Surface Hardness Measurment and Microstructural Characterisation of Steel by X-Ray Diffraction Profile Analysis

An X-ray diffraction line will broaden considerably when steels change into martensitic structure on quenching. The results presented in this paper show that X-ray diffraction technique can be employed for a rapid and nondestructive measurement of hardness of hardened steel. Measurement on various quenched and tempered steels showed that the breadth of its diffraction peak increased with increa...

Surface X-ray speckles: coherent surface diffraction from Au(001).

We present coherent speckled x-ray diffraction patterns obtained from a monolayer of surface atoms. We measured both the specular anti-Bragg reflection and the off-specular hexagonal reconstruction peak for the Au(001) surface reconstruction. We observed fluctuations of the speckle patterns even when the integrated intensity appears static. By autocorrelating the speckle patterns, we were able ...

Surface analysis of dental amalgams by X-ray photoelectron spectroscopy and X-ray diffraction.

OBJECTIVES It is important to characterize the surface of dental amalgam in order to understand the process of mercury release from amalgam restorations in the oral cavity. The mercury evaporation occurs not only from the newly made restoration but also from the set material. METHODS The surfaces of four different types of amalgams, which had been well set, were analyzed with X-ray photoelect...

The Surface Structure of Model Catalyst in Action Investigated by X - ray Diffraction

C8 The high accuracy to the angular change of a crystalline specimen was applied to the studies of strain in multilayers [3]. And then, many strain measurements at the interfaces of various multilayer materials have been successfully conducted. Recent years, strain analysis can be conducted using automatic analysis programs, which take account of dynamical diffraction effects [4]. In the presen...

Surface structure of a neat ionic liquid investigated by grazing-incidence x-ray diffraction.

Grazing-incidence x-ray diffraction measurements were carried out to observe the surface structure of [bmim][PF(6)]. At an incident angle of less than the critical angle, a diffraction pattern from 10 nm beneath the surface was obtained. A broad Debye-Scherrer ring was observed in the diffraction patterns, indicating that the [bmim][PF(6)] molecules near the surface are randomly orientated, sim...
