One of the panel members received the following information from a researcher in the Czech Republic who works for the Research Institute for Metals and presented a paper about Al 8006 at the 1999 IMS convention:

"We really use Barker's reagent (4 to 5 ml fluoroboric acid in 200ml water), electrolytic anodizing at 20 to 22V during 90 to 180s and then we examine the samples under crossed polarizer and analyzer with sensitive tint."

She also sent along the following preparation procedures for other aluminum alloys:

"We use the most often cold mounting in acrylic compounds, wet grinding on SiC papers - the usual set is P220, P500, P800, P1200, then coarse polishing on diamond suspensions - 7, 3 and 1 microns and final polishing on silica suspension (Buehler MASTERMET 2).
The etchants we use more frequently for macroetching are:
- Tucker's reagent: HCl - 45 ml, HF - 15ml, HNO3 - 15 ml, H2O - 25 ml
- 10 to 20% aqueous solution of NaOH followed by rinsing in 50% aqueous solution of HNO3
- diluted Tucker: 300 ml HCl, 300 ml HNO3, 5 ml HF, 300 ml H2O
Microetching reagents:
- 0.5% aqueous solution of HF
- 30% aqueous solution of HNO3
- Dix-Keller reagent: 1 ml HF, 1.5 ml HCl, 2.5ml HNO3, 95 ml H2O"
