Temperature heat treatment, seemingly a rough process filled with fire and ice, is in fact an extremely precise science of materials. Through precise control of temperature and time parameters, it orchestrates a spectacular phase transition drama in the microscopic atomic world, ultimately endowing macroscopic forgings with exceptional vitality. The next time you witness those colossal machines operating steadily under immense pressure, you might recall that it is this balance between “quenching” and “tempering” that silently safeguards the backbone of modern industry
