Forging is an important metal product, which is formed by processing metal at high temperature. Forgings have the advantages of high strength, high hardness and good plasticity, and are widely used in machinery and equipment, automobile industry, aerospace and other fields. In the forging process, the yield strength of forgings is an important indicator, which is the ability of forgings to undergo plastic deformation under load.

The yield strength of forgings is affected by many factors, such as forging temperature, forging speed, forging ratio, etc. Among them, the forging temperature is one of the most important factors affecting the yield strength of forgings. In general, forgings can be forged at high temperatures to obtain a higher yield strength. This is because the yield point of the metal decreases at high temperatures, making the metal material more susceptible to plastic deformation. In addition, the high temperature can also reduce the deformation resistance of the metal material, making the forging process easier.

In addition to the forging temperature, other factors in the forging process can also affect the yield strength of the forging. For example, there is a positive correlation between forging speed and yield strength, that is, the faster the forging speed, the higher the yield strength of the forging. This is because rapid forging can make the metal material in a short period of time to be subjected to greater pressure and strain, thereby increasing its plastic deformation capacity. The forging ratio is a relatively complex factor, which is related to the degree of deformation in the forging process, forging stroke and other factors, so it needs to be studied according to the specific forging situation.
