Unformatted text preview: e strain at 400 N (8 points)
Consider the phase diagram below. An alloy containing 40%Ag is slowly
cooled from 1100 C to just below 780:
(a) What is the percentage of liquid phase present at 850 C? (6 points)
(b) What is the percentage of eutectic alpha phase at 780 – Δt? (9 points)
(d) What is the percentage of eutectic beta phase at 780 – Δt? (9 points) I)
II) a) Yield stress: 50.0 MPa, b) true strain: 0.049
a) %L= 73%, b) eutectic alpha phase: 11.6%,
c) eutectic beta phase : 38.5% Question 3:
Consider the steel phase diagram below: (45 points)
IV) A steel at a...
