Title:
MANUFACTURE OF HIGH TOUGHNESS AND HIGH STRENGTH AMORPHOUS ALLOY MATERIAL
Document Type and Number:
Japanese Patent JP3302031
Kind Code:
B2
Abstract:
PURPOSE: To manufacture the high toughness and high strength amorphous alloy material by heating an amorphous phase alloy in such a manner that intermetallic compounds are not produced and dispersing crystalline grains in which the elements to be added are allowed to supersaturatingly enter into solid solution under specified conditions.
CONSTITUTION: For example, an Al base amorphous alloy having a compsn. essentially consisting of Al and contg. rare earth elements and other elements (Ni, Fe, Co and Cu) is heated to a temp. at which intermetallic compounds or other compounds are not formed. In this way, crystalline grains consisting of uniformly dispersed main elements (face-centered cubic crystals) having 5 to 500mm diameter and 5 to 50% volume rate and the elements to be added are precipitated into the amorphous matrix to obtain the amorphous alloy material excellent in mechanical strength and toughness.
