The sample then was investigated using weight change measurement analysis and X-ray diffraction (XRD) analysis to study the weight gained and the phase oxidation that occurred. The weight gained of the titanium alloy was higher in molten salt environment compared to stainless steel due to the rapid growth in the oxide scale but showed almost no Author: Azila Baharum, Norinsan Kamil Othman, Emee Marina Salleh. Oxidation of Ta% W was studied in the temperature range deg C. Thermogravimetric studies of oxidation rates and x-ray diffraction, and metallographic and microhardness studies on oxidized specimens were made. The oxidation constitutes oxide formation and oxygen dissolution in the alloy core.

X-ray diffraction is a useful and powerful analysis technique for characterizing crystalline materials commonly employed in MSE, physics, and chemistry. This informative new book describes the principles of X-ray diffraction and its applications to materials characterization. It consists of three pa. Advantage: The x-ray diffraction provides a qualitative, a semi-quantitative and in some cases also a quantitative determination of crystalline substances. In conservation and restoration, it delivers particularly good results for the study of pigments, salts, rock .

An X-ray diffraction study of corrosion products from low carbon steel AX. Morales* Abstract It was found in earlier work a decrease in the corrosion rate from low carbon steel when it was subjected to the action of a combined pollutant concentration (S04^~ = 10"^ M + Cl" = X 10~^ M). It was also found that large magnetite content of. X-ray powder diffraction (XRD) represents the method of choice for the analysis of corrosion products, as it is the only analysis method that readily provides information about the phase-composition of solid materials. For example, a mixture of F e 3O 4 (magnetite).

A layer-by-layer x-ray diffraction phase analysis was made of the scale formed on Ni3Ti during atmospheric oxidation over the temperature range –°C. The scale was found to contain the oxides NiO, NiO TiO2, TiO2 (rutile), Ti3O5, and Ti2O3 as well as two nickel phases — “pure” nickel and a nickel solid solution.

The pattern of distribution of these phase constituents in Cited by: 2. A study was made of the phase composition of the scale forming on Ni3(Al + 15 at.% Ti) and Ni3(Al + 5 at.%Ti) alloys during atmospheric oxidation at temperatures ranging from to °C.

The scale was found to contain the oxides NiO, TiO2 (rutile),γ-Al2O3, NiO TiO2, NiO Al2O3, Ti3O5, and Ti2O3 together with Ni and a nickel base solid solution (Niss).Cited by: 2. In this, the only book available to combine both theoretical and practical aspects of x-ray diffraction, the authors emphasize a "hands on" approach through experiments and examples based on actual laboratory data.

Part I presents the basics of x-ray diffraction and explains its use in obtaining structural and chemical information. In Part II, eight experimental modules enable the students to 5/5(4).

X-ray crystallography (XRC) is the experimental science determining the atomic and molecular structure of a crystal, in which the crystalline structure causes a beam of incident X-rays to diffract into many specific directions.

By measuring the angles and intensities of these diffracted beams, a crystallographer can produce a three-dimensional picture of the density of electrons within the.
