Metallurgy Practice Exam
About Metallurgy Exam
The Metallurgy Practice Exam evaluates your ability to understand, analyse, and apply metallurgical principles to material selection, processing, and testing. This certification measures your knowledge of metal structures, phase transformations, alloy design, processing methods, corrosion behaviour, and characterization techniques. Passing demonstrates you can solve real‑world problems in metal production, fabrication, and quality control.
