In the present study, a constitutive analysis of the evolution of the mechanical response of a CrN/NbN superlattice coating exposed to high temperature has been performed. Parametric approaches were used to obtain a single ...
Mechanical and microstructure characterization of hard nanostructured N-bearing thin coating

Tools for machining are made of hard steels and cemented carbide (WC-Co). For specialized applications, such as aluminium machining, diamond or polycrystalline cubic boron nitride are also used. The main problem with ...
Modelling of the flow behaviour of wrought aluminium alloys at elevated temperatures by a new constitutive equation

El Mehtedi, M.; Musharavati, F.; Spigarelli, S. ( Elsevier, Ltd , 2014 , Article)
The hot working behaviour of an Al–0.7%Mg–0.4%Si (wt.%) aluminium alloy has been investigated by torsion testing in the 450–575°C temperature range. The behaviour of the alloy, in terms of equivalent stress vs equivalent ...
