TL;DR: In this article, solid particle erosion behavior of various polyaryletherketones (PAEKs) and their short-fiber reinforced composites has been characterised and the erosion rates (ERs) of these composites have been evaluated at different impingement angles and impact velocities.

TL;DR: In this paper, the effect of electric poling on the piezoelectric properties of sintered [xBZT-(1-x)BCT] ceramics is studied with varying poling temperatures and poling fields.
Abstract: Lead free piezoelectric ceramics barium zirconate titanate-barium calcium titanate, [xBZT-(1-x)BCT] (0.48≤ x ≤0.52), were synthesized by sol-gel method. Calcination of the as-synthesized precursor powders resulted in crystalline powders with single-phase perovskite structure at 700°C, which is significantly lower than that obtained by solid-state reaction. Solid-state sintering at 1450°C resulted in highly dense microstructure with ≥95% of the theoretical density. The effect of electric poling on the piezoelectric properties of the sintered [xBZT-(1-x)BCT] ceramics is studied with varying poling temperatures and poling fields. The results indicated that optimized poling conditions are required in enhancing the piezoelectric properties of [xBZT-(1-x)BCT] ceramics. The morphotropic phase boundary (MPB) composition, 0.5BZT-0.5BCT, showed a high remanent polarization (P r) of 12.2μC/cm2 and a low coercive field (E c) of ~0.14kV/mm. The optimized poling conditions resulted in high piezoelectric charge coefficient d 33 ~637pC/N, large electromechanical coupling coefficient k p ~59.6%, a large strain of 0.157%, a large piezoelectric voltage constant g 33 ~29mVm/N for (0.5BZT-0.5BCT) composition. In this report, the excellent piezoelectric properties of the sol-gel derived BZT-BCT ceramics has been analysed and correlated to its structure and poling conditions.

TL;DR: In this article, the authors developed a comprehensive theoretical model for erosion, valid for all impact angles, combining the concept of localization of plastic deformation leading to lip formation and the generalized energy absorption relations valid for both impact angles and all shapes of eroding particles.

TL;DR: In this article, an experimental investigation into the dynamic strain ageing (DSA) of a wrought Ni-base superalloy 720Li was conducted and the major characteristics of the serrations-i.e. critical plastic strain for onset of serrations, epsilon(c); (b) average stress decrement, Delta sigma(avg); and (c) strain increment between serrations.
