摘要： An alloy, a raw workpiece, a component and a method contain or create austenites. The new alloy allows austenites to be formed or treated at higher temperatures, with new heat treatments also being used. Various heat treatments may be carried out with reference to the strength/toughness balance and notch sensitivity.
