Tensile mechanical properties
Tensile tests were performed using an Instron 8802 instrument on dog bone specimens (Figure S8  supplementary data), respectively, at a strain rate of 0.003 s-1.

Data files description

Txt. file Summary of evaluated values of mechanical properties indicate average values of measured yield strength, ultimate strength and elongation to fracture. Tensile yield strength (TYS0,2 in MPa), Ultimate tensile strength (UTS in MPa) and elongation to fracture (E in %) are dysplayed. 

Other txt. files represents data of tensile curves of materials of specific chemical composition in at. % measured at laboratory temperature or at 37 C.
