Chromium phase in room temperature
WebAfter long exposure to temperatures in the range of 1,100-1,600°F (590-870°C), many of the higher chromium alloys precipitate a brittle intermetallic compound known as sigma phase. Molybdenum contributes to this phase. Sigma reduces room-temperature impact strength and ductility. The quantity and morphology of the WebJun 1, 2024 · Organic phosphors exhibiting room-temperature phosphorescence (RTP) in amorphous phase are good candidates for optoelectronic and biomedical applications. In this proof-of-concept work, a rational strategy to activate wide-color ranged and persistent RTP from amorphous films by embedding electron-rich organic phosphor into electron …
