Abstract
The addition of glass formers, B and P, raises not only the shear stiffness but also the tensile yield strain (εy) of Fe‐ and Co‐based glasses. εy increases by a factor of 2 from 1.23×10−2 for Pt–Ni–P glasses to 2.45×10−2 for Fe–B glasses as the Poisson’s ratio decreases from 0.42 to 0.32. The Vickers hardness of a Fe75B25 glass attains 1300 kg/mm2 which is the highest value reported for metallic glasses. The directionality of interatomic forces either due to atomic ordering or s‐d hybrid bonding in transition metals is proposed to be responsible for this behavior.This publication has 9 references indexed in Scilit:
