The integrally formed multimaterial forging die has good toughness gradient and excellent combination between base and work layer. The hard surface layer is made of MDY501 microslag high performance powder core wire, with a hardness of 54HRC, high hardness, strength, good thermal stability, fatigue resistance, wear resistance and good combination with the transition layer. Meanwhile, it has a good combination with the substrate and matrix, and has a good transition effect in hardness and strength.

The transition layer is made of MGY381 microslag powder core wire with high performance, and its hardness is 38HRC, which has high strength, hardness and good toughness. It has good yielding property under high pressure, which can effectively prevent the fracture failure of 5CrNiMo matrix under high pressure. Among them, the base layer adopts MGY281 microslag powder core wire with high performance, and its hardness is 28HRC, which is a kind of crack resistant material with good plasticity. The arc additive developed is used to manufacture specialty metal powder core wire and its forming equipment to realize the overall forming of multimaterial forging die (see Fig. Therefore, the idea of multimaterial forging die manufacturing/reengineering of “base layer+transition layer+hard surface layer” is put forward here. It is difficult for a single material forging die to fully meet the above requirements, which greatly affects the service life of the die. In addition, the contact surface should also have good thermal wear and thermal melt loss.

The forging die itself not only needs to have good mechanical properties, such as high temperature strength and hardness, good toughness, and wear resistance, in the process of work also needs to have good thermal conductivity, heat resistance fatigue, thermal stability and oxidation resistance. The service environment is complex and changeable, which requires high performance of the mold. Contact FIA for bulk order prices.Forging die in the process of service not only the effect of force, but also by the influence of temperature. Principal uses: training, education, and information for producers and their employees, customers, students and others interested in the open die industry. Includes overview on the manufacture of seamless rolled rings. Handbook compiles information on manufacturing equipment methods and design considerations of open die forgings. Significant changes, technical developments and specialization in the production of open die forgings are chronicled.
