| Abstract Scope |
The thermal behavior of the vacuum arc remelting (VAR) process strongly influences solidification phenomena that impact ingot defects, yields, and material performance. For chemistry sensitive alloys, like Nitinol, understanding the composition redistribution induced by the thermal conditions during the VAR process is of the utmost importance. To better understand the energy balance of the VAR process, a series of thermocouple arrays were installed in the sidewall of the copper crucible. The arrays were placed at four different heights in order to measure the temperature changes during the various VAR process regimes. Each array consisted of four thermocouples, equally spaced to allow for both a one- and two-dimensional inverse heat conduction calculation to estimate the heat flux through the copper mold. Comparisons between different inverse models and the uncertainty of the newly found thermal boundary conditions are discussed. |
