| Abstract Scope |
High entropy alloys (HEAs) got huge appreciation by metallurgy researchers from last two decades and became focal point displacing steels. Most of the work on HEAs is focused on transition metal-based alloys highlighting the importance of configurational entropy maximization in them, however, lot of debate happened on this and the definition of HEAs evolved with time. This work for the first time uses the configurational randomness in HEA design and applies to more local state of the alloys i.e. phases thereby generating high entropy phases (HEPs) in traditionally defined conventional alloys. These HEPs will have higher configurational entropy and can be in the form of a second phase, matrix phase or precipitate. Thus, alloy (A-B) containing atleast one principle element (A≥70at.%) along with one HEP is thus termed as high entropy conventional alloy (HECA) and this study presents design, processing and properties of Cu-rich HECA as a proof of concept. |
