Fracture precipitation hardening

The ability of steel to withstand moderate stress without plastic deformation and fracture at high temperature is its high-temperature strength. In steam turbines, hardened chromium steels with 9-12% Cr are used. If they are alloyed with some tenths of a percent of boron, small boride precipitations are formed in the iron matrix. These act as obstacles to dislocation movements (slips in the crystal grains) and by that means improve the high-temperature strength. [Pg.817]
