On the effect of Ti on Oxidation Behaviour of a Polycrystalline Nickel-based Superalloy [PDF]

, 2018
Titanium is commonly added to nickel superalloys but has a well-documented detrimental effect on oxidation resistance. The present work constitutes the first atomistic-scale quantitative measurements of grain boundary and bulk compositions in the oxide ...

Insight of the dendrite's deformation and fracture in large-sized single-crystal superalloy blades for the formation of slivers

Journal of Materials Research and Technology
The manufacturing of single-crystal superalloy blades consistently aims to avoid grain boundary defects that compromise crystal integrity. Although slivers represent a significant type of grain boundary defect, their formation mechanisms remain ...
