Thermal stability and mechanical properties of Gd-Co-Al bulk glass alloys
The glass forming ability of Gd-Co-Al ternary alloy systems with a composition ranging from 50％ to 70％ (molar fraction) for Gd and from 5％ to 40％ (molar fraction) for Al were investigated by copper mold casting and Gd60Co25Al15 bulk glass alloy cylinders with the maximum diameter of 5 mm were obtained.The reduced glass transformation temperature (Tg/Tm) and the distance of supercooling region Tx are 0.616 and 45 K,respectively for this Gd-Co-Al alloy.The compressive fracture strength (ヲf) and elastic modulus (E) of Gd-Co-Al glassy alloys are 1 1701 380 MPa and 5970 GPa,respectively.The Gd-Al-Co bulk glassy alloys with high glass forming ability and good mechanical properties are promising for the future development as a new type function materials.
