Observation of metallic tissue through chemical treatment.

You can gain clues about the quality of the product and investigate defects from the shape of the organization!

We will introduce the observation of metallic structures through chemical treatment. By performing chemical treatment on metallic samples, it is possible to clearly observe the metallic structure. Observing the structure can confirm the condition of the sample as well as the history of applied heat and stress, providing clues about the quality of the product and any defects based on the structural shape. In the published catalog, you can find details on the observation of metallic structures, such as the macrostructure of aluminum plates and the soldered parts of copper terminals. Additionally, we offer other services such as cross-sectional observation and various analysis services. Please feel free to contact us if you have any requests.

Introducing examples of aluminum welding observation. Internal observation through X-ray fluoroscopy and CT inspection allows for clearer observation after cross-section preparation!

Here are some examples of observations of aluminum spot welds. In internal observations using X-ray radiography, voids were observed inside the weld, and in internal observations using X-ray CT, it was confirmed that the voids are located near the center of the weld (between the two aluminum plates). Additionally, by creating a cross-section of the same sample and combining mechanical polishing with chemical etching treatment, we were able to observe the condition of the weld more clearly. 【Overview】 ■ Internal observation using X-ray radiography - Non-destructive testing and X-ray radiographic observation were conducted - Voids were observed inside the weld ■ Internal observation using X-ray CT - Non-destructive testing and X-ray CT observation were conducted - It was confirmed that the voids are located near the center of the weld ■ Cross-sectional observation using optical microscopy and tabletop SEM - Mechanical polishing and chemical etching A cross-section suitable for the sample allows for clearer observation. *For more details, please refer to the PDF document or feel free to contact us.

Introducing a case study on the cross-section preparation of a large sample (65mm × 28mm) and the observation of its internal structure!

We present an observation case of a large sample (expansion valve) measuring 65mm × 28mm. This sample uses magnetic materials, and due to distortion in the images during SEM observation, we primarily conducted observations using an optical microscope. From the appearance and X-ray radiographic observation, it was found that there are some areas that are not visible in the X-ray.

We will introduce an analysis example confirming that the welded area has a large distribution of grain crystals.

As a case study of EBSD, we conducted an analysis of the cross-section of an aluminum welding joint from the cross-sectional direction, which I would like to introduce. For a sample where an aluminum plate was spot welded to an aluminum case, we prepared a cross-section of the weld and performed EBSD analysis. In the distribution of grain sizes, it was confirmed that the weld area has a greater number of larger grains compared to the base material. [Analysis Overview] ■ Visualization of Grain Structure - It is evident that the shape and size of the grains in the weld area differ from those in the base material. ■ Distribution of Grain Sizes - It can be confirmed that the weld area has a greater distribution of larger grains compared to the base material. *For more details, please refer to the PDF document or feel free to contact us.

Investigation of the joint condition and joining methods of crimp terminals, as well as the types of materials! Introduction to cross-sectional observation and elemental analysis using SEM/EDX.

I would like to introduce the topic of "Cross-sectional observation of copper terminals and elemental analysis using SEM/EDX." We conducted cross-section preparation of the joint area of the copper crimp terminal fixture for resistance measurement, applied chemical etching to the prepared cross-section, and observed the metal structure before and after etching. As a result, we infer that the detected elements are P (phosphorus), Ag (silver), and Cu (copper), indicating that it is a silver-containing phosphorus copper solder material. *For more details, please refer to the PDF document or feel free to contact us.*

We will introduce an example of analysis using EBSD for screws (Cu2Zn).

The EBSD method allows us to confirm the distribution of crystal sizes and the orientation of crystal orientations. In this case, it was found that there is a significant orientation difference in the valleys of the screw, suggesting that there is a large residual stress. Additionally, it was observed that small crystal grains are distributed on the surface of the screw. [Summary] ■ Analysis Method - Observation of crystal structure using EBSD ■ Results - It was found that there is a significant orientation difference in the valleys of the screw - It is inferred that there is a large residual stress - It was also observed that small crystal grains are distributed on the surface of the screw *For more details, please refer to the PDF document or feel free to contact us.
