SIMULATION OF THE MICROSTRUCTURE DISTRIBUTION OF HYDROGEN STORAGE ALLOY AND OPTIMAL DESIGN OF CASTING MOULDS

Abstract

Abstract: In this paper,a simulation model for the temperature field in the solidification process and microstructure distribution is presented. Then, the result of simulation for the final microstructure distribution is compared with experiment using 10-Kg ingot of MlNi3.55Al0.3Mn0.4CO0.75 (Ml: Lanthanum-rich Mischmetal) hydrogen stor- age alloy cast in a mould, which agrees with the experiment well. Finally, in order to obtain the expected as-cast microstructure distribution of 15-Kg ingot of MlNi3.55Al0.3Mn0.4Co0.75 alloy, the size of Cu mould is optimized using the model described. The optimized mould is then made and the alloy is cast in it, the expected as-cast microstructure distribution is obtained.

Key words: hydrogen storage alloy, microstructure, simulation, casting
