Shear Band Formation in Bulk Metallic Glasses

In recent times, there has been a growing interest in the machining of amorphous metallic alloys, which are also called bulk metallic glasses (BMGs). These materials differ from common polycrystalline metallic alloys, because their atoms do not assemble on a crystalline lattice, and as a result, they have unique physical, mechanical, and chemical properties. A number of BMGs have been found to ...

SPIN-GLASSES IN AMORPHOUS (Ni100-x Fex) 79P1 3B8 ALLOYS

Dilute amorphous (Niioo-xe )79138 alloys exhibit usual characteristics of spin glasses : freezing temperatures T (sharp cusp in zero-field susceptibility) proportional to x up to x=4 at. %. However, the magnetization does not follow the Blandin-Souletie-Tournier scaling laws. Such an anomaly can be explained within a model of ferromagnetic clusters coupled bt RKKY interaction. INTRODUCTION.From...

Deformation in Metallic Glasses Studied by Synchrotron X-Ray Diffraction

High mechanical strength is one of the superior properties of metallic glasses which render them promising as a structural material. However, understanding the process of mechanical deformation in strongly disordered matter, such as metallic glass, is exceedingly difficult because even an effort to describe the structure qualitatively is hampered by the absence of crystalline periodicity. In sp...

Formation of Ti-Zr-Cu-Ni bulk metallic glasses

Formation of bulk metallic glass in quaternary Ti-Zr-Cu-Ni alloys by relatively slow cooling from the melt is reported. Thick strips of metallic glass were obtained by the method of metal mold casting. The glass forming ability of the quaternary alloys exceeds that of binary or ternary alloys containing the same elements due to the complexity of the system. The best glass forming alloys such as...
