Ductile fracture of metals generally refers to the internal microdefects of metal materials, such as microcracks and microvoids, which will nucleate, grow, converge and lead to the gradual deterioration of materials after severe plastic deformation under the action of external loads. When a certain degree of strain is reached, macroscopic fracture of materials will occur. The main characteristics are obvious macroscopic plastic deformation, such as excessive bulging of the container, excessive elongation or bending of the forgings, etc., and the fracture size has a great change compared with the original size.
Forging production is one of the main processing methods to provide machine parts blank in machinery manufacturing industry. Through THE FORGING OF HANGSHENG FORGING COMPANY, not only the shape of the mechanical parts can be obtained, but also the internal organization of the metal can be improved, and the mechanical and physical properties of the metal can be improved. In general, the important mechanical parts with high force and high requirements are mostly manufactured by forging production method. Such as turbine generator shaft, rotor, impeller, blade, guard ring, large hydraulic press column, high pressure cylinder, rolling mill roll, internal combustion engine crankshaft, connecting rod, gear, bearing, and defense industry aspects of the gun and other important parts, are produced by forging.
Therefore, forging production is widely used in metallurgy, mining, automobiles, tractors, harvesting machinery, petroleum, chemical industry, aviation, aerospace, weapons and other industrial sectors, is in daily life, forging production also has an important position.
