Analysis and Quantification of Non-metallic Inclusions in Steel

1 Oct 2017

Steel is one of the most important structural materials and its global production has shown a tremendous increase over recent years. In 2007, approximately 1.344 billion tons of steel were sold in the marketplace with new manufacturers entering the market to meet the growing demands. To ensure that the steel fulfills its application requirements, quality control has gained importance as the market offers a wider range of products than in the past

X-Ray Diffraction and SpectroscopyX-Ray diffraction & spectroscopy are used in material characterization to discern the structure and elemental composition of a sample. X-Ray diffractometers (XRD) are superior instruments in elucidating the dimensional atomic structure of crystalline materials, including powders, thin films and single crystals. For large unit cells or ordered macromolecules, consider small-angle X-ray scattering (SAXS). X-ray spectroscopic techniques include X-ray fluorescence (XRF) and X-ray photoelectron spectroscopy (XPS), both providing simple and accurate methods for determining the elemental composition of a material. Energy dispersive (EDXRF) and wavelength dispersive (WDXRF) XRF spectrometers are available, as well as handheld/portable devices. High-resolution, 3D microstructure characterization of materials can be achieved with X-ray microscopes combining sub-micron resolution imaging with 3D computed tomography.

Multiple tecchniques are available for determining particle size, shape and count including dynamic light scattering (DLS), laser diffraction, electrozone (Coulter technique), imaging particle analysis and single particle optical sensing. Determine the density of your material with a gas pycnometer or examine its surface area and porosity with gas adsorption analyzers and mercury porosimeters.

Properties such as porosity, strength, hardness, permeability, separation selectivity, corrosion, and thermal stress resistance can all be directly correlated to the porous structure of a material.Light MicroscopyLight microscopes or optical microscopes are used to visualize microscale objects under magnification, including cells, clinical specimens and materials. Lab equipment for light microscopy includes confocal microscopes, fluorescence microscopes, zoom and stereo microscopes. Microscope slides and imaging reagents are available for visualizing samples, as well as various microscope stages and incubators for large or temperature-sensitive samples. Find the best light microscopes in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Electron MicroscopyElectron microscopes (EM) are used to create high-resolution images of samples at the nanoscale by means of an accelerated beam of electrons as a source of illumination. Types of electron microscope include scanning electron microscopes (SEM), transmission electron microscopes (TEM), scanning transmission electron microscopes (STEM) and cryo-electron microscopes. Focused ion beam (FIB) microscopes are useful for modifying or milling a sample surface with nanometer precision, as well as imaging.

Quality control is a monitoring procedure or set of procedures that are put in place to ensure that a manufactured product adheres to a defined set of quality criteria. MicroscopyMicroscopy is a technique used to observe small objects in detail, from cells to materials, using light or electron microscopes. It enables researchers to examine structures with high resolution, aiding in fields such as biology, medicine, and materials science. With advanced microscopy techniques, scientists can gain insights into cellular processes, tissue structures, and material properties.
