Abstract
Employing X-ray diffraction, scanning electron microscopy and differential scanning calorimetry techniques, the effect of the aluminium concentration on the glass forming ability (GFA) of Zr65Ni10Cu25–xAl x alloys were systematically studied. The experimental results show that with increasing Al concentration the supercooled liquid region of the as-quenched ribbons of Zr65Ni10Cu25–xAl x alloys increases and the critical cooling rate required to avoid crystallization during the rapid solidification for these alloys decreases, indicating that the GFA of Zr65Ni10Cu25–xAl x alloys is significantly improved by the addition of Al. The effect of Al on the GFA of Zr65Ni10Cu25–xAl x alloys is discussed from the micromechanism point of view.
