Coloration Defects in Industrial-Grade Zirconium Sponge
Microscopy and Microanalysis
Zirconium alloys -- Defects, Zirconium alloys -- Testing
As a widely applicable alloying material, zirconium is an essential part of many industries (aerospace, nuclear engineering, precision machining, etc.) and is often demanded in high purity. A systemic study was therefore launched in order to combat a trace-level coloration defect discovered in industrial-grade zirconium sponge. The wide variety of morphological features and coloration effects presented by the defect films (iridescent blue/purple, mosso/olive green, brown, brick, red, golden/straw, etc.) which are observed concurrently makes traditional microscopy and spectroscopy an ideal avenue for investigating the composition and formation mechanisms of the films.
