Special Issue Information

Dear Colleagues,

Metallic glasses (often referred to as glassy alloys or amorphous alloys) were first widely studied in the 1960s, because they possess both desirable properties of conventional crystalline metals and the formability of conventional oxide glasses. The successful synthesis of various bulk metallic glasses in the late 1980s, permitting minimum section thickness over 1 cm or even larger, has stimulated great enthusiasm in the study of this class of novel metallic materials. Since the beginning of the 1990s, substantial progress has been made in the understanding of physical, chemical and mechanical properties of metallic glasses. Then, over the past 20 years there have been a number of attempts to commercialize bulk metallic glasses. Metallic glasses are still a subject of intensive research in the international metals community. From an application perspective, it is clear that metallic glasses have an interesting combination of properties such as very high strength, very high hardness, large elastic elongation limit, potential for high fracture toughness, and superior corrosion resistance. However, to obtain viable industrial applications we need an alloy is harder and stronger than and is at least as tough as stainless steels, with similar costs. The alloy also needs to have superior corrosion resistance and is high processability. Although we understand metallic glasses much better today, there are still significant gaps in our knowledge that hinder widespread uses of metallic glasses. The goal of this Special Issue is to discuss major materials issues for metallic glasses, from tailor-made design to process optimization, from structures to properties, and from the fundamental science to viable industrial applications. In this Special Issue, we hope to deepen understanding of why metallic glasses attract such intensive interest, as well as highlight some challenging issues awaiting resolution to provide viable paths to more active applications of metallic glasses.

The different deformation behaviors in the yield stage, in particular, of metallic glasses under uniaxial tension and compression are investigated from an atomic structural perspective, by applying both experimental and simulation methods. A new computational approach for quantitatively calculating free volumes (FVs) in structural models is developed, based on which the manner in which FVs contribute to deformation is studied. It is found that FVs have different expansion behaviors in terms of their saturation sizes and corresponding strain values, which are essential structural causes of different yield behaviors in these two deformations in metallic glasses.
