Question 1
According to European material standards (EN 1977 and EN 1652), which grade of copper is phosphorus-deoxidized with high residual phosphorus content, specifically optimized for seamless tube manufacturing, vessel fabrication, and thermal joining without risk of hydrogen embrittlement?
Correct Answer:
Cu-DHP (CW024A)
Question 2
What chemical and microstructural mechanism causes hydrogen embrittlement (Wasserstoffkrankheit) when welding or annealing oxygen-bearing copper grades like Cu-ETP (CW004A) in reducing gas atmospheres containing hydrogen above 400°C?
Correct Answer:
Atomic hydrogen diffuses into the crystal lattice and reacts with grain boundary cuprous oxide (Cu2O) to form high-pressure water vapor (steam) that ruptures grain boundaries
Question 3
Which brass alloy (Kupfer-Zink-Legierung) consists of a single-phase alpha solid solution, exhibits exceptional cold ductility for deep drawing and metal spinning (Drücken), and is standardly designated as Ms70 (CW505L)?
Correct Answer:
CuZn30 (CW505L)
Question 4
What is the recommended temperature range for recrystallization annealing (Rekristallisationsglühen / Weichglühen) of cold-worked pure copper (Cu-DHP) to restore ductility without inducing excessive grain coarsening (Grobrekornbildung)?
Correct Answer:
450°C to 650°C
Question 5
Under what environmental and metallurgical conditions are brass components containing more than 15% zinc most prone to stress corrosion cracking (Spannungsrisskorrosion / Saisonrissigkeit)?
Correct Answer:
Simultaneous presence of internal tensile residual stresses and an atmospheric environment containing ammonia (NH3) or amines and moisture
