Question 1
What are the primary alloying elements in AISI 4130 alloy steel commonly used in aircraft structural tubing?
Correct Answer:
Chromium and Molybdenum
Question 2
What is the primary difference between full annealing and normalizing heat treatments of aircraft carbon and alloy steels?
Correct Answer:
Normalizing cools the steel in still air, producing a slightly harder and stronger structure than full annealing which cools slowly in the furnace
Question 3
Which surface hardening process introduces nitrogen into the outer layer of alloy steel parts such as engine crankshafts without requiring subsequent quenching?
Correct Answer:
Nitriding
Question 4
When performing a Rockwell hardness test on hardened high-strength aircraft steel on the Rockwell C scale (HRC), which indenter and major load are used?
Correct Answer:
120° diamond brale cone with a 150 kg major load
Question 5
Which category of stainless steel contains approximately 18% chromium and 8% nickel, is non-magnetic in the annealed state, and cannot be hardened by thermal heat treatment?
Correct Answer:
Austenitic stainless steel (300 series)
