Curtin (2020) Acta Materialia 182, 235-249 % To access the data, >> load DATA_10mln_STRENGTHS.mat from the MATLAB command line. 1. The array Data_strengthT sorts compositions from lowest to highest T=1300K yield strength. Each row of the array refers to one composition. The first 10 columns indicate the elemental composition as follows: Col. 1: Nb Col. 2: Mo Col. 3: Ta Col. 4: W Col. 5: V Col. 6: Cr Col. 7: Ti Col. 8: Zr Col. 9: Hf Col. 10: Al Columns 11 to 15 store output calculated with the BCC edge theory: Col. 11: T=0K yield strength, sigma_y0 = tau_y0*TF [GPa] Col. 12: T=0K specific yield strength, sigma_y0/rho [GPa * cm^3 / g] Col. 13: T=0K energy barrier, DE_b [eV] Col. 14: T=1300K yield strength, sigma_y = tau_y*TF [GPa] Col. 15: T=1300K specific yield strength, sigma_y/rho [GPa * cm^3 / g] Where: tau_y0 = T=0K critical resolved shear stress; tau_y = finite T critical resolved shear stress; rho = alloy density; TF = 3.067 Taylor factor for BCC. 2. The array Data_strengthweightT sorts compositions from lowest to highest T=1300K specific strength (yield strength / alloy density). The data stored in the columns is exactly the same as in (1).
