摘要/Abstract

摘要： 通过光学和扫描电子显微镜,运用定量金相技术,分析计算高碳钢(%:0.56～0.63C、0.60～0.71Mn、0.23～0.28Si)铁索体含量和珠光体片间距,建立高碳钢线材的组织和屈服强度(σ_s)之间关系的数学模型:σ_a(Pa)=104.52×10^-6+161.70(1-f_a^1/3)S^-1(m),其中fa~-铁素体的体积百分数,S-珠光体的片层间距。模型的计算值与实验值的相对误差为2.9%。

Abstract: Based on analyzed and calculated finite content and pearlite lamellar spacing in (0. 56 *0. 63C, 0. 60 ~ 0. 71Mn, 0. 23 〜0. 28Si) high carbon steel by optical and scanning electron microscope using quantimet technique, the mathematical model for relationship between structure and yield strength of high carbon steel wire has been established that is yield strength σ_a.( Pa) = 104. 52 x 10^-6 + 161. 70 (1 - f_a^1/3 )S^-1(m), where/,- volume fraction of ferrite, S・ pearlite lamellar spacing. The relative error of the calculated value by model with examined value is 2. 9%.
