Decarburization deteriorates the surface mechanical properties of steel. It refers to the loss of carbon from steel's surface when exposed to an open-air environment in elevated-temperature conditions. Despite the short interaction time and fast thermal cycle of the laser surface-hardening process, decarburization may still occur. This paper …

In this paper, low-energy proton irradiation experiments with different cumulative fluences were performed on samples of AISI 420 stainless steel that were either annealed or tempered at 600 or 700 C.

The loading–unloading curves for the AISI 420 steel normalized at 975 (a), 1025 (b), and 1075 C (c) followed by annealing at 250, 350, 450, 550, and 650 C. between 250 and 450 C heat treatment temperatures, sharply dropped, and eventually stabilized.

Figure 2 (a) shows the XRD patterns of AISI 420 specimens nitrided at different temperatures. It can be seen that no precipitation of CrN phase was found in all specimens. The XRD patterns of the untreated specimen shows the standard α′ phase peaks (JCPDS file 44–1292). phase peaks (JCPDS file 44–1292).
