Microstructural Observations of Fusion Welded Boron-Aluminum Composites

Abstract

Welding studies were conducted on boron-aluminum (B/Al) composites to observe the effects of gas-tungsten arc fusion welding on the boron reinforcing filaments and aluminum matrix. The objective of this investigation was to determine the basic potential of fusion welding B/Al composites for possible structural applications. Microstructural observations after welding revealed matrix fusion without apparent boron filament damage. Analysis of weld metal regions indicated that aluminum filler metal additions intermixed with the matrix and altered its chemical composition. It is concluded that fusion welding of B/Al composites may be possible by control of welding energy input.
