Sensitivity study of crack driving force predictions in heterogeneous welds using Vickers hardness maps [PDF]
, 2016 Weld flaws often require an engineering critical assessment (ECA) to judge on the necessity for weld repair. ECA is a fracture mechanics based prediction of the integrity of welds under operating conditions.

The effect of quenching and defects size on the HCF behaviour of Boron steel [PDF]
, 2014 This work investigates the effect of natural and artificial surface defects and quenching on the fatigue strength of a Boron steel (22MnB5). A vast experimental campaign has been undertaken to study the high cycle fatigue behaviour and more specifically ...

The Anatomical Record, EarlyView.Abstract Bats possess the remarkable ability to fly, and with this, distinctive wing bone properties. We investigated the structural, mechanical, and compositional properties of the humerus, radius, metacarpals, and proximal and middle phalanges of Carollia perspicillata, an approximately 15 g fruit‐eating bat native to the Neotropics.

Hardening mechanism of commercially pure Mg processed by high pressure torsion at room temperature
, 2014 Coarse-grained Mg in the as-cast condition and fine-grained Mg in the extruded condition were processed by high pressure torsion (HPT) at room temperature for up to 16 turns. Microstructure observation and texture analysis indicate that to fulfil the Von

Micro-Vickers Hardness of Intermetallic Compounds in the Zn-rich Portion of Zn–Fe Binary System
ISIJ International, 2018 are frequently observed on the α Fe/ Γ phase boundary or in the Γ phase layer. 1,7) Therefore, mechanical properties of the IMCs (especially, Γ phase) are a key issue to be examined for improving the formability of Annealing temperature and composition ...

‘These reforms have teeth’: The affective dimensions of teacher education policy enactment
British Educational Research Journal, EarlyView.Abstract The affective dimensions of education policy enactment have often received less attention in the research literature, especially regarding teacher education policy. This article reports on a study of the affective responses of university‐based teacher educators in England to the significant initial teacher education reforms of 2019–2022: the ...

Vickers Hardness of Diamond and cBN Single Crystals: AFM Approach
, 2017 Atomic force microscopy in different operation modes (topography, derivative topography, and phase contrast) was used to obtain 3D images of Vickers indents on the surface of diamond and cBN single crystals with high spatial resolution.
