HEAs crystallizing in the fcc structure are mainly composed of the late 3d elements (LTM-HEAs), whereas HEAs consisting of the early (refractory) transition elements and the LTM-HEAs containing an increased level of bcc stabilizer form the bcc structure. Guided by the solid solution theory, we investigate the structure and hardness of HEAs as a function of the valence electron concentration (VEC) and the atomic size difference (δ). The fcc structure is found for VEC between 7.80 and 9.50, whereas the structure is bcc for VEC between 4.33 and 7.55. High strength is obtained for an average valence electron number VEC ∼ 6.80 and for an average atomic size difference δ ≈ 6%. Based on these empirical correlations, one can design the high-entropy alloys with desired hardness.}, year = {2015}, eissn = {1879-0216}, pages = {1-6} } @article{MTMT:1344187, title = {An Absolute Scale for the Cohesion Energy of Pure Metals}, url = {https://m2.mtmt.hu/api/publication/1344187}, author = {Kaptay, György and Csicsovszki, G and Yaghmaee, M S}, doi = {10.4028/www.scientific.net/MSF.414-415.235}, journal-iso = {MATER SCI FORUM}, journal = {MATERIALS SCIENCE FORUM}, volume = {414-415}, unique-id = {1344187}, issn = {0255-5476}, year = {2003}, eissn = {1662-9752}, pages = {235-240}, orcid-numbers = {Kaptay, György/0000-0003-4419-142X} }
