补充资料:形状记忆合金
形状记忆合金 shape memory alloy 具有形状记忆效应的金属材料。形状记忆效应是指合金经变形后,在一定条件下仍能恢复到变形前形状的能力。形状记忆效应是利用合金的马氏体相变与其逆转变的特性,即在高温下将处理成一定形状的合金急冷下来,再在低温下经塑性变形成另一种形状,然后加热到一定温度,此时合金产生马氏体相变,并逐渐恢复到低温变形前的原始状态。通常形状记忆合金的这种马氏体相变为可逆的热弹性马氏体相变,在相变过程中,马氏体的增加不是依靠新生的马氏体相,而是依靠旧马氏体相的长大,即随温度下降马氏体长大,温度升高马氏体缩小,马氏体的长大和缩小随温度改变而弹性地发生变化。 已实用的形状记忆合金主要有镍钛系、铜系和铁系合金。形状记忆合金最早用于制作管接头和紧固件。镍钛系合金现已用于制造人造卫星天线,这种天线可卷入卫星体内,当卫星进入轨道后,借助于太阳热能或其他热源能在太空展开。在医学领域,形状记忆合金也获得广泛应用,如制成血栓过滤器,脊柱矫形棒、牙齿矫形唇弓丝、人工关节、人造心脏等。此外,形状记忆合金还用于制造安全报警装置,制成小型固体热机用于能源开发等。 |
