用双辊连续铸轧方法制备了Al Pb系轴瓦合金板材 ,铸轧工艺过程稳定 ,合金板成形良好。金相观察表明 :铸轧合金板第二相分布均匀、细小 ,尺寸 <5 μm ;基体组织形态良好 ,满足轴瓦合金要求。
Al Pb-based bearing alloy sheets were prepared by two-roll continuous casting method. The casting process was stable and the forming of alloy plates was good. Metallographic observation shows that the second phase of the cast-rolled alloy plate is distributed uniformly and finely and the size is less than 5 μm. The matrix microstructure is well-shaped and meets the requirements of the bearing alloy.
