Overview
SIST EN 24883:2000 specifies a standard solution method for the determination of metallic element contents in hardmetals using X-ray fluorescence (XRF). It is harmonized with ISO 4883:1978 and applies to a wide range of hardmetals, particularly those consisting of carbides and binder metals. This standard is essential for industries and laboratories focusing on the production, quality control, and analysis of powder metallurgy materials, ensuring accurate and consistent chemical analysis.
Key Topics
- Scope of Analysis: The standard covers the determination of the following metallic elements: cobalt (Co), iron (Fe), manganese (Mn), molybdenum (Mo), nickel (Ni), niobium (Nb), tantalum (Ta), titanium (Ti), tungsten (W), vanadium (V), and zirconium (Zr).
- Applicable Materials:
- Carbides of niobium, tantalum, titanium, vanadium, tungsten, and zirconium.
- Mixtures of these carbides with binder metals.
- Presintered or sintered hardmetals in all grades, including those produced from the materials above.
- Analytical Principle: Uses X-ray fluorescence spectrometry following a solution method, where samples are dissolved using hydrofluoric and nitric acid, then analyzed in solution form to minimize particle size and inter-element interference effects.
- Minimum Element Content: Each element analyzed must meet the minimum levels specified in the standard, ensuring the method's suitability for the relevant materials.
- Quality and Accuracy: The method emphasizes repeatability, calibration using reference standards, and meticulous sample preparation to achieve reliable results in metallurgical laboratories.
