| Equipment | Application | Description | |
|---|---|---|---|
 Vacuum Arc Remelting Furnace (VAR) |
Vacuum melting of metals and preparation of samples for analysis | • Melts metal by generating an arc discharge between the electrode and the material to be melted • Enables melting of highly reactive materials under vacuum while minimizing contamination from gaseous impurities • Capable of melting high-melting-point metals |
|
 Universal Testing Machine (UTM) |
Analysis of mechanical properties of various materials | • Mechanical properties are measured by applying a load to both ends of the specimen • Various jigs can be used depending on the property to be measured • Equipped with tensile-test jigs and an extensometer for strain measurement • Maximum load: 200 kN (20,000 kgf) |
|
 Optical Microscope (OM) |
Analysis of metal microstructures and product defects | • An optical microscope that uses visible light and optical lenses to magnify and observe samples • Capable of analyzing metal microstructures and product defects • Magnification up to 500× • Sample preparation equipment for microscopic observation is available, including hot mounting and polishing equipment |
|
 OES Analyzer |
Quantitative analysis of metallic elements | • Metal composition analyzer using Spark-OES (Optical Emission Spectrometry) • Capable of quantitative analysis of metallic elements • Various certified reference materials are available to improve analytical accuracy |
|
 ON Analyzer |
Quantitative analysis of oxygen and nitrogen in metals and other inorganic materials | • Oxygen is measured using a wide-range infrared detector (IR), while nitrogen is measured using a thermal conductivity detector (TCD). • Inert gas fusion analysis is performed by melting the sample at temperatures approaching 3,000°C under an inert gas atmosphere with helium. The analytical gas stream is then purified and the resulting gas output is analyzed. |
