Multimodal Data‐Driven Microstructure Characterization

Advanced Engineering Materials, EarlyView.
A self‐consistent autonomous workflow for EBSP‐based microstructure segmentation by integrating PCA, GMM clustering, and cNMF with information‐theoretic parameter selection, requiring no user input. An optimal ROI size related to characteristic grain size is identified.

Reflection and structural characteristics of semi-bright and mirror bright nickel coatings [PDF]

Journal of the Serbian Chemical Society, 2002
The reflection and structural characteristics of the nickel coatings obtained in the presence of a basic brightening addition agent only, and of both a basic and top brightening addition agent are examined. It is shown that the nickel coating obtained in

Characterisation of metal mirrors on GaAs

Electronics Letters, 1996
The authors describe a Fabry-Perot technique for determining the reflectivity and the phase of the interface between semiconductor and a multilayer metal structure as it will be realised in actual device fabrication. The reflection coefficients of GaAs to Ti/Au, Pd/Au, Au and Ag interfaces are measured at 1.55 /spl mu/m.

Slip Localization Intensification Mediated by Grain Boundary Sliding in a Polycrystalline Nickel‐Based Superalloy

Advanced Engineering Materials, EarlyView.
The temperature dependence of fatigue behavior in nickel‐based superalloys is investigated through high‐resolution measurements of plastic localization. While increasing temperature reduces localization and enhances fatigue performance in René 88DT, Inconel 718 exhibits a sharp degradation at intermediate temperature due to intensified slip ...

High‐Temperature Nanoindentation of Metals: Assessing Thermal Drift, Frame Compliance, and Chemical Composition Effects on the Reported Mechanical Properties

Advanced Engineering Materials, EarlyView.
Do not let thermal drift and instrument artifacts deceive high‐temperature nanoindentation results. We compare classical Oliver–Pharr and automatic image recognition analyses across steels and a Ni alloy to quantify these effects. Accounting for artifacts reveals systematic softening with temperature, while Cr and Ni additions boost resistance ...
