WebSep 1, 2016 · Axially push-pull fatigue tests of a low-strength Cr-Ni-Mo-V steel welded joint using cross-weld specimens with two types of sampling, i.e., weld metal centered and heat-affected zone centered, were conducted up to 5 × 10 7 cycles at room temperature and 300 °C. Fatigue strength of heat-affected zone centered specimen was higher due to ... WebShinohara et al. [] pointed out that the precipitation of the 𝜎 phase was a diffusion-controlled phase transformation in 25% Cr-20% Ni stainless steel, and that the Cr atom had an important effect on the acceleration of the precipitation rate of the 𝜎 phase.The precipitation rate of the 𝜎 phase in 𝛿-ferrite was higher (by about 100 times) than that of 𝛾-austenite [].

Reduction mechanism of chromite spinel with carbon

WebThe trivalent chromium (Cr) leached from stainless steel slag can be oxidized into hexavalent Cr with strong toxicity in the natural storage process, thus causing severe … WebMar 17, 2024 · In this study, the predominant mechanical properties and deformation mechanisms of CoCrFeNiMn x high entropy alloys (HEAs) were explored by using the molecular dynamics (MD) simulation. A uniaxial tensile process with different temperatures (100–700 K) and compositions of manganese (x = 0, 5, 10 and 20) were conducted. WebThe purpose of this thesis was to present a model for the effects of solute atoms on creep strength of austenitic stainless steel for application in Ultra supercritical boilers. The study materials were including Sanicro 25 and Alloy 316H. In Sanicro 25, the modeling has been done for W-, Nb- and Cr-solutes. masonry wall meaning in hindi
