"Semi-solid metal (SSM) processing has emerged as a preferred manufacturing method due to the superior quality associated with semi-solid castings. In recent years, the driving force to reduce process cost has led to the development of a few rheocasting (also termed slurry-on-demand) processes. These include UBEâ€™s New Rheocasting (NRC) process , Idra Princeâ€™s Semi-Solid Rheocasting (SSR) process , and THTâ€™s Sub-Liquidus Casting (SLCÂ®) process . A novel slurry-making SSM process developed at ACRC/MPI, termed the â€œContinuous Rheoconversion Processâ€ (CRP), is a passive liquid mixing technique in which the nucleation and growth of the primary phase are controlled using a specially designed â€œreactorâ€. The reactor provides heat extraction, copious nucleation and forced convection during the initial stage of solidification, leading to the formation of thixotropic structures. In these studies, the critical issues/challenges to optimize the CRP for industrial applications have been addressed through validation experiments and pre-industrial trials."
