Abstract

This work employs a novel, small-scale rapid alloy prototyping (RAP) method, developed throughout the project, to investigate the feasibility of using this research method to investigate the effects of residual elements. The RAP samples vary from 20g to 140g and are quick to produce, allowing an arr...
