试验表明，贝氏作组织的冲击韧性和断裂韧性分别比常规淬、回火的马氏体组织提高约2倍和65％，比相同温度回火的马氏体组织提高32．9％和19．64％。GCr15钢贝氏体等温淬火的轧机轴承，解决了原马氏体淬、回火工艺而造成的套圈开裂和挡边断裂问题。经使用考核，寿命可提高66．7％～79．6％。附图3幅，表3个，参考文献5篇。
The results show that the impact toughness and fracture toughness of Bainite are about 2 times and 65% higher than that of conventional quenched and tempered martensite, 32.9% and 19.9% higher than that of martensite tempered at the same temperature .64%. GCr15 steel bainite isothermal quenching mill bearings to solve the original martensite quenching and tempering process caused by ring cracking and rib cracking problems. The use of assessment, life expectancy can be increased 66.7% ~ 79.6%. Figure 3 Figure, Table 3, 5 references.
