With increasing energy input the necessary preheating temperature decreases : if 100 ° C was necessary at 12 kJ / cm , only 75 ° C was required at 20 kJ / cm . This is valid for an tvalue of 4.3 ml / 100 g Fe .

The toughness was evaluated by the value of absorbed energy using an instrumented Charpy impact test machine which could divide the absorbed energy into crack - initiation energy ( Ei ) and crack - propagation energy ( Ep ) .
