What are the application areas of powder metallurgy materials?

Powder metallurgy materials are more and more widely used in modern industry, especially in the automobile industry, household goods, mechanical equipment and other applications, powder metallurgy materials have occupied a large proportion. They already have obvious advantages in replacing low-density, low-hardness and low-strength cast iron materials, and are gradually being promoted in the application of high-hardness, high-precision and high-strength precision and complex parts, thanks to the rapid development of powder metallurgy technology. The heat treatment process of fully dense steel has been successful, but the heat treatment of powder metallurgy materials, due to the differences in the physical properties of powder metallurgy materials and the differences in the heat treatment process, there are still some defects. Each casting and smelting enterprise in the technical research of powder metallurgy materials, hot forging, powder injection molding, hot isostatic pressing, liquid phase sintering, combined sintering and other heat treatment and subsequent treatment processes in ? Powder metallurgy materials, physical properties and mechanical properties of defects in the improvement, achieved certain results, improve the strength and wear resistance of powder metallurgy materials, will greatly expand the scope of application of powder metallurgy.
