[Analysis Case] Investigation of Damage to Heat Transfer Tubes Made of SUS316

[Analysis Case] Investigation of Damage to Heat Transfer Tubes Made of SUS316

Investigation of the cause of malfunction! Introducing a case study on the investigation of the heat exchanger components of the electric furnace dust reduction equipment.

We would like to introduce a case study on the investigation of the damage to the tube sheet of the heat exchanger component made of SUS316 in the electric furnace dust reduction equipment conducted by our company. Cracks observed around the tube sheet welding bead exhibited characteristics of typical intergranular stress corrosion cracking in the microstructure. The wet chemical composition of the adhered dust revealed a chlorine content of 15% and a moisture content of 8-9%. It was concluded that measures such as reducing residual stress through stress relief annealing are necessary when using SUS316. [Investigation Results] - A microstructure exhibiting characteristics of typical intergranular stress corrosion cracking was observed. - The crack initiation point was identified as intergranular stress corrosion cracking originating from pitting. - The crack propagation area showed a quasi-cleavage fracture surface. - The air inlet side exhibited severe cracking, while no cracks were found in areas with higher temperatures. *For more details, please refer to the related links or feel free to contact us.*

Quantitative evaluation of quenching microstructure using EBSD.

Quantitative evaluation of quenching microstructure using EBSD.

Quantitative evaluation of the hardened structure is possible using EBSD.

Due to the different crystal structures of martensite and austenite, it is possible to evaluate the phase distribution and quantitatively assess the area fraction of residual austenite using EBSD. Additionally, there is a specific crystallographic orientation relationship between martensite and austenite. Therefore, by reconstructing austenite from the crystallographic orientation measurement results of martensite, it is possible to measure the old austenite grain size. This method is also effective for materials that are difficult to etch.

Evaluation of transmittance and yellowness (yellow degree) using a color difference meter.

Evaluation of transmittance and yellowness (yellow degree) using a color difference meter.

Digitizing transparency and color into numerical data! Objectively evaluating transparency rate and yellowing degree!

This introduction covers the evaluation of transmittance and yellowing (yellowness) using a color difference meter. By making the product's constituent materials transparent and richly colored, necessary functional characteristics, artistic qualities, and design elements for the product's application are imparted. However, yellowing (discoloration) can occur due to the environment in which they are used, potentially compromising those characteristics. By quantifying transparency and color not through human perception but as numerical data, objective evaluation becomes possible. 【Overview】 ■ Principles of color difference measurement and acquired data (XYZ Yxy color space) - Light emitted from a light source passes through a transparent sample, and within an integrating sphere box, data on the transmitted wavelengths (transmittance) and converted color space data are obtained. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case of particle size measurement of cathode active materials using laser diffraction conducted by our company. In air or liquid, laser light is irradiated onto particles, and the angular dependence of the intensity of light scattered by the particles is measured. The angular dependence of the scattered light intensity is measured, and from that data, the particle size distribution (particle size distribution) is calculated. Commercially available reagents were used as samples, and measurements were conducted in a dry state without dispersing in a solvent. The particle size measurement results for NMC oxide showed a monodisperse state with particle sizes below several tens of micrometers, and the median diameter was calculated to be 12 μm. 【Case Overview】 ■ Measurement Method ・Dry ■ Particle Size Measurement Results for NMC Oxide ・Monodisperse state with particle sizes below several tens of micrometers ・Median diameter is 12 μm *For more details, please refer to the PDF document or feel free to contact us.
