摘要
试验研究了含Nb0.037%微合金钢形变奥氏体→先共析铁素体等温转变分数f_v随等温时间t的变化规律。结果表明1n1n(1-f_v)^(-1)-Int关系并不严格遵循Avrami方程,而是呈两段直线状。对此给出了与Cahn不同的理论解释。
The volume fraction variation of proeutectoid ferrite formed isother-mally from deformed austenite with isothermal time has been examined experimen-tally. The results show that ln ln (1--f_v)^(-1) vs ln t relation does not follow the Avr-ami equation strictly and consists of two straight lines. By comparing the differen-ces between the results and Cahn's theory, the authors' idea has been expounded.
