Highlights

Metallic glasses are a fascinating class of metallic materials that do not display long-range atomic order
Metallic glasses become relatively malleable when heated in the supercooled liquid region, allowing moulding and shaping with microscale precision by means of thermoplastic processing [7]
Novel routes to enhance plasticity of metallic glasses include procedures to hinder shear band propagation. This can be achieved, for example, by designing composite materials consisting of particles which act as second-phase reinforcements embedded in the amorphous matrix [9,10]

Summary

Introduction

Metallic glasses are a fascinating class of metallic materials that do not display long-range atomic order. Some metallic glasses have been found to exhibit superior soft magnetic properties [3], good magnetocaloric effects [4] and outstanding catalytic performance [5], having potential for a widespread range of technological applications [6]. This low plastic deformation, evidenced when testing metallic glasses under tension, is related to the formation and rapid propagation of shear bands [2].
