Most aluminum alloy castings require a thermal processing stage to provide the requisite mechanical properties and dimensional stability. Thermal processing also has a significant impact on machining characteristics, ensuring that casting sections to be machined are not too brittle (causing excessive tool wear), or too soft (tool metal buildup and larger burrs).

This presentation will demonstrate how a novel development of the heat treat process will better assess the effective age temperature on yield strength, ultimate tensile strength, plastic elongation and engine block crack susceptibility during cryogenic cycling. Critical to this study is also understanding the furnaces performance characteristics in terms of temperature gradients and the use of the Thermal Uniformity Survey (TUS) concept as outlined by the CQI-9 protocol.
