Ti-Pt Alloys form mechanical milling. 47th Microscopy society of Southern Africa (MSSA 2009).

Durban UKZN Westville campus, 08 - 11 December 2009The high temperature ß-TiPt phase has been shown to undergo a martensitic transformation upon quenching to room temperature. The martensitic transformation results from a transformation of the parent B2 cubic structure to the martensitic B19 orthorhombic structure at a temperature of approximately 1000oC. The martensite phase results in shape memory effect being observed in this alloy at this temperature. Other alloys such as TiNi and TiPd have also been investigated for the martensitic transformation and shape memory effect. The initial alloys used in the studies were arc melted then cast for TiPd and arc melted then cast or mechanically alloyed for TiNi. The shape memory effect in these alloys has been observed to occur at temperatures of 520oC maximum in these alloys. A few researchers have studied the martensitic transformation in TiPt alloys using arc melted cast samples. In this work high temperature shape memory alloys are targeted using powder metallurgy as a processing route.enTi-Pt AlloysMechanical millingMartensiticPowder metallurgyMicroscopy societyMetal processingTiNi alloysTiPd alloysConference PresentationNxumalo, S., Chikwanda, H., & Machio, C.
