【正文】 。%~%時對材料的峰值應(yīng)力和斷面收縮率同時有大幅度提高,%~%時峰值應(yīng)力和斷面收縮率沒有顯著的變化,在1200℃時略有下降。氮的加入對動態(tài)再...【英文摘要】20MnSi steel rebar can be made available to steel structure, construction and machine parts. The main drawback of 20MnSiⅡgrade rebar which is used widely is the low intensity, only ,steel consumption is greatly in the building engineering. Nitrogen alloying can make the adhesion of segregation of metal atoms and grain boundaries strengthened, nitrogen still play important role in obstructing grain growth
