High entropy alloys have shown promise through their ability to be tailored to specific scenarios. From highly corrosive environments to precipitation strengthened alloys to radiation environments high entropy alloys allow tailor made alloys for every solution. New compositions are developed and tested but little work focuses on the processing effect choosing rather than using processing as a stepping stone to achieve properties without investigating the processing effects. This work focuses on single phase face-centered cubic alloys strengthened by processing and precipitation strengthening. In conjunction with the development of these alloys, the ability to scale production will be investigated and characterized to determine major hurdles for future work. FeNiMn30Cr10, FeNiMn20Cr20, FeNiMn20Cr20 Ti2Al1 and FeNiMn20Cr20 Ti1Al3 are investigated for their mechanical properties, their precipitation behavior where applicable, and the effects of various processes on each of the alloys to improve performance or understand potential future pitfalls for production. FeNiMn20Cr20 Ti1Al3 was found to have the most favorable properties with a peak aged strength of 890 MPa at an elongation of 45%. The process of casting this alloy in a small scale foundry was investigated and the effect of contaminates in the form of inclusions were also looked at. It was determined that the different processing steps are such as homogenization and even aging are vital for inclusion elimination.
