Conclusions
- 1.
Rapid quenching causes supersaturation of the matrix with alloying elements, an abrupt refinement of the second phases, and even amorphization of the matrix of alloys type Fe−Mo (Cr, V)−B(C); this increases their hardness and strength, and at the same time it also somewhat increases their ductility.
- 2.
Cyclic tempering at 550–650°C reduces the hardness of alloys of the system Fe−Mo−B, whether or not they contain carbon. Adding chromium and other high-melting metals to alloys increases the stability of the rapidly quenched state, and thereby helps retain their good mechanical properties in cyclic tempering.
