TL;DR: In this article, the effects of sintering parameters on the microstructure and tensile properties of in situ TiB whisker reinforced Ti6Al4V composites with a novel network architecture were investigated.

TL;DR: In this article, offset positioned thermal imaging of online TIG welding is demonstrated to be a feasible nondestructive monitoring technique for detecting porosities in the AA2219 welding, and spatio-temporal temperature distributions close to and in the vicinity of the weld pool can provide statistically distinct features in defect-free and defective weld regions, and thermal image-based assessment compares very favorably with post-weld radiography assessment for significant defect occurrence.

TL;DR: In this article, the use of non-linear ultrasonic techniques for the characterization of material degradation in 99.98% pure copper due to high-temperature creep was described, where flat dog-bone-shaped specimens were subjected to constant load creep testing at different stress and temperature levels.

TL;DR: In this article, an improved magnetostrictive sensors (MsSs) were used for structural health monitoring (SHM) of hard-to-inspect pipes using polymeric magnetic tape material that is suitable for use in a variety of industries.

TL;DR: In this article, a new compact sensor configuration comprising a single transmitter and multi-receivers (STMR) is presented for the in situ structural health monitoring (SHM) of large plate-like isotropic structures.
