#0183;#32;A powder of equiatomic CuCrFeTiNi highentropy alloy (HEA) was prepared by shortterm (30 min) highenergy ball milling (HEBM). Our structural and chemical analysis showed that micron sized particles of bcc CuCrFeTiNi consisting of nanosized crystalline grains (6 nm) could be obtained after 30 min of HEBM. The influence of milling time (30 #247; 240 min) on structural and magnetic
#0183;#32;Powders of highentropy Hf Ta Ti Nb Zr C (HEC Zr) and Hf Ta Ti Nb Mo C (HEC Mo) carbides were fabricated through the reactive highenergy ball milling (RHEBM) of metal and graphite was found that 60 min of RHEBM is adequate to achieve a full conversion of the initial precursors into a FCC solid solution for both compositions.
#0183;#32;Because severe deformation (high energy ball milling) leads to high density of dislocations and cavities in nanocrystalline high entropy alloy particles (Fig. 6(b)), there are no obvious orientation relationship between the HEA particles and interfacial layer (shown in inserted figure in Fig. 12(d)) in the 6061AlHEA40 composite.

Highentropy alloys (HEAs) are alloys that are formed by mixing equal or relatively large proportions of (usually) five or more to the synthesis of these substances, typical metal alloys comprised one or two major components with smaller amounts of other elements. For example, additional elements can be added to iron to improve its properties, thereby creating an iron based
