报告题目(英文)：Heat treatment effects in metamagnetic Ni-Mn based shape memory alloys

报告内容简介：Metamagnetic shape memory alloys are an interesting class of materials capable of undergoing a reverse martensitic transformation imposed by a magnetic field. As such they may be intersting as a new class of shape memory alloys for actuation application as well as for new generation magnetic cooling, since upon the transformation they simultanously show a considerable adiabatic temperature change. The transformation may take place between the ferromagnetic/magnetic austenite and weak magnetic martensite. The magnetic ordering can be well controlled either by composition or thermal treatments, which modify the magnetic exchange inteaction and may thus effectively alter the magnetic contribution to the transformation entropy change with consequences for the functional performance. In this talk a basic properties of metamagnetic shape memory alloys based on Ni-Mn-Sn are briefly reviewd with focus on thermal treatment effects for optimising their performance.
