WebThe thin-walled airfoil areas of as-cast single-crystalline turbine blades made of CMSX-4 superalloy were studied. The blades were produced by the industrial Bridgman technique at withdrawal rates of 2, 3 and 4 mm/min. The angle between the [001] crystallographic direction and blade axis, related to the primary orientation, was defined by the Ω … WebAug 29, 2003 · Introduction. Bone mineral is structurally related to the naturally occurring geologic mineral, hydroxyapatite (HA), differing in crystal size, perfection, and the nature of included impurities. Wide-angle X-ray diffraction (XRD) shows bone mineral diffraction maxima at the same positions as those of HA, but the peaks are less sharp and broader ...
