摘    要:随着工业技术的不断进步,气体保护焊接工艺越来越多地受到重视和应用。本文对CO2气体保护焊丝品种中应用最广泛的H08Mn2SiA钢不同变形量的试样进行常规力学性能检验和显微硬度检测。分别对不同变形量的试样,经过不同温度的再结晶退火后测定铁素体晶粒和显微硬度。为了表示各因素对H08Mn2SiA钢冷拔加工硬化特性及再结晶规律的影响趋势,对试验数据进行了线性回归。H08Mn2SiA钢因含有较多的Mn和Si,合金铁素体有较强的加工硬化特性。工业应用的再结晶退火工艺以640~660℃为佳。在以缩短加热周期为目的的工艺操作中采用700℃或稍高一点的再结晶温度加热,不会使铁素体晶粒长得过分粗大。

关 键 词:气体保护焊丝用钢  加工硬化  退火再结晶

Abstract:This paper introduces the characteristics Of workhardening and recrystallization of 0.08C 2Mn 1Si steel that widely used to CO2 welding. In order to impress the changes of the characteristics of workhardening and the recrystallization of H08Mn2SiA steel, a regress method was adopted in experiment. The H08Mn2SiA steel has good characteristics of workhardening.The best temperature for the industrial technology of recrystallization is from 640℃ to 660℃.In order to shorten the time, it is possible for recrystallization temperature to heat steel ill 700℃ or higher temperature.
Keywords:steel for CO 2 welding  workhardening  recrystallization
