【摘要】 选取广泛应用的轴承材料GCr15钢进行了退火、冷轧成形、淬火实验。测试了冷轧前后环件的显微硬度变化和分布,观察了原始环件、冷轧成形环件、淬火环件和冷轧-淬火环件试样的组织状态和变化。揭示了GCr15钢在冷轧-淬火工艺中的微观组织演化规律,阐明了冷轧-淬火工艺对轴承环产品性能的影响机理,为轴承环件产品冷轧-淬火组织性能控制提供了依据。更多还原

【Abstract】 The experiments of annealing,cold ring rolling,quenching have been made with steel GCr15,which has been widely used as bearing material.The microhardness of rings before and after cold ring rolling has been tested,and the microstructure and the transformation of rings in states of original,cold rolled, quenched,cold rolled-quenched have been observed.The microstructure evolution law of steel GCr15 during cold ring rolling-quenching and the effect mechanism of cold ring rolling-quenching process on the performance of bearing ring have been revealed.The results provide a guideline to control the performance of bearing ring made from cold ring rolling and quenching.更多还原
