摘要
Using direct finite difference method, a numerical model for simulating the temperature field in the charge during induction skull melting (ISM) has been developed. On the basis of the model, the temperature field in Ti- 47Ni-9Nb ingot has been calculated under various melting conditions. Finally, the processing parameters (melting power, melting-down time and the final melt temperature) have been optimized.
