Abstract


During the production of shape memory alloys, a very fine grain size should be obtained in order to obtain better mechanical properties and a good thermomechanical behaviour during cycling. The classically used grain refiners show some secondary effects on the martensitic transformations that could be at the origin of some technological problems. For this reason, a new processing method by powder metallurgy has been developed for this kind of alloys. The three proceeding stages are described: Atomization, hot isostatic pressing and hot rolling. The microstructure of the materials is characterized. The martensitic transformation and the thermomechanical properties are also studied.
