Abstract Scope |
The critical cooling rate for glass formation restrict their use in structural application. So, many researches tried to overcome the limitation of their dimensions by using powder metallurgy process such as Spark Plasma Sintering (SPS). In the present study, we will report the fabrication of Zr-based BMG by laser additive manufacturing (laser AM) and structural and mechanical difference between specimens which is fabricated by various process (as-cast, SPS and laser AM) through synchrotron X-ray scattering, TEM and nanoindentation mapping. Moreover, we can tailor microstructure and enhance properties of AM MG through rejuvenation. Finally, we suggest that we can design unique structure of bulk metallic glass through additive manufacturing and this unique structure also give us a chance to tailor properties further. |
