger than that of YRh3B0.706(15 at.%B)
