Ingots of an oxide dispersion strengthened reduced activation ferritic steel with the Fe-14Cr-2W-0.3Ti-0.3Y(2)O(3) chemical composition (in wt.%) were synthesized by mechanical alloying of elemental powders with 0.3 wt.% Y2O3 particles in a planetary ball ...
Reliable collapse assessment of structural systems under earthquake loading requires analytical models that are able to capture component deterioration in strength and stiffness. For calibration and validation of these models, a large set of experimental d ...
This thesis is an exploration of deformation and fracture properties of a novel two-phase α2 + γ Ti46Al8Ta (at.%) alloy featuring a "convoluted" microstructure, produced by partners within a European Union project named IMPRESS. Properties of this alloy ar ...
Copper and copper alloys typically experience a sharp loss in ductility at intermediate temperature, induced by grain boundary damage and fracture processes. The susceptibility of the material to intermediate temperature embrittlement is, as a result, stro ...
As the upper temperature for use of reduced activation ferritic/martensitic steels is presently limited by a drop in mechanical strength at about 550 degrees C, Europe, Japan and the US are actively researching steels with high strength at higher operating ...
In this work we have studied brittle fracture in high-chromium reduced activation tempered martensitic steels foreseen as structural materials for thermonuclear fusion reactors. Developing the adequate materials that can withstand the severe irradiation co ...
The 2008-2009 work programme of the European research project on nano-structured oxide dispersion strengthened (ODS) reduced activation ferritic (RAF) steels is being organized along the four following programmatic lines: (1) improve the present generation ...
Face-centered cubic (fcc) to body-centered cubic (bcc) martensitic transformations occur in many materials, such as steels, FeNi meteorites or brass. The phenomenological theory has been the accepted theory for these transformations for more than half a ce ...
This book presents a refined methodology to predict fatigue life of high-strength steels: Uniform Material Law (UML) for High-Strength Steels. In contrast to other available methods, UML is a handy method as only tensile strength data of metals are needed ...
The goal of this project was to develop low-firing thick-film materials systems for the fabrication of piezoresistive sensors on special steels, for the fabrication of instrumented medical devices. To this end, a series of individual thick-film materials a ...
