马氏体的 meaning in Chinese
martensitic
Examples
- Martensite formation during mechanical alloying of fe - ni and martensitic transformation
机械合金化过程中马氏体的形成及相变 - The lath width of martensite can be fined noticeably by pre - strained quenching at non - dynamic recrystallization to approach nanometer magnitude ( the average width is 120nm )
采用非动态再结晶温度下的预应变-淬火，提高马氏体相变形核率，可以超细化马氏体的板条晶片宽度，使之接近纳米量级水平(平均宽度达到120nm ) 。 - Abstract : recent experimental investigations have demonstrated that the pre - deformation of shape memory alloys results in martensite stabilization opposing reverse transformation , hence leading to the expansion of transformation hysteresis
文摘:形状记忆合金经适当温度下的塑性变形可以有效地提高马氏体的稳定性，从而使相变滞后得以大幅度提高。 - The reason is that the elastic energy increases the nucleation work while the formation of primary martensite can excite the release of elastic energy in austenite to promote the formation of after martensite and intensify the tendency towards homogeneous nucleation
其原因是弹性能的存在增大了初生马氏体的形成功，而初生马氏体的形成则会激发奥氏体内弹性能的释放，弹性能的释放可促进继生马氏体形成，并增大其均匀形核倾向。 - Based on the analyses on mechanical properties , microstructure and fracture of - the microalloyed steels socrv with various heat treatment technique , it can be affirmed that various fractures arttribute to various mechanism , we can draw conclusion that the strength and toughness of microalloyed steels 50crv will be increase simultaneously by optimal heat treatment technique . to illustrate the mechanism of the strength and toughness of microalloyed steels socrv , we designed the comparative experiment and observed the microstructure of the sample which occurred at different quench and tempering temperature and different tempering time . the last experiment results were determined by the four factors : fined microalloyed elements grains , the decompound of martensite , martensite transformation of remnant austenite and the second phase precipitation
为解释微合金化50crv钢强韧化机理，本文通过对不同淬火温度，回火温度，回火时间下的力学性能指标的对比及显微分析，认为微合金元素的细化晶粒，马氏体的回火分解，残余奥氏体的转变，第二相的沉淀析出共同决定了微合金钢的强韧化情况，特别是由于微合金元素的存在，其细化晶粒及其碳氮化物的沉淀析出，导致钢的良好的强韧性，并且如果工艺满足第二相的沉淀析出强化大于回火马氏体分解引起的软化效应，会在硬度曲线中产生明显的二次硬化现象。
