Fire-protective fabrics made from high-performance fibers are available to provide protection from various hazardous conditions such as extreme heat and flame. However, these fabrics are often exposed to other deteriorating conditions, including moisture. It is a concern for the user's safety as...

Gomes, L.E., Spinelli, J.E., Bogno, A.-A., Gallerneault, M., Henein, H.

An experimental study is reported on heat treating rapid solidified Al-12 wt.% Si alloy with 355-425 m powder size. Fast heat treatments at 813K revealed morphological shifts of eutectic Si from the as-atomized condition to those after annealing. The Si network of the as-atomized samples showed...

The structural performance of microalloyed steel weld joints is essentially dependent on the microstructural characteristics of the heat-affected zone (HAZ). However, the microstructure is adversely impacted by the heat input of the welding process. As such, an X70 microalloyed steel was welded...

Mohammadijoo, M., Henein, H., Collins, L., Ivey, D.G.

Tandem submerged arc welding with an additional cold wire (CWTSAW) is being developed for pipeline manufacturing to improve productivity in terms of deposition rate and travel speed of welding. An appropriate understanding of the welding conditions to guarantee requisite weld geometry, appearance...

Interfacial nanodroplets were grafted to the surfaces of self-sacrificed template particles in a galvanic reaction system to assist the construction of 3D Au porous structures. The interfacial nanodroplets were formed via direct adsorption of surfactant-free emulsions onto the particle surfaces....
