- The influences of isothermal quenching temperature on the retained austenite and mechanical properties of adi were studied
摘要研究了等温淬火温度对adi中残余奥氏体及其力学性能的影响。 - Quenching and tempering were chosen to strengthen the material . the quenching temperature and time were adjusted based on the hardness measurement
选择淬火和回火作为本课题的热处理工艺，并用硬度法确定可行的淬火温度和保温时间。 - 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。 - The results show that , with the quenching temperature ( 270 ~ 380 ) increasing , the carbon content and percentage content of retained austenite increase first and then decrease , which are up to a maximum value at 360 ; the tensile strength of adi decreases ; the elongation and impact ductility of adi increase first and then decrease , which are up to a maximum value at 360 ; but the hardness of adi decreases first and then increases , which is up to a minimum value at 360
结果表明，在试验温度范围内( 270 ~ 380 ) ，试样中残余奥氏体的含碳量及其含量随着等温淬火温度的升高先增大后减小，均在360等温淬火时出现最大值；抗拉强度随着等温淬火温度的升高而逐渐降低；伸长率和冲击韧度随着等温淬火温度的升高先增大后减小，在360等温淬火时出现最大值；硬度则随着等温淬火温度的升高先减小后增大，当360温淬火时硬度最低。
