Improved Thermal Stability of Amorphous ZrAlCuNi Alloys with Si and B
Both the glass forming ability and thermal stability of the Zr<SUB>65-x-y</SUB>Al<SUB>7.5</SUB>Cu<SUB>17.5</SUB>Ni<SUB>10</SUB> amorphous alloy can be improved by the appropriate addition of Si and B. The metalloid elements would extend the nucleation stage and result in more small crystalline particles. The basic crystallization kinetics for the Si/B containing alloys is still similar to the base alloy, but would proceed at a higher temperature or a more sluggish speed.
