【摘要】 研究了Ce对ZG75CrM0钢中非金属夹杂物的影响．结果表明，Ce可显著减少钢中夹杂物的含量、提高钢的洁净度、并使其些夹杂物性态改变；钢的室温塑韧性、抗热疲劳性、高温抗氧性均有明显提高．更多还原

【Abstract】 Study is made on the influence of Ce on the non - motallic impurities in therolled steel. The results show that,Ce can markedly decrease content of non-metallic impurities and crease cleanliness of steel,and modify characteristis of some impurities,and resultin greatly increasing plasticity,thermal fatigue resistance,high temperature oxidation resistance of the steel更多还原
