Martensitic transformations in gold-titanium, palladium-titanium and platinum-titanium alloys near the equiatomic composition
TLDR
In this article, the martensitic transformations involved were studied by X-ray diffraction and the composition dependence of the Martensitic-transformation characteristics, such as Ms, Mf, As and Af-temperatures, were determined.Abstract:
Alloys of compositions near AuTi, PdTi, and PtTi are B19-type orthorhombic at room temperature and, at higher temperatures, have an ordered CsCl-type structure (B2-type). The martensitic transformations involved were studied by X-ray diffraction. The composition dependence of the martensitic-transformation characteristics, such as Ms, Mf, As and Af-temperatures, were determined. Lattice constants of the high-temperature phases are given.read more
