EMAT 544 - Casting & Solidification

3 credits (Hrs: 3 Lec.)

Theory of solidification is reviewed including heat flow, nucleation and growth kinetics, solute distribution, constitutional undercooling, and grain and sub-grain structure. Both micro and macro forms of segregation are examined. Different casting methods and molding materials are characterized and compared. Casting concerns and special handling techniques for particular alloys systems are discussed. Methodologies for mold design are covered. Feeding, gating and risering systems are studied with the aid of fluid dynamics. Models regarding the formation of casting defects, porosity and hot-tearing, are outlined. Student must prepare an extensive literature review on a select topic.

Prerequisite(s): Senior or Graduate Standing and Consent. Course generally offered 1st semester of odd numbered years.
