Quality Anomaly Analysis of Ni-Si-Cu Alloy Product
This paper analyzes the reasons for the quality anomalies in non-vacuum melted Ni-Si-Cu alloy products.Through alloy composition analysis,property test,and observation on alloy production site,it was discovered that the total amount of added Ni and Si elements in the alloy is low,and the Ni/Si mass ratio is unsatisfactory,resulting in a lower alloy hardness.In addition,the high content of impurities such as Fe in the alloy reduced electrical conductivity.After imple-menting the improvement measures,both the quality and qualified rate of the produced Ni-Si-Cu alloy products have been greatly improved.
