____ can be added to improve hardness, strength, creep resistance, and corrosion resistance.
A) Carbon, chromium, and vanadium
B) Aluminum, silicon, and titanium
C) Potassium, sodium, and zirconium
D) Oxygen, argon, and nitrogen

Question

Quizplus · Accepted Answer

Carbon, chromium, and vanadium are all known to increase hardness, strength, creep resistance, and corrosion resistance in materials. Aluminum, silicon, and titanium can also improve certain properties, but they do not have the same universal impact as carbon, chromium, and vanadium. Potassium, sodium, and zirconium are not typically used as alloying elements in structural materials. Oxygen, argon, and nitrogen are also not typically added to improve material properties but may be present as impurities or as part of a manufacturing process.
