通过大量的金相观察,找出了用简易小试块来判断大断面的曲轴组织的统计规律.所得结论,不仅适用295柴油机曲轴,对其他类似的球铁铸件,也有参考价值.
Through a large amount of metallographic observation, we find out the statistical law of the crankshaft structure with large and small test pieces to judge the large cross-section. The conclusion is not only applicable to 295 diesel engine crankshaft, but also has reference value for other similar ductile iron castings.
