Ajuste de los aceros corrugados ferríticos, austeníticos y austenoferríticos a los modelos de endureci-miento elastoplástico por deformación. Uno de los principales factores tenidos en cuenta en la fabricación de aceros estructurales es su comportamiento durante la fase elastoplástica o de endurecimiento por deformación. Normas neozelandesas y...

The typical distribution of steel used in developed countries, according to World Steel Association, attributes approximately 35% of total steel production in the world to the construction sector. Rebar steel consumption constitutes a significant proportion of that figure. More in-depth knowledge regarding the behaviour of steels used in the...

The calculation of the true stress and strain values during the tensile test necking phase of smooth ductile metals specimens has been extensively pursued by several authors. A symmetrical neck profile, which leads to axial-symmetrical behaviour, is usually considered. In this study, the neck geometry of Temp-core ribbed bars, the most commonly...

Tensile behaviour of metals beyond the ultimate tensile strength (UTS) must be considered to calculate toughness or absorbed energy till fracture. Structural steels, designed to withstand earthquakes, are the typical material where post necking behaviour can be of paramount importance. This paper deals with the tensile stress-strain behaviour...

This work explores the feasibility of recovering antimony, present in a side stream of hydrochloric acid resulting from a copper electro-refining process, by hydrolysis with water. A range of variables that can affect the process have been studied. According to the results, under optimal conditions (pH = 0.645 T = 34 °C), antimony extraction...
