The objective of this study was to learn about high entropy alloys, multi-principal element alloys, and refractory alloys, as well as to produce a refractory multi-principal element alloy, NbVZr. This report focuses on the compositional error resulting from sample mass before and after an initial arc melting process. With an expected sample weight of 15.00 g per sample, material was initially measured within an average of 0.036% error. After this initial melting process, mass error increased by 0.030%, resulting in an average error of 0.1201%. This can be attributed to sample vaporization, oxidation, and displacement of small particles. For future alloy production, material placement within the hearth can be considered to avoid material vaporization for more accurate atomic equilibrium concentrations.
