Shear bands of as-cast and semi-solid Ti48Zr27Cu6Nb5Be14 bulk metallic glass matrix composites

Abstract

Bulk metallic glass matrix composites (BMGMCs) are similar to bulk metallic glass materials, and also have many advantages, including high elastic strain limit, high strength, good conductivity, and high magnetic permeability [1-3]. They have been widely used as semiconductors, superconductors, transformers, and other high magnetic permeability materials [4-6]. However, a fatal disadvantage of BMGMCs is poor plasticity, which can cause brittle fracture. This weakness has greatly limited their application in the field of engineering [7-9] .

Ball milling modification impact on the electromagnetic wave absorption properties of Fe83.3Si4B7P4Cu0.7Co1 amorphous powder

“…Their complex permeability is significantly affected by skin effect, favorable for the incidence of electromagnetic waves at high frequencies. These characteristics give them significant advantages in improving impedance matching, enhancing magnetic loss in the mid-high frequency range, and increasing dielectric loss, therefore garnering considerable interest in the domain of electromagnetic wave absorption [19][20][21][22][23] . Wu J L [11] et al successfully prepared amorphous alloy powders with a composition of Fe73.2Si16.2B6.6Nb3Cu1 using single roller strip casting and high-energy ball milling.…”
