Single crystalline Cu and α-Al2O3(sapphire) with different crystallographic orientation relationships at the interface were diffusion-welded in vacuum with and without a thin film Nb intelayer Effects of the orientation relationship at the interface on the fracture energy of Cu/Al2O3, and Cu/Nb/Al2O3, diffusion-bonded joints were studied.

Automatic calculations on the crystal orientation and angles needed for directional cutting on the samples can be made through the application of the electronic spreadsheets.

The effects of different growth conditions on crystalline orientations and surf-ace morphology of MgO thin film are discussed.

X-ray diffraction of these films revealed that the crystalline orientations of the CeO 2 films grown at low oxygen pressures were (111) orientation,while that grown at a relative high oxygen pressures possessed (100) orientation.

The effects of different growth conditions on crystalline orientations and surface morphology of MgO thin film arc discussed.

Effect of crystal orientation of black plate on the corrosion resistance of tinplate was studied by measuring the crystal orientation of black plates and the ATC value of tinplates,and the mechanism was also discussed.

The effect of electroplating condition on corrosion resistance and crystal orientation of zinc plating was investigated by the means of salt spray test (SST) and X\|ray diffraction (XRD).

The microscopic observation of directional crystallization of transparent organic melt of mixed dichlorobenzene (DCB) is made to study the interface morphology of growing crystal, the pattern of crystal growth and the cause of impurity inclusion.
