Aluminum zinc alloys constitute an important class of wrought alloys, the so-called 7000 series, and are also widely used as anti-corrosion coatings of steel sheets. They are also interesting from a more fundamental point of view because zinc, a hexagonal ...
Growth directions and crystallographic orientations of solidification microstructures have been measured in Al-Zn alloy near the eutectic composition. Al dendrites in Al-92 wt.% Zn alloy were found to grow along the I 10) directions while Zn dendrites in A ...
In a recent contribution, we have reported that dendrites in the aluminum-zinc binary system can change their growth direction continuously from {100} to {110} as the concentration of zinc CZn increases from 5 to 90 wt pct.[1] This was interpreted as an in ...
Numerical modelling of fatigue behavior for anisotropic structures has become critical for design applications. This is particularly true for forged components due to the intrinsic anisotropy of the material resulting from the process. The aim of this stud ...
The origin of intragranular variations of the crystallographic orientation in hot-dip Al-Zn-Si coatings is discussed based on new experimental results and modelling. The solidification microstructure in as-received 55Al-43.4Zn-l.6Si (in wt.%) coatings depo ...
A heterogeneous charge transport model for microcrystalline silicon based on fluctuation-induced tunneling is presented that fits the low-temperature saturation observed in dark conductivity measurements and accounts for the film microstructure. Excellent ...
Standard theta-2 theta and pole figure X-ray diffraction techniques were used to study structural properties and preferred orientation of nanostructured TiAIN thin films prepared using cathodic are deposition. Systematic collection of reflections from latt ...
Pressure-induced successive phase transitions of micro-, submicro-, and nanocrystalline NaNbO3 particles were investigated by high-pressure Raman spectroscopy. Microcrystalline NaNbO3, which stabilizes in an orthorhombic Pbcm structure at ambient pressure, ...
W-(0.3-2)Y2O3 and W-(0.3-2)Y materials (in wt.%) have been manufactured by conventional powder metallurgy methods including dry mechanical alloying of elemental powders in Ar atmosphere, cold pressing in air using a pressure in the range of 150-250 MPa and ...
The transformation of pyroxene to its high-pressure polymorph akimotoite (MgSiO3 ilmenite type structure) is documented in the shock-induced melt veins of the L6 Tenham chondrite. Four textural relationships between pyroxene and akimotoite are observed in ...
