Abstract

Ductile Al-Y-Ni and Al-Ce-Ni amorphous alloys were found to exhibit a glass transition at temperatures just below crystallization temperature. The glass transition temperature increases from 490 to 582 K with increasing solute concentration. The difference in specific heat between amorphous solid (AS) and supercooled liquid (SL) reaches 9.2 J/mol-K and the temperature coefficient of expansion and viscosity of the supercooled liquid are 100×10-5 K-1 and 3×1013 poise. By the transition of AS to SL, the Young's modulus and tensile strength also decrease steeply by about 63 and 66%, accompanied with an increase of elongation by about 320%.
