The effects of applied tensile stresses on the temperature dependence of 10 MHz ultrasonic longitudinal velocity have been studied in three types of commercial aluminum alloys, 6064-T4, 2024-T351, and 3003-T251. In all measurements, it is found that the velocity decreases linearly with temperature, and the slope of the linear relationshi'p changes considerably as a function of applied tensile s...

Atmospheric corrosion of aluminum aircraft structures occurs due to a variety reasons. A typical phenomenon leading during operation is the deliquescence salt contaminants changes in ambient relative humidity (RH). Currently, controlled through scheduled inspections. In contrast, present contribution aims continuously monitor atmospheric using acoustic emission (AE) method, which could lead str...

Coating plays a significant role in surface engineering, which leads to the improvement of the mechanical and metallurgical properties of products. It also brings about economic benefits thanks to the cost savings of the improved properties of the surface of a product in particular. Friction surfacing is a relatively new way to create a homogeneous, fine-grained coating with amended resistance ...
