چکیده انگلیسی
The effect of oxygen content on the glass forming ability of the Zr50Cu40Al10 alloy is presented. Two different oxygen levels, 194â¯Â±â¯26â¯wt. ppm and 918â¯Â±â¯72â¯wt. ppm, in the arc melted and suction cast alloys were obtained using Zr metal of different forms and nominal oxygen contents. Critical diameters for glass formation were determined by microstructural observations of cast conical and rod-shaped samples. Their structures were further investigated by X-ray diffraction. The critical diameter of the alloy with the lower oxygen content was 8â¯mm, while for the higher oxygen content it was below 3â¯mm. For the latter, the Ï3 (Zr51Cu28Al21) crystalline inclusions were observed in the central part of the 3â¯mm diameter sample. The fully amorphous samples exhibited a large supercooled liquid range and a high reduced glass transition temperature.
