Abstract
The mechanical properties (i.e., tensile fracture strength and Young’s modulus) of eight different alloys of a new class of metallic glasses containing up to 90 at. % aluminum are reported along with crystallization temperatures of these alloys. The Al90Fe5Ce5 material has a tensile fracture strength of 940 MPa (1 MPa=145 psi), while two others (Al87Fe8.7Gd4.3 and Al87Ni8.7Y4.3) exceed 800 MPa. Young’s modulus measurements for three of these exceed 60 GPa with a high value of 66 GPa for the Al90Fe5Ce5 glass. These unusually high strengths of the aluminum glasses can be of significant importance in obtaining high‐strength, low‐density materials.This publication has 2 references indexed in Scilit:
