摘要:

通过物理化学相分析研究了3种不同氮含量镀锡板中固溶氮、化合氮的含量,结合相关理论计算了镀锡板中氮的固溶强化和析出强化对强度的贡献。结果表明:随着总氮含量从0.0021%提高到0.0103%,钢中化合氮含量下降10.1%,但是AlN析出相中的氮的含量上升10.7%。氮在提高镀锡板强度方面发挥重要作用,钢中总氮含量提高0.0082%,其对屈服强度的贡献值提升约30 MPa。

Abstract:

Content of nitrogen in solid solution and combined nitrogen in three different kinds of tin-plated sheet were studied by physiochemical phase analysis, the contribution of solution strengthening and precipitation strengthening played by nitrogen in the tin-plated sheet were also calculated according to related theory. The results show that with the total nitrogen content increasing from 0.0021% to 0.0103%, the proportion of combined nitrogen in the steel is decreased by 10.1%, but the proportion of the nitrogen in the AlN precipitation is increased by 10.7%. Nitrogen can play an important role in improving the strength of the tin-plated sheet, the yield strength of the steel can be promoted by 30 MPa with the total nitrogen content increased by 0.0082%.

Key words: tin-plated sheet, nitrogen, strengthening, solid solution, precipitation
