  • The result shows that tempered martensite has apparent lath character when temper is between 740 ~ 780 , and the hardness of welded joint is 264 ~ 237hv , which can get better performance of the welded joint the lath character of martensite in welded joint disappears , and the carbide in the tempered sorbite of the base metal will aggregate when temper temperature is above 780 , and the hardness and plastic property will reduce obviously
    结果表明，在740 ~ 780之间回火，焊缝硬度为264 ~ 237hv ，回火马氏体板条特征明显，可以获得优良的焊接接头性能；回火温度超过780 ，焊缝板条马氏体特征消失，母材回火索氏体中碳化物产生偏聚，硬度、塑性明显降低。
  • 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。
  • Low - relaxation prestressed steel wire is one kind of high degree of strength steels , and it is well used in construction industry . this paper based on the product technics , analysis the electric control system in detail . this thesis focuses on the control of the temper temperature , which is the core technics parameter
    低松弛预应力钢丝是一种很有前途的高强度建筑用钢材，本文根据低松弛预应力钢丝稳定化处理生产线的工艺要求，对其电气系统进行了全面、细致的分析，对重要的工艺参数?回火温度的控制进行了详细讨论。
  • The principle of multi - method and multi - parameter is suggested , which should be followed during characterizing microstructures of alloy steels by ultrasonic not method . ultrasonic velocity ( c , ) of transformation products through different heat processes of three steels was measured by high - accuracy ultrasonic installation . the velocity of quenched microstructure of 38crmoal is the lowest , which gradually increases with increasing tempering temperature between 200 ? and 650 ? after quenching process
    利用ti - 40n高精度超声波测厚仪，研究了超声波在不同钢种、不同热处理转变产物中的超声波速度c _ 1 : 38crmoal钢淬火组织c _ 1最小，淬火后在200 650范围内进行回火处理时，随回火温度的升高， c _ 1逐渐升高， hrc与c _ 1之间具有较好的相关性；正火组织的c _ 1介于淬火后中温回火及高温回火产物组织的c _ 1之间。
