热处理技术是电子机械产品生产过程中不可缺少的工艺环节;是构成整机生产不可分割的组成部份。它直接关系到产品质量,同时,在工艺装备的制造中,也十分重要。实践证明,它是发挥材料潜力的重要手段。目前,全世界正面临着第四次工业革命,而这场革命的主要技术如新材料、新能源、激光、电子计算机的广泛应用等,都 Heat treatment technology is an indispensable process in the production of electronic machinery products; it is an integral part of the production of complete machine. It is directly related to product quality, at the same time, in the manufacture of process equipment, is also very important. Practice has proved that it is to play an important means of material potential. At present, the entire world is facing the fourth industrial revolution, and the major technologies of the revolution such as new materials, new energy sources, lasers, and the widespread use of electronic computers are all
