Microstructural Effect on the SCC Susceptibility of Type 316 (LC) Stainless Steel

Mechanism of SCC on SUS310S Stainless Steel

The author have developed a new SCC test method that enables the super Kelvin force microscope (SKFM) and the Kelvin force microscope (KFM) observations. By using this test device, the crack tip deformation and surface potential distribution were observed on SUS310S stainless steel by SKFM and KFM. At the same time, the distribution of hydrogen was examined by the Ag decoration method with the ...

The adhesion of hot-filament CVD diamond films on AISI type 316 austenitic stainless steel

Steel ball indentation and scratch adhesion testing of hot filament chemical vapour deposited diamond films onto AISI type 316 austenitic stainless steel substrates using two different interlayer systems, namely chromium nitride and borided steel, have been investigated. In order to compare the adhesion of these films with that of a well-known and strongly adherent system, detailed adhesion tes...

The combined effect of molybdenum and nitrogen on the fatigued microstructure of 316 type austenitic stainless steel

Introduction The mechanical properties of austenitic stainless steels, including the low cyclic fatigue behavior have been a subject of numerous studies [1-8]. Nitrogen addition, in general, increases the fatigue strength by decreasing the stacking fault energy of austenitic stainless steels [6]. The stacking fault energy has a strong influence on the cross slip difficulty, thus it affects the ...

The Unified Creep-Fatigue Equation for Stainless Steel 316

Background—The creep-fatigue properties of stainless steel 316 are of interest because of the wide use of this material in demanding service environments, such as the nuclear industry. Need—A number of models exist to describe creep-fatigue behaviours, but they are limited by the need to obtain specialized coefficients from a large number of experiments, which are time-consuming and expensive. ...
