The mechanical properties and corrosion resistance of the stainless steel (SS) corbel decline sharply after the welding process, which may cause serious accidents. Combining with microcharacteristics, mechanical properties, and corrosion properties,

Construction via post-tensioning (PT) has evolved over the past 60 y as an often preferred approach to affecting integrity for large concrete structures. In the case of bridges, tendon ducts typically contain multiple 15.24 mm (0.600 in) diameter, se

Grouted post-tensioning has evolved to become the construction method of choice for many structures, including bridges. However, instances of corrosion-induced fracture of wires and strands and failure of tendons have occurred as a consequence of eit

Heat treatment is applied to orthodontic wires to inhibit the fracture after the orthodontist manipulates them to make loops, helical springs, and arch forms. We tried to investigate the effect of heat-treatment conditions on the surface properties o

The primary water stress corrosion cracking (PWSCC) of Alloy 600 (UNS N06600), Type 304 (UNS S30400), and Type 316 (UNS S31600) stainless steels (SS) was studied at 360°C and at nominal st...

Acoustic emission (AE) can be used to monitor damage such as fracture and corrosion in situ. For AE from individual signal bursts produced by the corrosion process, the intensity of the AE energy and HIT (hit count) may be used potentially to grade t
