This chapter begins with a short overview of the historical development of the ferritic/martensitic steels for nuclear energy systems, followed by a section that outlines the numerous nuclear applications where this type of steels are currently used or for ...
Electron microscopy offers a wide range of techniques to study materials. Environmental Scanning Electron Microscopy (ESEM), in particular, allows the characterisation of samples at high-temperature using a laser heating stage, and under various gaseous at ...

The martensitic phase transformation in steel is one of the most famous solid state transformation because of its contribution in the development of the modern industry. This transformation from a face-centered cubic (FCC) high temperature phase, called th ...

A multi-phase Ti-6Al-4V prepared by electron beam melting and thermal post treatments has been shown to exhibit increased strength and ductility over standard wrought or hot isostatic pressed Ti-6-Al-4V. The mechanical improvements are due to a prolonged, ...
Current experimental studies on the seismic behavior of steel wide-flange columns under multi-axis cyclic loading reveal that these members, depending on their geometric characteristics, may be susceptible to axial shortening, out-of-plane deformations and ...
Extreme events often subject regions of structural steel components to large inelastic strains. In conditions such as earthquakes, exceptional winds gusts or tides the loading scenario is cyclical, variable amplitude and frequently multiaxial in nature, an ...
Additive Manufacturing (AM) in whole and especially Selective Laser Melting (SLM) are already making a revolution in the way parts are designed and manufactured with the ability to produce lightweight parts with unprecedented complex geometries which are o ...
Les ponts mixtes ont été largement utilisés en raison de leurs avantages économiques, constructifs et structuraux. Par ailleurs, le marché de la construction commence à tendre vers l’utilisation d’acier à haute résistance HSS. Ce genre d’acier séduit par s ...
Steel reinforcing bars in concrete are protected from corrosion by a thin oxide film that is created on the steel surface in the highly alkaline environment of the concrete. Corrosion process begins once this oxide film is destroyed, for example, by chlori ...
