Shear Banding in Metallic Glasses: Major Weakness or Potential Advantage?

Metallic glasses (MGs) look like metals and have the intimate structure and sometimes the behavior of glasses. The first reported scientifically obtained MG was the alloy Au75Si25 produced at Caltech by Klement et al., in 1959, by extremely rapid cooling of the Au-based melted alloy. Due to the high solidification rate required to produce MGs, the section thickness was small, i.e. only a few tens of micrometers, typically 20 to 50m [5-7].

Effect of C and Ce addition on the microstructure and magnetic property of the mechanically alloyed FeSiBAlNi high entropy alloys

Highlights FeSiBAlNi (C, Ce) amorphous HEAs have been fabricated by mechanical alloying. The effects of C and Ce addition were investigated. Ce addition exhibits a remarkably enhanced effect on glass forming ability (GFA). C and Ce additions are beneficial to enhance thermal stability.

Formation of highly thermal stable Al88Ni6Y6 amorphous composite by graphene addition design

We study the effect of graphene (Gr) addition on the amorphisation and thermal stability of the Al88Ni6Y6 + x wt.% Gr (x = 0, 0.2, 0.5, and 0.8) alloys during mechanical alloying. The final milling-products consist of the amorphous phase and a few nanocrystals with face-centered cubic (fcc)structure, and the AlNiY(Gr) amorphous composites have been fabricated. We find that the 0.2 wt.% Gr addition obviously benefits the amorphisation and remarkably

Evaluation of flow units and free volumes in metallic glasses

We investigate the changes of the fractions of flow units and free volumes in two typical metallic glasses by variation of their preparation cooling rates. It is found that the fractions of the flow units and the free volumes show a similar dependence on the cooling rate, which is suggestive of the existence of a strong connection between them. The microstructural correlation between flow units and free volumes of the metallic glasses is discussed,

Correlation between glass transition temperature and melting temperature in metallic glasses

We report that the glass transition temperature (Tg) of a variety of metallic glasses (MGs) correlates with the eutectic or peritectic temperature of two main components corresponding stoichiometric proportion in their binary phase diagram. The correlation suggests that the Tg of MGs is mainly determined by their solvent of two base components, which have composition close to the eutectic and peritectic points in the binary phase diagram and the

A critical study of the emergence of glass and glassy metals as “green” materials

The work reported in this paper discusses the importance of glass and metallic glasses as environmen- tal friendly materials and also provide some points of view about the future influenceof these materials for the related fieldsof industrial engineering and industrial ecology.The environmental capabilities of metallic glasses (MGs),which are consider ed to be among the impo rtant materials of the future,have not been sufficientlyinvestigated.However,some

Researches on the failure modes under tensile forces of the Resistance Spot Welding (RSW) joints

Resistance spot welding (RSW) is one of the most used methods of joining sheet metals. The RSW process is based on Joule Lenz effect, of the electric current passing trough the (similar or dissimilar ) joining metal sheets positioned between the two contact electrodes. At welding process , some important changes occurs in metallurgical and mechanical properties of the welded areas and heat affected zones (HAZ) . The purpose of this work is to highlight
