Effect of Grain Size and Deformation Temperature on Mechanical Properties and Failure Behaviour of 316L Austenitic Stainless Steel

Abstract: In this work, the effects of grain size and deformation temperature on mechanical properties and failure behaviour of 316L austenitic stainless steel (ASS) are investigated. The cold, warm and hot deformation are carried out at temperatures of 25, 500, and 800°C for the strain rate of 1⋅10 −3 s −1 . The results show that strength and workhardening index of all samples decrease with increasing test temperature; however, decrement in strength and workhardening index is more less in coarse grained samples compare… Show more

“…The samples were manufactured in the vertical orientation with layers perpendicular to the axis of loading, which contributed to the relatively low tensile strength since most studies report the highest tensile strength is achieved in a horizontal print orientation [14,19]. The average grain size measurements recorded in this study are equivocated by existing literature, which all report grain sizes in the 5-57 𝜇𝑚 range for TM 316 stainless depending on heat treatment [20,21] and 10-50 𝜇𝑚 range for AM 316L stainless steel [22].…”
