The Avitzur's limit analysis for the calculation of the drawing force in a wire drawing process is used to study the real behaviour of a carbon steel in an industrial case. The linear hardening assumption, used by Avitzur only for the first step, is

The cold wiredrawing process constitutes a classical-tribological system in which a stationary tribe-element (die) is in contact with a tribe-element in relative motion (wire) and both interacting with the interfacial tribe-element (lubricant). This

Microstructure, hardness, transverse rupture strength, and abrasion resistance of WC-10 wt% Co cemented carbides modified with the addition of different mass fraction of Cr3C2, in the range of 0⁻3 wt%, are studied. The influence of the microstructu

Tensile properties and fracture location of AA2139-T351 friction stir welded joints are studied in the as-welded and post-weld aged condition. The experimental results show that when the joints are free of welding defects, they fail on the advancing

The effect of heat input rate, hatch spacing, and focus offset upon microstructure, hardness, and roughness of EBM-manufactured Ti- 6Al-4V titanium alloy was studied via a factorial experiment. It had been found that a coarser microstructure is gener
