Quantitative texture analysis in the Texture plugin of SmartLab Studio II

Keigo Nagao and Akito Sasaki

The presence of crystallographic texture (preferred orientation) in polycrystalline materials has a significant effect on the anisotropy of the properties of these materials. That means that quantitative description of the orientation distribution of crystallites, or the orientation distribution function (ODF), is an important task for materials characterization and prediction of...

Advanced ZSX Guidance—Semi-quantitative analysis (SQX analysis)

Yasujiro Yamada

Wavelength dispersive X-ray fluorescence (XRF) spectrometers have high spectral resolution and can therefore identify peaks with high accuracy. However, if the analysis line overlaps with a higher order line, peak identification and semi-quantitative analysis results may not be reliable. To perform accurate analysis for such cases, measurement conditions that reduce...

Determination of refractory products with the XRF quantitative application package

Wataru Matsuda and Takao Moriyama

Refractory products are materials that can withstand high temperatures, above 1500°C. They are used in a wide range of applications, including as the lining of furnaces that perform melting and heating processing of materials for metallurgical, chemical, ceramic, machine, glass industries and so on. There are many types of refractories...

Examination of electronic components with the nano3DX X-ray CT microscope

Yoshihiro Takeda

X-ray computed tomography (CT) is a nondestructive imaging technique that can be used to examine the internal features of an object in three dimensions (3D). The first commercial X-ray CT scanner was introduced 45 years ago and the technique has been widely used in the medical and industrial fields since...

Identification of hazardous compounds and illicit drugs with the handheld Raman spectrometers

Taro Nogami

Raman spectrometry is becoming a common method for identification of hazardous compounds and illicit drugs. Historically, infrared absorption spectroscopy was the common method, but the mainstream has gradually shifted to Raman spectroscopy. In particular, Raman spectrometry has a couple of advantages over infrared spectrometry for onsite rapid analysis. First, handheld...

Basic principle and operation methods of the direct-derivation method

Hideo Toraya

Quantitative phase analysis (QPA) using the X-ray diffraction technique is routinely employed to find weight ratios of individual component phases in a mixture. Techniques for QPA have been widely used not only in research and development but also routinely deployed for quality control of industrial products. Various techniques have been...
