Phase stability, porosity distribution and microstructural evolution of amorphous Al50Ti50 powders consolidated by electrical resistance sintering

The effect of intensity and duration of the electrical resistance sintering process on the phase stability, porosity distribution and microstructural evolution of Al50Ti50 amorphous powders is studied. The phase transformations during the consolidation process were determined by X-ray diffraction. T...
