| Abstract: | Effect of aging time at 760℃ on microstructure and mechanical properties of 0Crl6Nil6 austenitic heat- resistant steel was investigated. The results show that with the prolongation of aging time, the amount of intragranular precipitates increases, and both tensile strength and yield strength firstly increase and then decrease. The tensile strength of the steel reached a maximum of 730.9 MPa after solution treating at 1050 ℃ for 4 h and aging at 760 ℃ for 5 h. |
