Metals & Alloys

Scope

The semi-quantitative measurement of metals in various alloys is demonstrated using the Fundamental Parameters approach without the need for a reference library.

Background

Standard and specialty alloys vary in metal composition to give the alloy its specific physical, mechanical, and chemical properties. Analyzing alloy composition by XRF (X-ray Fluorescence) is important to ensure the proper alloy grade meets the needs for its specific use. The Rigaku NEX QC+ QuantEZ system gives the operator a quick, simple, and reliable means of checking alloy composition without damaging or changing the sample.

Model: NEX QC+ Quant-EZ

Results

*Mg and Si at low levels are not detectable in an aluminum alloy due to aluminum absorption of Mg and Si X-rays

*Trace levels of Ti and V and low levels of Co are not detectable in this alloy due to high levels of Ni and Mo that absorb transition metal X-rays

*Trace levels of Fe and Ni are not detectable in this alloy due to high levels of Cu that absorb transition metal X-rays

Conclusion

The NEX QC+ QuantEZ provides a rapid, non- destructive means for semi- quantitative measurement for screening, identification and other semi-quant needs without the need for a special library. To optimize the FP results for a specific family of alloys, the QuantEZ software also gives the user a simple way of creating a Matching Library using one more certified alloy sample of that family type, providing a fast and simple means to design libraries to fit exact analysis needs.
