Technical aspects

Acoustic emission (AE) acquisition system for monitoring of damage during processing and application of materials, e.g., during mechanical testing. System is equipped with four VS 600-Z2 piezoelectric AE sensors (400–800 kHz and ? 4.7 mm). Four parametric channels can be used to record external sensors (e.g, load cell, extensometer, thermocouple, etc.). Software for data acquisition (data streaming, feature extraction and/or transient recorder) and advanced data analysis is included. Possibility to quantify and localize AE events in 1-3-D, as well as frequency analyses of the measured signals.
In-situ capabilities

Continuous measurement of samples during mechanical test or health monitoring of components during service at different conditions. Normal operating temperature range: -40°C to +110°C. Possibility of performing tests at extreme temperatures (from cryogenic to up to 1200°C) by using AE wave guides.
Correlated workflow

AE measuring system can be combined with 3D X-ray microscopy (XRM) for advanced in-situ analysis of materials. AE allows for the precise detection of when microstructural changes take place and quantification of damage, while XRM provides 3D microstructural information.
Additional measurement possibilities

Classification of AE signals using machine learning approaches give quantitative information of in-situ microstructural changes.
