High entropy multicomponent WMoNbZrV alloy processed by mechanical alloying

The aim of this work was to apply mechanical alloying technique for synthesis of high entropy multicomponent equimolar WMoNbZrV alloy and to investigate the phase composition after milling and after heat treatment, as well as to characterize the observed changes of crystallite size, lattice strain and lattice parameter of solid solution formed. It was found that nanocrystalline bcc solid solution was characterized by crystallite size of 10 nm, lattice strain of 0.58% and lattice parameter of 3.1687 angstrom. Heating the sample up to 700 degrees C resulted in decrease of lattice strain down to 0.20%, while the crystallite size remained not changed, testifying good thermal stability of nanocrystalline bcc solid solution obtained.
