| Abstract: | ??The isothermal strain- induced precipitation behavior of Fe- Cr- Ni heat- resistant alloy at temperature of 600, 650, 700, and 750?? and compression of 0. 4 on a Gleeble- 3500 thermal mechanical simulator was studied by stress relaxation method. The experimental results show that the PTT curve of the material is a typical C curve, and the fastest precipitation temperature is about 650??. There are three kinds of precipitates in austenite of this material, M23C6, NbC and Laves- Fe2Nb, and nanometer NbC is the main precipitation strengthening phase. |
