Abstract (en)
A method of processing a workpiece of maraging steel includes receiving a workpiece (22) of maraging steel that has been subjected to thermomechanical processing (38, 36) at an austenite solutionizing temperature and then directly aging (26) the workpiece of maraging steel at an aging temperature to form precipitates within a microstructure of the workpiece (42) of maraging steel, without any intervening heat treatments between the thermomechanical processing and the direct aging.
