Computer Simulation of Immersion Quenching of Uranium-0.75 Wt % Titanium Alloy Cylinders

摘要

It is found feasible for the analytical simulation of the complex quenching process of the U-0.75 Ti alloy. The models developed can be used as a basis to understand, study, and optimize the process. Information obtained from these models can be used to analytically predict temperature distribution, cooling rates, stresses, deformation, phase composition, and possibly void formations, all as functions of both position and time. Nonsymmetrical boundary conditions were demonstrated to lead to bowing of the cylinder, and applicable techniques were developed to optimize the quenching process. Experiments for deriving physical and mechanical properties for the U-0.75 Ti alloy, including data on the heats of transformation were performed. The boundary heat-transfer coefficient is an important factor, affecting both the thermal and the metallurgical behavior during quenching. (ERA citation 11:038302)
