Moire interferometry by reflection is described and demonstrated for the case of a real reference grating of 1200 lines/mm. Extraneous beams can be displaced and stopped by using a wedge-shaped air gap between reference and specimen gratings. Double-

The diffusion of Ni and Cr into TD-NiCr has been studied over the 900 to 1100 C temperature range. The diffusion couples were prepared by electroplating Cr and Ni on polished TD-NiCr wafers. Concentration profiles produced as a result of isothermal d

A nondestructive x‐ray diffraction technique has been developed to analyze small diffusion zones. This technique constitutes a new approach to the study of one‐dimensional volume diffusion and only requires intensity measurements from two differe

X-ray diffraction methods for studying solid-state diffusion are reviewed. Because of the lack of penetration, such methods are suited for diffusion zones spanning only a few microns. Most involve analyses of one, or more, (hkl) “band” of intensi

An x‐ray diffraction technique is described which may be used to determine the composition profile of small diffusion zones as well as the diffusion‐generated substructure. Thus far, this technique is restricted to volume diffusion and has been a

The moisture absorption/desorption behavior of resin matrix composites was mathematically modeled by classical diffusion theory using an effective diffusion coefficient. Good agreement was found between calculated moisture content and published data
