Experimental Research on High-temperature Diffusion Annealing Process of Steam Turbine Rotor Forgings
摘要
Abstract
Based on experiments,combined with the practical production of high pressure steam turbine rotor forgings,the variation of grain size,microstructure and mechanical properties in differ-ent holding times and forging fire times were studied,the influences of high-temperature diffusion an-nealing on 30Cr1Mo1V steel were revealed as well.The results show that the banded structure pro-duced by dendritic segregation and forging deformation can be eliminated by high-temperature diffu-sion annealing.The grain size is smaller only before forging high-temperature diffusion annealing. The transverse toughness of the 30Cr1Mo1V steel can also be improved by homogenization.The grain and the structure are coarsened because of long time high temperature heating after forging,which leads to the worse toughness of the steel.Meanwhile,the plasticity of 30Cr1Mo1V steel is not influ-enced by the high-temperature diffusion annealing obviously.关键词
