顾名思义,形状记忆合金是一种对形状具有记忆功能的合金。这种合金在某温度(Ms点)以下改变其形状后,当温度升高到某温度(As点)以上,便能逐渐恢复到形变前的形状,在恢复原先形状过程中外形的变化将产生驱动作用。由于形状记忆合金具有感温和驱动的双重作用,所以受到人们普遍的重视,并得到了广泛的应用。 As the name implies, a shape memory alloy is an alloy that has a memory function on the shape. This alloy changes its shape below a certain temperature (Ms point). When the temperature rises above a certain point (As point), it gradually returns to the shape before the deformation, and the change of the appearance during the restoration of the original shape will occur Drive effect. As shape memory alloy has the dual role of temperature sensing and driving, it has received widespread attention and has been widely used.
