YG1500 steel is a martensite precipitation hardening stainless steel. After solution+aging treatment, the Flat noodles martensite structure with high density dislocation and the precipitation of fine precipitation phases with dispersion distribution and coherent relationship with the matrix enable the steel to obtain high strength and toughness.
Metal forgings are a special material suitable for important fields such as aviation and aerospace, so the internal structure and performance requirements are higher than other conventional products. This article focuses on the current use of two processing methods, extrusion and forging, and analyzes and studies the microstructure and properties of hot worked metal forgings using forging, extrusion, and a combination of extrusion and forging production processes for metal forging experiments.
Due to the presence of a large amount of eutectic carbides in high alloy tool steel with pearlite, sufficient fragmentation can only be achieved through significant deformation; On the other hand, due to the influence of its alloy composition, high alloy tool steel with martensite has low plasticity, high deformation resistance, poor thermal conductivity, and high tissue stress during cooling. It is prone to defects such as cracks in the forging production process. Thus creating a contradiction that complicates its forging process. Therefore, when formulating the forging process for this type of steel, corresponding technical measures should be developed from each link to address this contradiction and ensure the quality of its forgings.
