High entropy alloys, HEAs, have expanded the compositional spaces of modern metallurgy into highly concentrated and chemically complex alloys, previously believed to be unproductive. With this newfound compositional freedom, comes additional control, allowing for new investigations into previously established mechanisms. To discover new and potentially useful alloys, the HEA field is continually expanding away from the equiatomic solid solutions that dominated early work. The work presented in this dissertation utilizes two, intuitive, pseudo-binary HEA systems to investigate compositional effects on solid solution strengthening in highly concentrated alloys and twinning and transformation induced plasticity. It furthers the understanding of the mechanical properties of concentrated alloys and their deformation mechanisms.
