Subsampling Approaches for Compressed Sensing with Ultrasound Arrays in Non-Destructive Testing.

Full Matrix Capture is a multi-channel data acquisition method which enables flexible, high resolution imaging using ultrasound arrays. However, the measurement time and data volume are increased considerably. Both of these costs can be circumvented via compressed sensing, which exploits prior knowledge of the underlying model and its sparsity to reduce the amount of data needed to produce a high resolution image.

Microstructure and Mechanical Properties of Precipitate Strengthened High Entropy Alloy AlCoCrFeNiTi with Additions of Hafnium and Molybdenum.

High entropy or compositionally complex alloys provide opportunities for optimization towards new high-temperature materials. Improvements in the equiatomic alloy AlCoCrCuFeNi (at.%) led to the base alloy for this work with the chemical composition AlCoCrFeNiTi (at.
