Abstract

Differential thermal analysis on metallic alloys containing volatile elements can be highly problematic. Here we show how measurements can be performed in commercial, small-sample equipment without modification. This is achieved by using a sealed Ta crucible, easily fabricated from Ta tubing and sealed in a standard arc furnace. The crucible performance is demonstrated by measurements on a mixture of Mg and MgB2, after heating up to 1470°C. We also show data, measured on an alloy with composition Gd40Mg60, that clearly show both the liquidus and a peritectic and are consistent with published phase-diagram data.
