Constitutive micromechanical behavior of transformation induced plasticity (TRIP) stainless steel (SS) alloys was investigated using high-energy synchrotron x-ray diffraction (S-XRD) and in-situ neutron techniques. First, four different were designed produced: (1) a metastable austenitic TRIP SS, (2) stable which is counterpart the (3) lean duplex SS with ferrite austenite phases, (4) SS. Then,...

The adoption of the ultrafast heating (UFH) process has gained much attention in last few years, as green energy and minimization CO2 emissions are main aspects contemporary metal science thermal treatment. effect treatment on carbon steels, non-oriented grain (NGO) electrical ferriticor austenitic stainless steels is reported this review. study highlights ultrarapid annealing microstructure te...

During ageing, the ferritic phase of Cast Austenitic Stainless Steels (CASS) undergoes decomposition by spinodal and G-phase precipitation, which leads to increasing hardness decreasing impact toughness. Mo-bearing steels are more prone ageing than Mo-free steels. To study effects Ni, Mo, Mn, duplex model alloys were thermally aged at 350 °C 400 °C. The microstructure evolution during was chara...

The purpose of the research: evaluation quality and durability for pipes made high-alloyed austenitic ferritic-austenitic steels, which are manufactured at PJSC "CENTRAVIS PRODUCTION UKRAINE" using latest technologies, by conducting complex laboratory studies long-term operational tests chemical industry enterprises. Materials methods: research materials were experimental chromium-nickel-molybd...

The load partitioning between the two phases in a cold rolled duplex stainless steel sheet have been experimentally studied in situ during loading, via X-ray diffraction, for different loading directions. The microstresses in the two phases were found to decrease when loading in the transverse direction, while they increase during loading in the rolling and 45°-direction. Due to strong crystall...

Ferritic–austenitic duplex stainless steels are known to offer favorable combinations of good mechanical properties and corrosion resistance be used for structural purposes. Lean grades have already been introduced consideration replace standard 18–8 austenitic in various industrial applications. Ferrite austenite represent different deformation behaviors contribute the resulting fracture tough...

A patient who recently came under my care had been struck in the right eye by a foreign body whilst hammering a piece of steel with hammer and cold chisel. A diagnosis of intra-ocular foreign body was made, there being a small entrance wound in the centre of the cornea and an opaque lens. This diagnosis was confirmed by x ray. The foreign body, measuring about 3j x 1 x 1 mm. was located in the ...

Point defect species and concentrations in metastable Fe-C alloys are determined using density functional theory and a constrained free-energy functional. Carbon interstitials dominate unless iron vacancies are in significant excess, whereas excess carbon causes greatly enhanced vacancy concentration. Our predictions are amenable to experimental verification; they provide a baseline for rationa...
