A fiber laser beam is used to butt-weld of identical Ti43·3Zr21·7Ni7·5Be27.5 (at.%) bulk metallic glass (BMG) specimens. Various tests, such as SEM, TEM, XRD, DSC, and Vickers hardness, are conducted on the welded specimens to analyze the crystall

In this study, the deoxidation behavior of Zr powder with the use of a Mg reductant is discussed. The original Zr powder was produced by the hydride-dehydride (HDH) method. The raw Zr powder has a thick surface oxide layer of 43 nm as well as high ox

Bulk metallic glass (BMG) alloys have been known to show superior formability under a Newtonian viscous mode in a supercooled liquid region (SLR). Crystalline phases generated by a high-temperature forming process have a negative effect on the formab

Equal channel angular pressing (ECAP) is the most promising and interesting process for refining the grain size to an ultrafine grain or nanosize by imposing severe plastic deformation into the workpiece and repeating the process while maintaining th

A constitutive equation based on a free volume model, that describes the strain rate dependent deformation behavior of bulk metallic glasses (BMGs) within the supercooled liquid region, has been modified in this paper in order to reproduce the stress
