Welding the Inconel 718 Superalloy: Reduction of Micro-segregation and Laves Phases

Explores the day-to-day welding business in Alloy 718 and presents solutions to avoid or minimize micro-segregation. It considers the limitations of changing from lab scale models to actual production models and presents new technologies with proven experimental background. Various case studies are presented within the text, as well as proposed solutions backed by experimental evidence. Items previewed in this edition include enhanced cooling rates in the GTA welding process with cryogenic cooling and enhanced dendrite refinement using modified pulse waveform.

This work will be useful to researchers from the aerospace, space, power generation, nuclear, and chemical industries, as well as students interested in superalloys and welding.
