phase precipitation meaning in Chinese
相析出
Examples
- Kinetics of 8 " phase precipitation and influence of electric field applying during solution process are studied by differential scanning calorimetry ( dsc ) technique
以示差量热分析技术( dsc )研究相析出的动力学及固溶电场的影响。 - 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。 - Caculation is carried through adopting mechanism function of the first order reaction , f1 : f ( ) = l - . the results have good linear relativities , a , the precipitated fractions are excellently representative , and f1 is ascertained the most probably mechanism function of " phase precipitation . the electric field reduces activation energies of " phase precipitation and average sizes of " particles both in 2090 and 1420 alloys
采用一级反应的模型函数f1 ： f ( ) = 1 - ，计算了相析出的动力学，计算结果具有良好的线性相关性，并且具有很好的代表性，确定f1为相析出的最概然机理函数；电场固溶使2090合金和1420合金升温时效过程的相析出激活能有一定程度的减小，并减小了相颗粒的平均尺寸。
