Introduction

In studying High Entropy Alloys (HEA), complexity becomes a limiting factor for pure empirical research. In order to combat this, CALPHAD has been used to calculate and predict new interesting compositions to then deposit and study. However, this work has only been limited to macroscale approaches, with also seeing limited use for magnetron sputtered samples. This assignment looks into the calculation of new interesting alloys with a.o. CALPHAD software, which are then deposited in our labs and tested. The goal is to increase understanding in what factors play a role in specific properties, as well as the accuracy of using CALPHAD in informing new material depositions.
