“…Nucleation of fatigue cracks in the untreated specimens occurred at the surface, while for carburized samples occurred near the boundary between the carburized layer and the substrate, regardless of the applied stress level. With tension-compression fatigue tests [205], carried out on gas carburized (470 • C, 30 h) AISI 316L specimens, the fatigue strength was increased up to 275 MPa for carburized specimens, a 22% improvement in comparison with the untreated alloy, which showed an endurance limit of 225 MPa. Crack initiation sites depended on the applied stresses.…”

Austenitic stainless steels are employed in many industrial fields, due to their excellent corrosion resistance, easy formability and weldability. However, their low hardness, poor tribological properties and the possibility of localized corrosion in specific environments may limit their use. Conventional thermochemical surface treatments, such as nitriding or carburizing, are able to enhance surface hardness, but at the expense of corrosion resistance, owing to the formation of chromium-containing precipitates. An effective alternative is the so called low temperature treatments, which are performed with nitrogen- and/or carbon-containing media at temperatures, at which chromium mobility is low and the formation of precipitates is hindered. As a consequence, interstitial atoms are retained in solid solution in austenite, and a metastable supersaturated phase forms, named expanded austenite or S phase. Since the first studies, dating 1980s, the S phase has demonstrated to have high hardness and good corrosion resistance, but also other interesting properties and an elusive structure. In this review the main studies on the formation and characteristics of S phase are summarized and the results of the more recent research are also discussed. Together with mechanical, fatigue, tribological and corrosion resistance properties of this phase, electric and magnetic properties, wettability and biocompatibility are overviewed.

“…Regarding this work, the corrosion fatigue cracking mechanism is discussed. In SS 316L, the influence of low temperature has been investigated and the result shows that the SS 316L has 22% higher endurance compared to untreated SS 316L [34]. In this experiment, the SS 316L has undergone several tests and it is concluded that the fatigue crack propagation is enhanced by carburized material at high-level stress with the ductility of 10µm.…”

Corrosion is a destructive process that converts the pure metal into a chemically stabled form by hydroxide or sulphide and it is a slow process of destruction on the material by the chemical or electrochemical reaction in the environmental space. This kind of destruction has been typically produced from oxides or salt content on the material and it results in distinctive orange coloration. The classifications of corrosion act on atmospheric air and liquids as well as on contact of two solids. To resist the corrosion rate, stainless steel 316 has been chosen because of the presence of 2-3% molybdenum content and the presence of molybdenum plays a vital role in corrosion resistance. In this study, literature related to various works has been reviewed to explain the corrosion behaviour on cavitation, crevice, electrochemical, erosion, fatigue, galvanic, uniform, pitting, and stress corrosion which act on 316 stainless steel. In the present work, several coating processes and the additives, that have been added to SS 316 to enhance the outcomes according to various corrosion causes, are discussed.

“…Generally, the uniaxial tensile test or bending fatigue test is used to study carburized steel's fatigue properties [6,7,13,[22][23][24] . The fracture morphology of the impact piston is the same as that of carburized steel.…”
