Tensile properties analysis of AA1100 aluminium and SS400 steel using different JIS tensile standard specimen

Determination of tensile properties of metals or alloys is based on its type and shape which are found to be important aspects. Tensile specimen thickness, width, and rolling force direction affected the tensile properties of conventional metals such as copper sheet. Nevertheless, tensile specimen standards are still not specified yet, especially with regard to advanced materials such as thin wall ductile iron (TWDI). Following the recent findings of large deviations of tensile properties in TWDI plates, this paper describes a study of the effect of specimen width on the tensile properties of aluminium and steel sheets. The purpose of this study was to investigate whether the similar behaviour of tensile properties of TWDI would also occur in other metals. As-received commercial aluminium sheet grade and general structural hot-rolled steel were used for tensile specimen according to standard JIS Z2201 No. 13(b) and 5. The results showed that aluminium was more sensitive to tensile specimen width than compared steel.
