More specifically, these alloys undergo a transformation from a low-temperature, less ordered phase (martensite) to a high-temperature, more ordered phase (austenite), enabled by the unique alloy compositions typically involving metals such as nickel, titanium, copper, and zinc.

更具体地说，这些合金经历了从低温、有序相（马氏体）到高温、有序相（奥氏体）的转变，这得益于独特的合金成分，通常涉及金属，如镍、钛、铜、和锌。
