Questions: 1. Using our text or other reference, in Figure A: a. What is the melting points (in °C) for copper? 1085°C b. What is the melting points (in °C) for nickel? 1455°C c. At any temperature in the “L+SS” region, which phase (L or SS) has the highest composition of copper? The L-phase 2. The Aluminum-Silicon (Al-Si) phase diagram (Figure 9.13 in the text) is a fair approximation of the Eutectic Phase diagram shown in Figure B. a. What is the eutectic temperature for the Al-Si system? 577°C b. What is the eutectic composition for the Al-Si system? 12.6 wt % c. In general, below the eutectic temperature, what two solid phases exist? Pure silicon (β phase) and >95% pure aluminum (α phase). 3. Figure C shows a general Stress-Strain curve for a yielding material. a. What is slope 1? The elastic (or Young’s) modulus b. What is point 2? The yield strength c. What is point 3? The tensile strength d. What is point 4 compared to the strain value at failure? See notes on Figure C on following page. e. What is the physical significance of area 5? The area 5 is the “toughness”, the energy required for fracture
