Effect of forging pressure on the microstructure of linear friction welded Inconel 738 superalloy

Show other versions (1)

Inconel 738, which is a nickel base superalloy used for hot section components of aircraft and industrial turbines is difficult to fabricate and repair by fusion welding due to its susceptibility to heat affected zone (HAZ) intergranular cracking. Crack-free joining of the difficult-to-weld alloy is...
