Journal of Manufacturing and Materials Processing, 2018 It was found that the ultrasonic spot welding may serve as an efficient method to join relative large thin-walled parts made of fiber-reinforced thermoplastics. In this study, a new control method for the ultrasonic spot-welding process was investigated.

Hydrogen Analyses of FSW Cu‐OFP Tested Under Creep Conditions in Sulphide Containing Environment
Materials and Corrosion, EarlyView.Friction stir welded Cu‐OFP exhibits elevated creep rates in sulphide‐containing aqueous environments, with creep increasing as sulphide concentration rises. Hydrogen measurements indicate that sulphide exposure does not increase hydrogen content. ABSTRACT Friction stir welded oxygen‐free phosphorus‐doped copper (FSW Cu‐OFP) is a candidate material for

Propellants, Explosives, Pyrotechnics, EarlyView.There are multiple drivers for the development of reliable mechanical property techniques for high explosive (HE) samples, particularly smaller HE samples. While Vickers microhardness is a commonly used technique for mechanical characterization in metals and other materials, there has been little work using this technique for HE materials, particularly
