    Abstract: The present invention discloses a nanoporous copper-zinc-aluminum shape memory alloy and a preparation method and an application thereof. According to the method, firstly a pure Cu block, a pure Zn block and a pure Al block are proportioned in a certain mass ratio before being smelted to obtain a copper-zinc-aluminum alloy ingot; the obtained copper-zinc-aluminum alloy ingot is melt spun using a copper roller rapid quenching method under vacuum protection to obtain an ultrathin strip CuZnAl master alloy which is then subjected to an etching treatment with a solution containing chloride ions at a temperature of 0˜80° C. for 10˜300 minutes to obtain a nanoporous Cu/CuZnAl material; and finally the nanoporous CuZnAl material is sealed in a high vacuum quartz tube for a heat treatment to obtain a nanoporous copper-zinc-aluminum shape memory alloy having a superelastic single ? phase at room temperature.
