The fatigue behavior of I-phase containing as-cast Mg–Zn–Y–Zr alloy

The fatigue behavior of as-cast Mg–12%Zn–1.2%Y–0.4%Zr alloy has been investigated. The S–N curve showed that the fatigue strength at 107 cycles was 45 MPa. Scanning electron microscopy observations on the surfaces of the failed and unfailed specimens (after up to… Read moreThe fatigue behavior of I-phase containing as-cast Mg–Zn–Y–Zr alloy

The influence of mischmetal and tin on the microstructure and mechanical properties of Mg–6Zn–5Al-based alloys

The influence of the addition of mischmetal (MM) and tin (Sn) (total content of mischmetal and tin = 4 wt.%) on the microstructure, aging behavior and mechanical properties of Mg–6Zn–5Al-based alloys has been investigated. The microstructure of the as-cast alloys… Read moreThe influence of mischmetal and tin on the microstructure and mechanical properties of Mg–6Zn–5Al-based alloys

Transformation of ordered face-centered tetragonal ?-MnNi phase to face-centered cubic austenite during isothermal aging of an Fe–Mn–Ni alloy

The transformation of the grain boundary fct ?-MnNi precipitates to thermodynamically stable austenite was investigated in an Fe–Mn–Ni alloy using transmission electron microscopy (TEM). During aging of Fe–Mn–Ni alloys, fine bands began to develop in the ?-MnNi intermetallic particles. The… Read moreTransformation of ordered face-centered tetragonal ?-MnNi phase to face-centered cubic austenite during isothermal aging of an Fe–Mn–Ni alloy

Texture, microstructure and mechanical properties of equiaxed ultrafine-grained Zr fabricated by accumulative roll bonding

The texture, microstructure and mechanical behavior of bulk ultrafine-grained (ufg) Zr fabricated by accumulative roll bonding (ARB) is investigated by electron backscatter diffraction, transmission electron microscopy and mechanical testing. A reasonably homogeneous and equiaxed ufg structure, with a large fraction… Read moreTexture, microstructure and mechanical properties of equiaxed ultrafine-grained Zr fabricated by accumulative roll bonding

MFM analysis of the magnetization process in L10–A1 FePt patterned film fabricated by ion irradiation

Ga+ ions at a dose of 0.1 at.% (1.5 × 1014 ions cm?2) were irradiated by focused ion beam (FIB) onto L10 FePt films with a [0 0 1] crystalline texture normal to the film plane, and two-dimensional patterns composed… Read moreMFM analysis of the magnetization process in L10–A1 FePt patterned film fabricated by ion irradiation

Creep response and deformation processes in nanocluster-strengthened ferritic steels

There is increasing demand for oxide-dispersion-strengthened ferritic alloys that possess both high-temperature strength and irradiation resistance. Improvement of the high-temperature properties requires an understanding of the operative deformation mechanisms. In this study, the microstructures and creep properties of the oxide-dispersion-strengthened… Read moreCreep response and deformation processes in nanocluster-strengthened ferritic steels
