Microstructure investigations of Pt-modified γ′-Ni3Al + γ-Ni coatings on Ni-based superalloys

Interdiffusion Behavior of Pt-Diffused γ+γ' Coatings on Ni-Based Superalloys

Platinum-diffused γ+γ' coatings (~20 at.% Al, ~22 at.% Pt) were synthesized on René 142 and René N5 Ni-based superalloys by electroplating the substrates with ~7 μm of Pt, followed by an annealing treatment in vacuum at 1175°C. In order to study the compositional and microstructural evolution of these coatings at elevated temperatures, interdiffusion experiments were carried out on coated speci...

In the past 10 years new and more accurate stellar neutron capture cross section measurements have changed and improved the abundance predictions of the weak s process. Among other elements in the region between iron and strontium, most of the copper abundance observed today ...
