Abstract

Ultrafine grained NiTi shape memory alloy was consolidated from Ni/Ti laminates via accumulative roll bonding (ARB) followed by hot isostatic pressing (HIP). Due to the extensive plastic deformation arising from ARB and the attainment of ultra-thin layers of both Ti and Ni laminates, the subsequent HIP processing time was significantly reduced. Differential scanning calorimetry (DSC) analysis confirms that the shape memory effect was obtained in the consolidated NiTi alloy.

Ni / Ti纳米层合纳米结构NiTi形状记忆合金

摘要

通过累积辊压结合（ARB）和热等静压（HIP），从Ni / Ti层压板固结了超细晶粒的NiTi形状记忆合金。由于ARB引起的广泛塑性变形以及Ti和Ni层压板均获得超薄层，因此可以大大减少后续的HIP处理时间。差示扫描量热法（DSC）分析证实在固结的NiTi合金中获得了形状记忆效果。
