The effect of variation in mould temperature, metal temperature and mould size on the development of internal porosity in cast structures.
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.
