... and ductile. To reflect the ductile behavior in ceramics, promoted by the HPPT, a pressure sensitive Drucker–Prager constitutive model is used [ 16 ]. To accommodate the thermal softening behavior, a thermal softening curve (Fig. 2 ) is incorporated in the model. This yield strength curve is obtained...

... tests carried out on specimens cut from different positions in the tubes parallel to their axes. The distributions of the Vickers hardness over the surfaces at 0 deg and 90 deg to the drawing direction were examined. It was found that the microhardness, yield strength, and ultimate tensile...

... backscatter diffraction. From these measurements, the geometrically necessary dislocation (GND) density that the material contains has been estimated. The yield strength increment was then calculated from the GND distribution by using the Taylor model and integrated into each material point of the finite...

... on the residual stress resulting from AWJP was studied. Treatments were conducted on steel, as well as nickel and titanium alloy targets subjected to an elastic prestress ranging from 0% to 75% of the material’s yield strength. The results showed that a tensile elastic prestress increases the surface residual...

... to pure magnesium, the mechanical properties including tensile strength and yield strength of the Mg ∕ Si C nanocomposites were improved significantly, while the good ductility of pure Mg was retained. The grain size of the pure magnesium was refined significantly when SiC nanoparticles were dispersed...

... with increased hardness and yield strength will be developed in the near future that significantly improves the durability for tools manufactured with diameters in the tens to hundreds of microns. To enable a significant increase in performance and productivity requires higher spindle speeds and increased...
