Formation of unwanted deposits on steels during their interaction with liquids is an inherent problem that often leads to corrosion, biofouling and results in reduction in durability and function. Here we report a new route to form anti-fouling steel surfaces by electrodeposition of nanoporous tungsten oxide (TO) films. TO-modified steels are as mechanically durable as bare steel and highly tol...

In the frontier of materials science, understanding of materials has been in multiple scales from macro, micro, to atomic levels. This is attributed to the advanced instrumentations such as SEM, TEM, XPS, XRD, as well as several other spectroscopic and metallographic analyses. Fe-CrNi based austenitic stainless steels have a diverse range of modern applications ranging from biomedical prosthese...

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...

the effect of ferrite grain size on the fatigue and tensile properties of dual phase steels with a 0.25 volumefraction of martensite (vm) under different heat treatments was investigated. the heat treatments werehomogenized at 1200 oc along with several subsequent normalizations at 910 oc, resulting in differentmicrostructures and mechanical properties. after heat treatment, the obtained steels...

Application of magnetic Barkhausen emission (MBE) analysis for assessment of microstructures and damage in various materials including carbon steel, Cr-Mo ferritic steels, 17-4 PH steel and metastable austenitic stainless steel has been highlighted in this paper. Thermally induced microstructural changes in Cr-Mo steels have been correlated with MBE, based on a two stage magnetization process m...

perature range between 260° and 360°C. Jack showed that thin platelets of cementite formed at the beginning of this stage(10). In high carbon steels, the transformation twin interfaces are potent nucleation sites for the cementite formation and the cementite is related to the ferrite by Bagaryatskii's orientation relationship(2)(3)(11). Although there is no direct evidence of its existence in s...
