The Role of Chromia Volatilization During Oxidation of Ni-based Alloys in Static Laboratory Air Containing Ambient Humidity

This study demonstrates that even in static laboratory air without intentional water vapor, ambient humidity causes significant chromia volatilization in Ni-based alloy 725, a phenomenon that follows a modified paralinear model with weak temperature dependence and is often overlooked in oxidation research.

Influence of extraction methods on the mechanical properties, statistical homogeneity, and moisture regain of Hyphaene thebaica petiole fibers for composite reinforcement

This study demonstrates that while alkaline treatment yields the strongest and least hygroscopic Hyphaene thebaica petiole fibers, underground retting produces the most statistically homogeneous and mechanically reliable fibers, highlighting the critical influence of extraction methods on their suitability for composite reinforcement.
