摘要
用化学成分分析、宏观低倍检验、金相组织分析和渗透探伤等方法对铜合金C19210扁铸锭锯切端面发现的裂纹进行了分析。结果表明:此类裂纹产生于铸造过程中,为铸造应力造成的热裂纹,对裂纹产生的原因进行了分析,并提出了预防措施。
The end surface cracks on C19210 flat ingot casting are analyzed using chemical composition analysis,macroscopic examination,microstructure examination and penetrant testing in this paper.The results showed that this kind of cracks produced in the casting process,were the heat cracks,had the reason to the cracks to carry on the analysis,and proposed the preventive measure.
