| 摘 要： | 对低层措能Fe—26Mn—6Si—7Cr—lCu形状记忆合金和0Crl3Ni5Mo不锈钢进行了空蚀试验。结果表明，Fe—26Mn—6Si—7Cr—lCu形状记忆合金杭空蚀性能优于0Crl3Ni5Mo不锈钢。空蚀过程中应变诱发马氏体转变是该形状记忆合金具有良好杭空蚀性能的主要原因。

| Abstract: | Cavitation erosion of Fe 26Mn 6Si 7Cr 1Cu shape memory alloy with low stacking fault energy and 0Cr13Ni5Mo stainless steel has been investigated. It is showed that Fe 26Mn 6Si 7Cr 1Cu is more resistant to cavitation erosion than 0Cr13Ni5Mo stainless steel which is commonly used as erosion resistant material in hydraulic machinery. The high cavitation erosion of Fe 26Mn 6Si 7Cr 1Cu alloy is mainly atributable to its strain induced martensitic transformation which can absorb more impact energy and reduce the material loss. |
