As an important material widely used in machinery, electronics, aerospace and other fields, the strength, toughness and wear resistance of copper alloy forgings have been the focus of research. In recent years, with the continuous progress of science and technology and the continuous improvement of technology, the strength, toughness and wear resistance of copper alloy forgings have been significantly improved. In this paper, the research progress on strength, toughness and wear resistance of copper alloy forgings is reviewed, and its future development trend is analyzed.
Strength and toughness is one of the important performance indexes of copper alloy forgings, which is directly related to its service life and safety. In recent years, researchers at home and abroad have been improving the strength and toughness of copper alloy forgings by optimizing the alloy composition, improving the heat treatment process and introducing new strengthening mechanisms.
In terms of alloy composition optimization, researchers improve the microstructure and mechanical properties of copper alloys by adding trace elements and adjusting the proportion of alloying elements. For example, adding an appropriate amount of zinc, tin and other elements can effectively improve the strength and toughness of copper alloys.
In terms of heat treatment process improvement, researchers improve the microstructure and mechanical properties of copper alloy forgings by optimizing quenching and tempering process parameters. Advanced heat treatment technologies such as isothermal quenching and high pressure quenching have also been widely used, which further improves the strength and toughness of copper alloy forgings.
In addition, new strengthening mechanisms such as nano-strengthening and composite strengthening also show great potential in improving the strength and toughness of copper alloy forgings. The strength and toughness of copper alloy can be effectively improved by introducing nano-sized particles and fibers.
Wear resistance is an important performance index of copper alloy forgings under friction and wear conditions, which is of great significance to improve its service life. In recent years, researchers have continuously improved the wear resistance of copper alloy forgings by improving the surface quality, introducing wear-resistant coatings and optimizing the friction conditions.
In terms of surface quality improvement, researchers reduce the surface defects and roughness of copper alloy forgings and reduce the occurrence of friction and wear by optimizing the forging process and adopting advanced machining technology.
To sum up, the strength, toughness and wear resistance of copper alloy forgings are the hot research areas in recent years, and remarkable progress has been made. However, there are still some challenges and problems in practical applications, such as further improving strength and toughness while maintaining good wear resistance, and developing new green manufacturing technologies. In the future, with the continuous progress and innovation of science and technology, the research on the strength, toughness and wear resistance of copper alloy forgings will continue to be in-depth. By further exploring the alloy design, optimizing the manufacturing process, and exploring new strengthening mechanisms, it is expected to achieve an overall improvement in the strength, toughness and wear resistance of copper alloy forgings, and promote technological progress and industrial development in related fields.
