BULK SOLIDIFYING AMORPHOUS ALLOYS WITH IMPROVED MECHANICAL PROPERTIES

摘要

Bulk solidifying amorphous alloys exhibiting improved processing and mechanical properties and methods of forming these alloys are provided. The bulk solidifying amorphous alloys are composed to have high Poisson's ratio values. Exemplary Pt-based bulk solidifying amorphous alloys having such high Poisson's ratio values are also described. The Pt-based alloys are based on Pt-Ni-Co-Cu-P alloys, and the mechanical properties of one exemplary alloy having a composition of substantially Pt<SUB>57.5</SUB>Cu<SUB>14.7</SUB>Ni<SUB>5.3</SUB>P<SUB>22.5</SUB>are also described.
