Estimation of Susceptibility to Hot Tearing in Solidifying Casting

Chapter
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 170)

Abstract

Hot tearing, also called hot cracking, is a serious defect that appears during the solidification of an alloy. Due to the low recurrence of the phenomena occurring during alloy solidification, such as the evolution of grained structure or stress redistributions, the casting’s susceptibility to hot tearing can be estimated only in an approximate way. Predicting the appearance of hot tears in alloys is thus an important issue in industrial practice. This work concerns with a new criterion for hot tearing evaluation in castings. An algorithm for the computer simulations of the phenomena accompanying the casting formation is introduced and discussed.
