| Abstract: | Chemical compositions and mechanical properties of typical 18%Ni maraging steel and cobalt-free maraging steel are introduced. The current three technologies of grain refinement are reviewed,including cyclic phase transformation treatment, thermomechanical treatment and equal channel angular pressing. At last,the development tendency of maraging steels is forecast and the ways for further study of strengthing-toughening and fine grain strengthening are proposed. |
