Effect of the Geometry of an Ingot on Its Chemical Heterogeneity. Part II*

  • Published:
Metallurgist Aims and scope

Certain tendencies in the axial and radial distributions of segregates in forging ingots are discovered by computer modeling and generalization of data obtained from studying the chemical heterogeneity of such ingots. Recommendations are given on optimizing these ingots’ geometry to minimize the heterogeneity.
