Recent observations indicate that very high deformation temperatures (673 K corresponding to 0.7 of Mg's melting point) by high pressure torsion (HPT) are mandatory to successfully synthesize bulk Mg-Fe nanocomposites with homogenous microstructure a

Abstract Widespread application of magnesium (Mg) has been prevented by its low strength and poor corrosion resistance. Core of this limitation is Mg’s low electrochemical potential and low solubility for most elements, favoring secondary phase pre

Severe plastic deformation (SPD) is effective in producing bulk ultrafine-grained and nanostructured materials with large densities of lattice defects. This field, also known as NanoSPD, experienced a significant progress within the past two decades.

Increasing the yield stress of twinning-induced plasticity (TWIP) steels is a demanding task for modern materials science. This aim can be achieved by microstructure refinement induced by heavy straining. We feature the microstructural evolution and

The correlations between process conditions, microstructure, and mechanical properties of additively manufactured components are not fully understood yet. In this contribution, three different hatch strategies are used to fabricate rod-like samples f

The effect of high-pressure torsion (HPT) on the corrosion behavior of extruded ZX00 (Mg-0.45wt%Zn-0.45wt%Ca) in phosphate buffered saline solution is investigated. MgCaZn alloys are promising candidates for the use as bioresorbable implant materials
