Heat treatment is a common practice to achieve higher mechanical properties in the component not reached
during the casting process. Typical Heat treatment involves heating and cooling a casting after shakeout/
ejection. Most heat treatment processes aim to 1) alleviate residual stresses left over from the casting process
and 2) Improve the mechanical properties (e.g., Tensile Strength, Elongation, Hardness, Etc.) of the casting.
Often, with complex castings, the component is placed on a rack of fixtures for part or all of the heat treatment
processes to hold the casting in place, avoiding the formation of defects like distortion and cracking as the
casting responds to thermal changes. The following study evaluated the impact of this support structure’s
design on the final casting quality.
