Specific volume study of a bulk metallic glass far below its calorimetrically determined glass transition temperature
Abstract
<p>High-precision LASER dilatometry with a unique measurement setup was applied to the bulk metallic glass alloy Zr52.5Ti5Cu17.9Ni14.6Al10 (Vit105) for specific volume studies. Employing small temperature steps of Î"T=5 and 10 K and long measurement times effective heating rates of the order of 10â2 K/min were realized and changes of the specific volume were measured with a resolution of Î"V/V=10â6 down to 573 K. The temperature regime of these experiments is far below a calorimetrically determined glass transition of Tgcalor=659 K (5 K/min). The experimental results strongly support theoretical predictions for the existence of an ideal glass transition that was observed in this study at Tg=628 K for this bulk metallic glass model alloy.</p>
