大型转子锻件不同半径处组织与性能的研究

Research on Microstructure and Property of Different Radii Areas on Large Rotor Forgings

对大型转子锻件28CrMoNiV59钢不同半径处的微观组织和力学性能以及其相互关系进行研究。分析该大型转子在不同半径处由于冷却速度的不同而导致的微观组织差异,对其强韧性的影响机理进行探讨。

The paper researchs the microstructure, mechanical property and their relationship of the different radii areas on large rotor forgings and the difference in the microstructure caused by different cooling speed as well as the mechanism that has effect on the strength and toughness.
