球状渗碳体
双语例句
- Medium carbon steel ( 0. 36% C) was thermo-mechanically deformed and subsequent controlled cooled ( TMCP) to obtain refined microstructure with spheroidized cementite. It was found that ferrite grain size reduced with decreasing deformation temperature or increasing deformation strain.
采用热机械轧制工艺可使中碳钢（0.36%C左右）具有球化渗碳体的细晶显微组织，研究发现随变形温度的降低及变形量的增加其铁素体晶粒尺寸变小。
