  • Description:
    The Bureau of Mines is studying the influence of capacitor discharge welding (CDW) on alloy microstructures and assessing the effects of welding parameters on fusion and heat affected zone formation. Mechanically alloyed (MA} aluminum affords unique opportunities to study the effect of this low heat input process on nonequilibrium microstructures. In this study, samples of IN-9021 and MA AlTi have been CDW to form similar metal joints. In addition, dissimilar metal welds have been formed by CDW of MA AITi to commercially pure Ti and Ti-6Al-4V. The strengths of the resulting joints have been determined from tensile tests of the welded samples. Microhardness measurements have also been used to assess the quality of the joint. Optical, scanning and transmission electron microscopy have been used to study the failure characteristics of the weld and changes in the microstructure due to the welding process.
