Abstract
The objective of this work was to determine if a processing window could be found for the friction stir welding of the bulk metallic glass Vitreloy 106A that preserved the material's amorphous nature. In this investigation a sample of Vitreloy 106A was friction stir welded with selected processing parameters including preheating to 662°F (350°C). X-ray diffraction and differential scanning calorimeter were used to determine the extent of devitrification induced into the metal. The extent of devitrification was plotted as a function of processing parameters and observed that the extent of devitrification decreased with the increase in the average specific heat, pseudo heat index 1 (RPM/1PM* Plunge Force) and pseudo heat index 11 (RPM/IPM * Forge Force). This paper describes the effect of processing parameters on the friction stir welded bulk metallic glass.
