The relationship between the γ/(γ+δ) boundary temperature Tδ of austenitic steels and the equivalent weights of [Crl and [Ni] and the variation rule of the δ—phase volume with the temperature are studied With the aid of computer,the regressives expression derived from the experimental results are Tδ(℃) = T4 -21.2[Cr] +15.8[Ni]-223. Vδ(%)=0.715 exp 0.015(T-Tδ).
