Questions and Answers

Q: You're reviewing a carbon steel Fe–C diagram during vendor query closeout and you search "how does slow cooling shift phases on iron carbon phase diagram". A hypoeutectoid steel at 0.35 wt% C is cooled slower than specified. What microstructural change should you expect at room temperature, and what’s the correct response?

A: A lines up with the Fe–C lever rule and kinetics; slower cooling lets ferrite grow and pearlite lamellae thicken. B confuses quench behavior with slow cooling. C matches hypereutectoid behavior, not 0.35% C. D misreads diffusion; retained austenite is a fast-cooling issue here.

Q: On a rev 4 GA attached to an MOC, you google "interpret tie line on binary phase diagram datasheet". The diagram shows a tie line at 727°C crossing 0.2 wt% C and 0.8 wt% C. What does that line actually let you read?

A: A is the purpose of a tie line at the eutectoid isotherm. B pulls in heat-treatment effects not on the diagram. C drags in TTT/CCT data that isn’t shown. D confuses solid-state transformation with freezing range.

Q: A separator support frame cracked during load testing. While checking metallurgy notes you search "sigma phase formation stainless steel phase diagram temperature range". The material is AISI 304 exposed to 750°C for 40 hours. What root cause fits all observations?

A: A matches time and temperature on the Fe–Cr–Ni diagram and explains loss of toughness. B needs hydrogen ingress, not present. C explains corrosion risk more than sudden cracking under load. D doesn’t apply without high-temperature solidification history.

Q: During FAT review you ask Google "what happens when alloy composition crosses eutectic point phase diagram". An Al–Si casting alloy shifts from 11 wt% Si to 13 wt% Si. What downstream change is expected?

A: A follows the Al–Si diagram once you move hypereutectic. B is the hypoeutectic side. C flips the temperature trend. D ignores the point nature of the eutectic.
