14CrODS铁素体钢的制备及其拉伸性能
Preparation and Tensile Properties of 14CrODS Ferritic Steel
摘要
Abstract
A ODS ferritic steel powder with the chemical composition (mass fraction/%)of Fe-14Cr-0. 5Ti-0. 35Y2O3 was prepared by mechanically alloying (MA), and the element distribution was ho-mogenous. The MA powder was consolidated by hot isostatic pressing (HIP), followed by forging and annealing. Compared to 14CrNA steel without ODS particles, the tensile strength of 14CrODS steel was excellent,but not so good compared with MA957, thus need improvement. The ductility of 14CrODS was much better than MA957, and could be enhanced further by forging. However, residu-al stress existed during forging, making the 14CrODS steel brittle in room temperature tensile tests. Annealing could remove the residual stress and significantly improve the ductility of 14CrODS, which was more excellent than MA957.关键词
