- 摘要:
- 采用宏观检验、微观检验等手段,对2A12壳体固溶处理时产生的裂纹进行分析。结果表明,显微组织中大量的复熔球、三角晶界及晶界熔化现象,是壳体固溶处理时严重的过烧特征,也是导致壳体产生裂纹的主要原因,并提出了改进措施。The cracks of shell 2A12 during solid solution treatment were analyzed by means of macro inspection and micro inspection.The results show that a large number of remelting balls,triangular grain boundary and grain boundary melting in the microstructure are serious overfiring characteristics of shell during solid solution treatment,and are also the main causes of shell cracking and put forward improvement measure.
