Carbides constitute a class of materials used for many applications, where excellent mechanical properties, such as stiffness, hardness and fracture toughness, are required. The machining industry is a typical example where carbide are crucial materials. W ...
Here, we discuss a novel, mixed mode 3D XYZ scanner built within a single foundry process. The device has a large range of motion in X, Y, and Z (14.1 mu m in X and Y and 97.9 mu m in Z) and can also rotate about two axes (7.4 degrees), making it a 5 degre ...
High throughput first-principles calculations were employed to unravel the thermodynamic stability of two sets of hierarchical phases, β′′′P and β′′′S, in Mg-RE (rare-earth) alloys. The β′′′P orderings (with compositions greater than xRE=0.125) are predict ...
During casting, thermally induced deformations give birth to ingot distortions and residual stresses. For some high strength alloys, ingot cracking can happen during casting per se or during cooling down. Ingot distortions such as rolling face pull-in, but ...
Le moteur Lavet est très utilisé dans les montres électroniques. Le but étant toujours de minimiser la taille de ce moteur sans compromettre ses performances, il doit être optimisé lors de son dimensionnement. Du point de vue du champ magnétique, ce moteur ...
During solidification of metallic alloys, coalescence corresponds to the formation of solid bridges between grains when both solid and liquid phases are percolated. As such, it represents a key transition with respect to the mechanical behaviour of solidif ...
We investigate processing-microstructure relationships in the production of Al2O3 particle reinforced copper composites by solidification processing. We show that during production of the composites by gas-pressure infiltration of packed Al2O3 particle pre ...
The majority of muscles, nerves, and tendons are composed of fiber-like fascicle morphology. Each fascicle has a) elongated cells highly aligned with the length of the construct, b) a high volumetric cell density, and c) a high length-to-width ratio with a ...
During solidification of metallic alloys, coalescence leads to the formation of solid bridges between grains or grain clusters when both solid and liquid phases are percolated. As such, it represents a key transition with respect to the mechanical behavior ...
The rigidity temperature of a solidifying alloy is the temperature at which the solid plus liquid phases are sufficiently coalesced to transmit long range tensile strains and stresses. It determines the point at which thermally induced deformations start t ...
