| Abstract: | It is known that some of platinum group metals base intermetallics have shape memory effect. We note PtTi because its phase transformation temperatures is at around 1273 K. The phase transformation of PtTi and the effect of Ir on the phase transformation were investigated by X-ray diffractometry (XRD), differential thermal analysis (DTA), in-situ surface observation in laser microscope, and microstructure observation in transmission electron microscopy (TEM). The shape recovery was investigated by dilatometry. Microstructure suggests martensitic phase transformation occurs in PtTi and (Pt, Ir)Ti. The shape recovery was found in some of the tested alloys. Potential of platinum group metals base intermetallics as high temperature shape memory alloys is discussed in this paper. |
