| Abstract Scope |
Direct laser deposition (DLD) presents unique opportunities and challenges for the fabrication of metallic glass components. The small melt volume and rapid quenching inherent to DLD processing tends to favor glass formation from the liquid, while cyclic reheating during deposition of subsequent tracks and layers can result in relaxation of the glass and ultimately crystallization. Here, we present a study of DLD-processed Cu-Zr alloys, examining the role of composition and processing conditions on the resulting atomic- and microstructure and local mechanical properties. Earlier work demonstrated that DLD provides an efficient means to identify the glass forming composition range in Cu-Zr and other alloy systems and identify the composition with the highest glass forming ability. In the present work we apply nanoindentation and advanced microscopy methods to examine local variations in glass structure and properties as a function of position within the DLD melt zone, heat affected zone, and surrounding build. |
