In the present research, the effect of the homogenization process and annealing temperature were investigated for the 1.4470 ferritic-austenitic stainless steel in the as-cast condition. In this regard, microstructural evolutions, hardness, and impact energy of the steel was evaluated with different heat treatment conditions. The results show that the minimum volume fraction of austenite phase ...

The microstructure of multiphase steels assisted by transformation-induced plasticity consists of grains of retained austenite embedded in a ferrite-based matrix. Upon mechanical loading, retained austenite may transform into martensite, as a result of which plastic deformations are induced in the surrounding phases, i.e., the ferrite-based matrix and the untransformed austenite. In the present...

abstract: the lifetime of a cutting tool is an important and determinant parameter for evaluating its performance. the amount of tool abrasion affects seriously dimensions and surface quality of the working piece so that one of the main factors to determine the lifetime of a tool is the level of its wearing. for this purpose, an abrasion standard is defined for each particular tool above which ...

The design rules for centrically compressed stainless steel equal-leg angle members are not explicitly stated in the current European standard SRPS EN 1993-1-4. This paper summarizes results of extensive research conducted on this type structural elements aiming to define recommendations their design. Based a systematic experimental investigation, detailed numerical analysis was performed, and ...

Supercritical carbon dioxide (S-CO2) has the advantages of amphoteric liquid and gas, which possesses many unique characteristics, such as good compressibility, high density, solubility, fluidity low viscosity. The Brayton cycle with S-CO2 is considered to have promising applications, especially for power conversion industries. However, corrosion degradation structural materials hinder developm...
