Adverse effect of niobium and boron on hot deformation behavior of sulfur-containing steel
《Journal of Iron and Steel Research International》2024年第1期252-263,共12页Guo-ning He Shi-qi Wan Bo Jiang Chao-lei Zhang Ya-zheng Liu Chun-jing Wu 
The authors appreciate the financial support from Xining Special Steel Co.,Ltd.and student research training project of University of Science and Technology Beijing.
The hot deformation behaviors of sulfur-containing gear steel 20MnCr5 containing three different contents of Nb and B(0,0.021%Nb,and 0.024%Nb-0.0022%B)were investigated.Hot compression and tenssion tests were carried ...
