纳米片层相增强TiNi基合金复合板材的制备方法
摘要：
本发明提供的是一种纳米片层相增强TiNi基合金复合板材的制备方法。(1)对TiNi基形状记忆合金箔与增强金属箔进行表面酸洗；(2)将酸洗后的TiNi基形状记忆合金和增强金属箔交替叠放并保证最外层为TiNi基合金箔，利用烧结工艺烧结成型；(3)将烧结成型的TiNi基合金复合材料真空密封在不锈钢或纯Ti包套内，在室温～500℃温度下反复轧制；(4)在200℃～600℃范围内进行退火处理，得到纳米片层相增强TiNi基复合材料板材。本发明具有工艺简单、易于调控、对设备要求低等优点。利用本发明制备的纳米片层相增强TiNi基复合板材可适用于阻尼构件、驱动器与医疗器械等。
摘要（英）：

The invention provides a preparation method of a nanosheet layer phase reinforced TiNi-based alloy composite plate. The preparation method comprises the following steps: (1) performing surface acid cleaning of TiNi-based shape memory alloy foil and reinforcing metal foil; (2) alternately stacking the TiNi-based shape memory alloy foil and the reinforcing metal foil that are subjected to acid cleaning while ensuring that the outermost layer is the TiNi-based alloy foil, and performing sintering formation by a sintering process; (3) sealing a TiNi-based alloy composite material formed by sintering into a stainless-steel or pure Ti sheath in a vacuum way, and performing rolling repeatedly within a temperature range from the room temperature to 500 DEG C; and (4) performing annealing treatment at 200-600 DEG C to obtain the nanosheet layer phase reinforced TiNi-based alloy composite plate. The preparation method has the advantages of simple process, easiness in regulation and control, low equipment requirement and the like. The nanosheet layer phase reinforced TiNi-based alloy composite plate prepared according to the preparation method is applicable to damping elements, drivers, medical instruments and the like.
