Abstract:

NUCu-140 and 10 wt Ni steel were developed as candidate materials for use in naval and structural applications. However, prior to this research project, a fundamental understanding of the phase transformation behavior under the high heating and cooling rates associated with welding thermal cycles was not available for these alloys. For NUCu-140, the potential use of multiple thermal cycles was investigated with HAZ simulations using a Gleeble thermo-mechanical simulator. For 10 wt Ni steel, the effect of rapid heating and cooling rates associated with welding thermal cycles was established for the first time.
