Fracture Modes of AISI Type 302 Stainless Steel Under Metastable Plastic Deformation

Abstract: Martensitic transformation can be induced by plastic deformation in metastable iron-based alloys, such as stainless steels containing limited amounts of C, Ni and Cr. This transformation takes place at the temperature range from M s and M d , usually at relatively lower temperature values. The transformed martensite has been associated with maximum ultimate strength and relatively high ductility. In the present work, the tensile fracture characteristics of a metastable AISI type 302 stainless steel was investi… Show more

“…The appearance of this plateau on the tensile stress-strain curve depends on the chemical composition of the studied austenitic stainless steel, the strain rate, and the temperature of tension. [59][60][61][62] The slowly rising stress range was detected in the literature mainly for 301, 302, and 304 types of stainless steel at tension temperatures lower than À 15°C. [59,61,62] In our case, plateau was not observed on the stress-strain curves which can be attributed to the fact that we studied 316L steel at room temperature.…”

“…The mechanism for the primarily slow strength degradation is the low sensitivity of strengthening species in 304L stainless steel to modest temperature increases. Later, with the further increase in temperature, the strengthening species start to lose coherency, and favor mechanical degradation [23][24][25][26]. When the continually-heated specimen with limited thermally activated dynamics continually attains strain energy from the preload, it eventually becomes energetically supportive, to relieve the load through fractures in the specimen.…”
