This study investigates the mechanical properties of partially and fully recrystallized Ta-10W alloy tubes through Vickers hardness measurements and tensile testing, employing the Digital Image Correlation (DIC) technique. The hardness and tensile behavior were analyzed with respect to positional variations along both the thickness and circumferential directions. Partially recrystallized Tube A exhibited a non-uniform hardness distribution, whereas fully recrystallized Tube B demonstrated uniform hardness. Tensile tests revealed yield point elongation (YPE) in both samples, although no localized deformation zones (Lüders bands) were observed in the strain distribution maps. A linear correlation between Vickers hardness and yield strength was confirmed, with an accuracy of 90.1%. The Swift non-linear hardening equation was applied to precisely determine the hardening coefficient (k), hardening exponent (n), and initial strain (ε₀). This approach provides an effective method for predicting the mechanical properties of Ta-10W alloy based on hardness data under room temperature and quasi-static conditions. Consequently, this study offers essential foundational data for predicting the mechanical properties of Ta-10W alloy.
