Explain the mechanism of temper embrittlement.

Explain the mechanism of temper embrittlement! (How, what temperature, the impact of alloying element and how to avoid it)

2: We heat treated a 2205 duplex stainless steel at 1100°C resulting in ferrite/austenite content of 50-50%. The pitting resistance temperature is 80°C. We heat-treated another piece at 800°C for 10 min and the pitting temperature dropped to 60°C. As the composition of the alloys is the same, so we have the same PRE in the alloy.

a) Why do we have a reduction in corrosion resistance? Explain based on the PRE.

b) If we use the material in a corrosive environment and loaded condition, what types of failure are you expecting to occur?
