| Abstract: | An investigation of gas tungsten arc welding technique was carried out to improve the microstructure and properties of weld joint of FeAl alloy sheet. The studies show that the tensile strengh of weld joint is as high as 80 percent of that of FeAl alloy sheet by using thin FeAl alloy bar and 1Cr18Ni9Ti rod as welded alloy and selecting suitable welding parameters. Treeings are distributed over the most areas of weld region and some equal axle crystals are in the center. Recovery and recrystallization structure are gained in the heat affected zone. |
