Description

[0001] technical field [0002] The invention relates to a method for forging a gasoline engine connecting rod blank by using modified metal powder, and belongs to the technical field of new material processing. [0003] Background technique [0004] Powder metallurgy is a process technology for producing metal or using metal powder (or a mixture of metal powder and non-metal powder) as raw material, forming and sintering to manufacture metal materials, composite materials and various types of products. Powder metallurgy has similarities with the production of ceramics. Therefore, a series of new powder metallurgy technologies can also be used for the preparation of ceramic materials. Due to the advantages of powder metallurgy technology, it has become the key to solve the problems of new materials and plays a pivotal role in the development of new materials. [0005] Powder metallurgy has unique chemical composition and mechanical and physical properties, which cannot be...
