Effect of testing conditions on the nanomechanical behavior of surface and inner core of as-cast Zr-base bulk metallic glassy plates
2022, Materials Science and Engineering: ACitation Excerpt :In case of synthesis of ribbons using melt spinning, a directional process involves strong shearing of the liquid during quenching into the glassy phase [17]. The X-ray and neutron scattering studies have revealed that the structure function S(Q) has varied along different directions of the ribbons [18,19]. The tensile yield stress has been estimated to be higher by a few percentages along the ribbon length than that along the width direction [20].
Flow-induced elastic anisotropy of metallic glasses
2016, Acta MaterialiaCitation Excerpt :Small-angle neutron scattering suggests aligned defects possibly connected with the shearing [4,5]. Both X-ray and neutron scattering show that the structure function S(Q) is different in different directions in ribbons [6,7]. The yield stress has been measured in tension parallel to the ribbon length and parallel to the width; it is consistently higher parallel to the length, typically by a few percent but possibly by much more [8,9].
Field annealed closed-path fluxgate sensors made of metallic-glass ribbons
2012, Sensors and Actuators, A: PhysicalCitation Excerpt :It appears that the bending stress σ slightly lowers the HRA anisotropy in the as-cast as well as in the annealed state – the loops of #2 TORs are less slant and/or display a steep low-field part (Fig. 2b). The reason of the poorly reproducible as-cast HRA anisotropy could be the as-cast structural anisotropy [15] or a creep anisotropy induced by intrinsic macroscopic stress acting in the still hot “fresh” ribbon at the end of casting. Similar resulting anisotropy is observed after no-intentional-stress annealing in some Fe–Nb–Cu–B–Si ribbons with the same sign of creep-induced anisotropy [16].
