| 摘 要： | 试验研究了成分(%)为0.49C-0.29Si-1.65Mn、n53C-0.78Si-1.56Mn和0.54C-1.74Si-0.71Mn(60Si2MnA)3种中碳弹簧钢850℃5～120 min水冷和780～1000℃60 min水冷热处理后的脱碳敏感性和氧化失重行为。结果表明,随钢中硅含量增加,钢的脱碳层深度增加,氧化失重量减少,说明Si能增加钢中碳的扩散系数,促进钢的脱碳。

| Abstract: | The behavior of decarburization sensitivity and oxidation weight loss of three medium carbon spring steels; 0.49C-0.29Si- 1.65Mn,0.53C-0.78Si- 1.56Mn and 0.54C- 1.74Si-0.71Mn(6Si2MnA)heat-treated at 850 ℃ for 5～120 min,water cooling,and at 780～1000℃ for 60 min water cooling has been tested and studied. Results showed that with increasing silicon content in steel,the decarburization depth increased and the weight loss of oxidation decreased. It indi- cates that Si can increase coefficient of diffusion of carbon in steel to improve decarburization of steel. |
