Abstract : The effects of hardening of steel under the action of a focused Q-switched laser pulse with intensity > 10 to the 11th power W/squared cm. are examined. The effect of hardening at a depth of approximately 10 micrometers (observed in application of the laser pulse to KhVG (chrome-tungsten-manganese) steel) is explained by displacement of the zone of thermal saturation from the surface after termination of a pulse with duration of approximately 10 ns. The possible increase in the zone of thermal hardening with a further increase in radiation intensity is discussed. (Modified author abstract)
