Bestimmung von ONH in Legierungen: Optimierung von Zykluszeit und Leistung

Oxygen, nitrogen, and hydrogen are critical quality metrics in steel and nickel- and cobalt-based alloys, directly influencing strength, ductility, porosity, and embrittlement. Explore the principles of simultaneous ONH determination using the LECO ONH836, which employs a high-power electrode furnace to rapidly release and measure target gases. It also outlines best practices for sampling and sample preparation—particularly for hydrogen—to minimize diffusion losses and ensure compliance with ASTM and ISO standards.
