0.19C - 1.17Cr 강의 냉간인발조직과 기계적 성질
The Microstructure and Mechanical Property of 0.19C-1.17Cr Steel with Cold Drawing
초록
The microstructure and mechanical property of 0.19C-1.17Cr steel were investigated with cold drawing. This commercial steel has the microstructure that is consist of ferrite and pearlite. The tensile and yield strength are increased as the reduction ratio of cold drawing is increased. It was clear that mechanical properties could be improved by combination of the heat treatments and reduction ratio. Yield strength. tensile strength, and impact value were formulated as a constitutive function of cold drawing ratio, respectively.
