| Abstract Scope |
Multi-principal element alloys (MPEAs) such as high-entropy alloys hold great potential for application due to their unique properties. Face centered cubic (FCC) transition metal MPEAs in particular are known for their exceptional toughness and ultimate tensile strengths. Their yield strengths tend to be unremarkable, however, especially when they are produced via traditional casting and hot-rolling processes. In this work, we describe the strengthening of hot-rolled CrMnFeNi-type MPEAs through the precipitation of vanadium carbide (VC) and chromium carbide nanoparticles. We will discuss the effects of rolling parameters and heat treatment on microstructural outcomes such as grain size and hardness, as well as tensile test results for material subjected to optimized heat treatment. Carbide-free analogs of the same alloys prepared and tested under identical conditions reveal the impact of nanoprecipitate formation. |
