Background

Annealing, normalizing, quenching and tempering are four heats in the overall heat treatment, wherein quenching and tempering are closely related and are often used in a matching way, and the quenching and tempering are not indispensable. The four fires are different in heating temperature and cooling mode, and different heat treatment processes are developed. In order to obtain a certain strength and toughness, a process combining quenching and high-temperature tempering is called tempering. After some alloys are quenched to form supersaturated solid solutions, they are maintained at room temperature or at a slightly elevated temperature for an extended period of time to increase the hardness, strength, or electro-magnetic properties of the alloy. Such a heat treatment process is called aging treatment. The method of effectively and tightly combining the pressure processing deformation and the heat treatment to ensure that the workpiece obtains good strength and toughness matching is called as the thermomechanical treatment; the heat treatment in negative pressure atmosphere or vacuum is called vacuum heat treatment, which not only can make the workpiece not be oxidized and not decarburized, keep the surface of the treated workpiece smooth and improve the performance of the workpiece, but also can introduce a penetrating agent to carry out chemical heat treatment. The surface heat treatment is a metal heat treatment process for only heating the surface layer of a workpiece to change the mechanical property of the surface layer. In order to heat only the surface layer of the workpiece without introducing excessive heat into the workpiece, the heat source used must have a high energy density, i.e., a large amount of heat energy is applied to the workpiece per unit area, so that the surface layer or part of the workpiece can reach a high temperature in a short time or instantaneously. The main methods of surface heat treatment include flame quenching and induction heating heat treatment, and the commonly used heat sources include flame such as oxyacetylene or oxypropylene, induced current, laser, electron beam, and the like.
