Three series of two types of specimens were cast from a cobalt and a nickel base alloy using variation in mould and metal temperatures and in mould size. The casting procedures included a unidirectional solidification system and a problem of feeding. Porosity was assessed by radiographic and metallographic analyses.
使用不同的模具温度、金属温度和模具尺寸,从钴基合金和镍基合金中浇铸出了三组两种类型的试样。铸造工艺包括单向凝固系统和补缩问题。通过射线照相和金相分析对孔隙率进行评估。
