Mechanical Response and Failure Evolution of 304L Stainless Steel under the Combined Action of Mechanical Loading and Laser Heating

Abstract: Deformation and fracture properties of structural materials are greatly influenced by the factors like applied load, state of stress, and temperature. A precise prediction of the material properties of stainless steel at elevated temperature is necessary for determining the load-carrying capacity of structures under severe conditions. The present work reports the deformation and failure characteristics of 304L stainless steel subjected to combined laser heating and mechanical loading. The effect of main parame… Show more

“…According to solution strengthening mechanism, III alloy with high concentration of solution atoms has higher hardness. At the early aging stage, the alloy hardness increases rapidly, which is attributed to the amplitude modulation decomposition transformation and the continuous precipitation of ordered phase [32][33][34]. It is well known that the hardness of Cu-15Ni-8Sn alloy will decrease significantly after a long time of aging, which is caused by DP [12].…”

“…The microstructure and the hardness change from the base metal to the fusion zone, i.e., the microstructure of the nearest subzone to the FZ has the lowest hardness and the highest grains size; however the nearest subzone to the BM has the highest hardness and the lowest grains size. Jelani et al [19] concluded that the sensitivity of the mechanical properties of 304L stainless steel to temperature, i.e., the material becomes softer and more ductile with the increase of the temperature up to 900 °C. For this reason, the nearest subzone to the FZ has the lowest hardness.…”

“…However, as austenitic stainless steel, the low hardness and poor wear resistance of 316L stainless steel limit its wider application [4][5][6][7]. Surface strengthening techniques such as carburizing, nitriding, local heat treatment, and shot peening have been employed in practical applications to improve the surface properties of 316L steel [8,9]. Zhou et al [10] investigated the effect of shot peening intensity on the surface integrity and fatigue life of 316L stainless steel.…”
