The work reported in this paper outlines the use of a combined artificial neural network model capable of fast online prediction of textures in low and extra low carbon steels. We approach the problem by a Bayesian framework neural network model that take into account as input to the model the influence of 23 parameters describing chemical composition, and thermomechanical processes such as aus...

A series of 18 Ni (300 grade) maraging steels of overall commercial purity but containing also deliberate impurity additions of sulphur, phosphorus, carbon, chromium and silicon + manganese has been studied. The fracture toughness and stress-corrosion resistance (determined using planestrain fatigue-precracked specimens tested in 3. 5% sodium chloride solution) of these steels have been compare...

the quenching and partitioning (q&p;) process is a new heat treatment cycle to produce the third generation of advanced high strength steels based on diffusion of carbon from martensite to retained austenite phase. the application of this process for various steels leads to a remarkable combination of mechanical properties including high strength and good ductility. using this process in automo...

In this work, three low-carbon bainitic steels, with different Mo contents, were designed to investigate the effects of Mo addition on microstructure and mechanical properties. Two-step cooling, i.e., initial accelerated cooling and subsequent slow cooling, was used to obtain the desired bainite microstructure. The results show that the product of strength and elongation first increases and the...

Low carbon steels are widely used for structural applications because of its ease in fabrication and the moderate strength it posses. However, its pure corrosion resistance at normal atmosphere is a matter of serious concern.

Hydrogen sulfide (H$) has long been associated with the cause of corrosion damage and sulfide stress cracking (SSC) in high strength steels and high hardness weldments used in oil and gas production, petroleum refining, and petrochemical/chemical processing. Other applications where sulfide species have produced environmental cracking include heavy water production, electric power, marine appli...

Carbonitriding of four types of steels, namely, low carbon steel (LCS), medium carbon steel (MCS), low alloy steel (LAS) and high alloy steel (HAS) was achieved using cyanide salt bath heat treatment process. The steels, after preheating, were heated in a diesel fired salt bath heat treatment furnace and then quickly quenched in different media including air, oil and brine. The heat treatment p...
