Plane stress yield loci are derived from an extensive bank of textural data which covers a range of fcc metals and alloys subjected to a wide range of thermomechanical processing operations. Results are given in terms of a parameter Y which describes the shape of the yield locus and corresponds to the ratio of the yield stress at balanced biaxial tension to the yield stress at pure shear. It is found that the yield loci indicative of good formability occur in metal sheets in which textural components are carefully balanced. For high stacking fault energy metals this corresponds to a mixture of cube texture with retained rolling texture components. For low stacking fault energy metals, the mixture is in the form of the brass annealing texture supplemented by components of grain growth texture. Improvements which can be gained in the formability with the latter texture are quite significant, while the former texture is capable only of restoring the formability to isotropic levels.

Combinatorial study of hydrogen storage alloys
Ölmez, Rabia; Öztürk, Tayfur; Department of Metallurgical and Materials Engineering (2009)
A combinatorial study was carried out for hydrogen storage alloys which involve processes similar to those normally used in their fabrication. The study utilized a single sample of combined elemental (or compound) powders which were milled and consolidated into a bulk form and subsequently deformed to heavy strains. Material library was obtained in a post annealing treatment carried out at elevated temperatures which brings about solid state reactions between the powders yielding equilibrium phases in the r...
Synthesis and characterization of zirconium based bulk amorphous alloys
Saltoğlu, İlkay; Akdeniz, Mahmut Vedat; Department of Metallurgical and Materials Engineering (2004)
In recent years, bulk amorphous alloys and nanocrystalline materials have been synthesized in a number of ferrous and non-ferrous based alloys systems, which have gained some applications due to their unique physico-chemical and mechanical properties. In the last decade, Zr-based alloys with a wide supercooled liquid region and excellent glass forming ability have been discovered. These systems have promising application fields due to their mechanical properties; high tensile strength, high fracture toughne...
COARSENING OF DELTA' (AL3LI) AND COMPOSITE PRECIPITATES IN AN AL-2.5-PERCENT LI-0.15-PERCENT ZR ALLOY
Aydınol, Mehmet Kadri (Springer Science and Business Media LLC, 1994-01-01)
The early stage coarsening behaviour of delta' (Al3Li) precipitates and composite precipitates, consisting of beta' (Al3Zr) core enveloped by a delta' shell, in an Al-2.5% Li-0.1 5% Zr alloy has been studied at 443, 473 and 503 K by conventional transmission electron microscopy using superlattice dark-field images. Coarsening kinetics of delta' precipitates was found to exhibit considerable deviation from the t1/3 law corresponding to diffusion control at 473 and 503 K. This deviation may be explained eithe...
Texture softening and strain instability in F.C.C. metals: Plane-strain deformation
Öztürk, Tayfur; Davies, Gwilym J. G (Elsevier BV, 1987-9)
An analysis was carried out into texture induced softening and the resulting strain instability in plane-strain deformation. A macroscopic model was employed in the analysis which viewed the deformation as the juxtaposition of suitably disposed positive and negative simple shears. With this model, the textural contribution to the rate of deformation hardening was computed in terms of a texture softening factor, S, this in a form that could readily be incorporated into the relevant conditions for strain inst...
Thickness effects in hydrogen sorption of magnesium/palladium thin films
Gharavi, Ayshe Gharemeshg; Öztürk, Tayfur; Department of Metallurgical and Materials Engineering (2012)
Magnesium (Mg) thin films with various thicknesses ranging from 50 to 1000 nm capped with nominally 20 nm Palladium (Pd) were prepared by a thermal evaporation unit. A total of 25 glass substrates were used in each experiment. The unit had a rotatable macro shutter, rectangular in shape, rotation axes opposite to the Mg source, which allowed controlled exposure of the substrates. Thin films of 50, 100, 150, 200, 300, 400, 500, 600, 800 nm and 1000 nm were produced in a single experiment. Hydrogenation and d...
