Si-B-O-N powder without B-O bonds synthesized by polymeric precursor were hot-pressed into ceramics at different temperatures. The variations of microstructure
A formula is derived for determining the influence of temperatureand loading rate on dynamic fracture toughness of a high strength low alloy steel (HQ785C) from
The hydration reaction of a mixture of tricalcium aluminate (C3A) and gypsum with the molar ratio of 1:3 was carried out at room temperature and a water/solid r
The present paper aims to the characterization of high rate direction solidification on Al-Mn and Al-Cu alloys. It is indicated that the relevant cooling rate o
