The present work deals with achieving improvement in the mechanical properties of SUS304L stainless steel through the application of a unique microstructure design termed as 'Harmonic structure', and establishing a co-relationship between various microstructural characteristics and mechanical properties. Harmonic structure essentially means a bimodal grain size distribution with a specific periodi

Aluminium-titanium (Al/Ti) composite sheets were fabricated via asymmetric accumulative roll bonding (AARB), which capitalises on additional shear to enhance plastic deformation. Multi-layers of Al alloy (AA1050) and commercially-pure Ti sheets were alternatively stacked and rolled-bonded with varied roll diameter ratios (dr) ranging from 1 to 2, for up to four passes. Annealing of selected compos

High-cyclic fatigue life in ultra-fine grained materials fabricated by equal channel angular pressing (ECAP) suffers from a specific shear texture induced during the fabrication as has been demonstrated in the present study on the example of pure copper. This texture promotes orientation of the easy glide crystallographic planes to be aligned parallel to the shear plane in ECAP. If specimens for t

Most of severe plastic deformation processes involve strain reversal. Till now quite big number of researches has been done on indirect study of its role, which discusses the effect of loading path in ultra-fine grained structure formation. This work is aimed to study directly the role of the strain reversal in grain refinement by severe plastic deformation. A 99.99% purity aluminum was processed

Twist extrusion (TE) is known as one of newly developed, but still moderately studied severe plastic deformation methods. This research was initiated to conduct a detailed study of structure-properties relationship evolution during TE processing. The evolution of macrostructure, Vickers hardness and tensile properties was studied in 99.99% purity aluminum during twist extrusion processing at room

Purpose of the Study: To identify policy gaps in the delivery and availability of assistive health technology (AHT) and medical devices (MD) for aging populations, particularly in low- and middle-income countries (LMICs). Design and Methods: The findings presented in this paper are the results of several narrative overviews. They provide a contextual analysis of the conclusions and evidence from W

School politics in Sweden has recently moved in a conservative direction, emphasising the importance of conventional school subjects, stronger teacher authority and more discipline in the classroom. At the same time, consensus on the utility of such measures is lacking in the school debate. The conservative approach is often criticised as misleading and behind the times in relation to contemporary
