This paper studies the influence of ammonia gas on wood color changes in response Concealers to an increasing demand for dark colored wood specimens.The darker wood color in ammonia fuming is accomplished through chemical reactions between ammonia gas and wood compounds.We exposed oak, maple, spruce, and larch wood samples to ammonia gas for 16 day
Cold dwell fatigue is a well-known problem in the titanium components of aircraft engines.The position-aids high temperature and low dwell stress of in-service conditions have been reported to give rise to dwell fatigue resistance through a thermal-mechanical alleviation process.Here, dwell fatigue tests at room temperature and the 1964-1973 Engine
