带状组织对锰基锰铜合金加工性能的影响

Effect of Banding Structure on the Mechanical Properties of Manganese Copper Alloy

锰基锰铜合金在热（冷）加工时表面出现开裂现象。通过金相分析的方法观察到该合金的开裂现象系由带状组织的存在所致。带状组织在材料的锻态、热轧态、冷轧态及复合态时均有存在。带状组织的存在导致材料的力学性能下降，是该类合金在加工过程中开裂的原因之一。

Metallographic analysis showed that banding structure led to the formation of cracking in manganese copper alloy during the hot and cold working. Banding structure was found in forged, hot rolled and cold rolled materials. The banding structure will led to decrease of the mechanical properties of the material and led to the formation of cracking.
