Vacuum induction melting (VIM) is the most widely used process for the commercial production of NiTi alloys. But, the major drawback in VIM is the carbon contamination of the ingot from the graphite crucible. During melting, carbon reacts with Ti and forms TiC. This alters the Ni/Ti ratio in the all
## Abstract The present work studies the performance of three different kinds of commercial crucible graphite materials used during inductive melting of NiTiβshape memory alloys (SMAs). One lowβdensity extruded graphite and two isostatically pressed graphiteβmaterials with different porosity and p
