A 0.4C-2Si-1Cr-1Mo steel with an ultrafine elongated grain (UFEG) structure and an ultrafine equiaxed grain (UFG) structure was fabricated by multipass caliber rolling at 773 K and subsequent annealing at 973 K. A static three-point bending test was conducted at ambient temperature and at 77 K. The strength-toughness balance of the developed steels was markedly better than that of conventionall...

Recent advancements in metal fibers have introduced a promising new type of stainless steel fiber with high stiffness, high failure strain, and a thickness < 100 μm (<0.00394 in.) that can be utilized in a steel fiber-reinforced polymer. However, stainless steel is known to be susceptible to pitting corrosion. The main goal of this study is to compare the impact of corrosion on the mechanical p...

The aim of this paper was to study the effects of die life through shot peening treatments on AISI H13 steel, and tests were performed to study the influential parameters of the shot peening process. To evaluate the effects of microstructure and the die life of AISI H13 steel after steel shot peening processes, we conducted and evaluated roughness tests, micro hardness and wear tests, and SEM m...

This paper presents a finite element analysis on the tensile stiffness of steel bolted connections, which are fabricated from thin-walled cold-formed steel strips and members. This type of bolted connection is usually used to assemble the diagonal bracing member in the light steel structure. Unlike the architectural steel structure, thin walled steel bolted connection cannot be simplified into ...

This paper demonstrates the integration of Mathcad programming in a steel design course at the University of Qatar. It discusses the advantages of Mathcad programming over other programming formats and provides guidelines to incorporate Mathcad programming into the steel design course. A Mathcad program for the analysis and design of steel beams is presented to show the attractive computational...

This paper is concerned with the inelastic behavior of axially loaded concrete-filled thin-walled steel tubular columns subjected to local buckling. A nonlinear fiber element analysis program accounting for local buckling effects is developed for predicting the ultimate strength and ductility of concrete-filled thin-walled steel tubular columns. The effects of local buckling are taken into cons...

Based on the National Bureau of Standards [presently called The National Institute of Standards and Technology or “NIST”] statistical data on corrosion of steel, an equation is introduced to estimate the corrosion rate of underground steel. The variables include the major soil characteristics (parameters), namely: resistivity, pH value, moisture content and aeration. This formula, together with...

The Steel Founders’ Society regularly surveys member companies to determine the typical practices used in steel casting production. SFSA has also promoted the participation of member companies in the Performance Benchmarking survey available each year to members of participating manufacturing associations. It is useful to take a look across the results of the past several years and to reflect o...

K. Nowacki, P. Musiał, T. Lis Silesian University of Technology, Department of Metallurgy, Katowice, Poland Acoustic steel processing in an ingot mould may be the fi nal stage in the process of quality improvement of a steel ingot. The impact of radiation and cavitation pressure as well as the phenomena related to the acoustic wave being emitted and delivered to liquid steel aff ect various asp...

The fellow and I then went to see the patient. The man looked about 60 years old but had the frail appearance of someone who had suffered rheumatoid arthritis (RA) for many years. For whatever reason, he had missed out on modern aggressive therapy, the target never hit or perhaps even aimed at. His fingers were angulated and there were nodules on top of his knuckles. At the juncture of a few of...
