Characterization and Investigation of Grain Selection in Spiral Grain Selectors during Casting Single-Crystal Turbine Blades
Manufactured single crystal components using Ni-base super alloys are routinely used in the hot sections of aero engines and industrial gas turbines due to their outstanding high temperature strength, toughness and resistance to degradation in corrosive and oxidative environments. To control the quality of the single crystal turbine blades, particular attention has been paid to grain selection,...
متن کاملHigh-pressure structural studies of eskolaite by means of single-crystal X-ray diffraction
The structural behavior of Cr2O3 was investigated up to ~70 GPa using single-crystal X-ray diffraction under a quasi-hydrostatic pressure (neon pressure medium) at room temperature. The crystal structure remains rhombohedral with the space group R3c (No. 167) and upon compression the oxygen atoms approach an ideal hexagonal close-packing arrangement. An isothermal bulk modulus of Cr2O3 and its ...

متن کاملX-ray diffraction studies of protein crystal disorder
Protein crystals contain many kinds of disorder, but only a small fraction of these are likely to be important in limiting the diffraction properties of interest to crystallographers. X-ray topography, high-angular-resolution reciprocal space measurements, and standard crystallographic data collection have been used to probe three factors that may produce diffraction-limiting disorder: (1) solu...
متن کاملSingle Crystal Orientation Measurement by X-ray Methods
Semiconductor substrates made from single crystal materials need to be cut precisely along a fixed axis during the manufacturing process of the semiconductor components. Thus, measuring the crystal orientation is critical. For these measurements, Xray techniques demonstrate the highest precision. This report presents an outline of two popular X-ray diffraction techniques, the diffractometer and...
