Strengthening of a Biodegradable Mg–Zn–Ca Alloy ZX50 After Processing by HPT and Heat Treatment
This study investigates a biodegradable Mg–5Zn–0.3Ca alloy (ZX50) during HPT-processing and long-term heat treatments, the latter with respect to the evolution of intermetallic precipitates and vacancy cluster...

Open AccessEvolution of strength and structure during SPD processing of Ti–45Nb alloys: experiments and simulations
A β-phase Ti–45Nb alloy was processed by several severe plastic deformation (SPD) methods as high-pressure torsion, cold rolling and folding, and hydrostatic extrusion to enhance its strength by achieving an u...

Open AccessEnhancement of mechanical properties of biocompatible Ti–45Nb alloy by hydrostatic extrusion
β-Type titanium alloys are promising materials for orthopaedic implants due to their relatively low Young’s modulus and excellent biocompatibility. However, their strength is lower than those of α- or α + β-ty...

High-Pressure Torsion to Improve Thermoelectric Efficiency of Clathrates?
High-pressure torsion (HPT), as a technique to produce severe plastic deformation, has been proven effective to improve the thermoelectric performance of skutterudites. In this report, we present microstructur...

Dependence of the Elastic Moduli of Skutterudites on Density and Temperature
The dependency of Young’s and shear modulus on relative density and temperature was determined for three series of skutterudites: p-type MmyFe3CoSb12 (y = 0.70, 0.80), p-type DDyFe3CoSb12 (y = 0.65, 0.68) and n-t...

Fragmentation in Large Strain Cold Rolled Aluminium as Observed by Synchrotron X-Ray Bragg Peak Profile Analysis (SXPA), Electron Back Scatter Patterning (EBSP) and Transmission Electron Microscopy (TEM)
In the last decade investigations of plastic deformation have focussed on the large strain ranges, i.e. stage IV and V of deformation [1–5]. Although several models have been developed to explain the work hardeni...

Analysis of isothermal and isochronal annealing in deformed Zn and Zn-Ag
Zn and Zn-Ag polycrystals have been deformed by rolling at 293 K to true strains ε=0.05–3.8. After deformation, samples were subjected to isothermal and isochronal anneals, and thereby investigated by intermit...
