Best Practice : Quench Simulator
The Quench Simulator at Oak Ridge is a computer model developed to simulate the quenching behavior of uranium/titanium alloys. The model is used to predict transient temperature distributions, residual stress profiles, microstructure, mechanical properties, and distortion of the alloy upon quenching and utilize this information to help solve heat treatment problems.
The model incorporates the use of two codes, the thermal analysis code TOPAZ and the stress analysis code NIKE. It requires extensive property characterization of an alloy as a function of temperature and microstructure. Verification studies have been performed and predictions supported through neutron diffraction analysis. In addition to predicting the amount of residual stress upon quenching, verification of components that have undergone stress leveling (1% to 2% permanent set after heat treatment) has been performed.
The Quench Simulator has the proven capability to evaluate material substitution and optimize material performance. It can be used to eliminate costly errors in the production of close tolerance components and is significantly ahead of the current information and models available in industry.
