Effect of thermomechanical treatments on hardness and coercive force of aged austenitic alloy of invar composition

Effect of thermomechanical treatments on hardness and coercive force of aged austenitic alloy of invar composition

The effect of thermal (aging at temperatures of 500–800°C) and thermomechanical (30% deformation at 20°C and subsequent aging) treatments on the hardness and coercive force of the quenched 60N30K10F alloy has been studied. The alloy subjected to water quenching from 1150°C is shown to be a supersatu...

Zusammenfassung:The effect of thermal (aging at temperatures of 500–800°C) and thermomechanical (30% deformation at 20°C and subsequent aging) treatments on the hardness and coercive force of the quenched 60N30K10F alloy has been studied. The alloy subjected to water quenching from 1150°C is shown to be a supersaturated solid solution that can decompose upon subsequent heating. The dependences of the hardness and coercive force on the time and temperature of aging have been obtained, discussed and explained.
