- •
The behaviour of γ′ phase to thermal and mechanical effects during rapid heating of Astrology
- •
The thermo-mechanical affected zone (TMAZ) and heat affected zone (HAZ).
- •
significantly enhanced resistance to weld liquation cracking of the alloy.
- •
This was not observed in purely thermally simulated samples.
- •
The microstructure within the TMAZ of the as-welded alloy is similar to the microstructure in the forged Gleeble specimens.
