Unformatted text preview: 3. Solid Solution hardening, 4. Grain size refinement. 5. phase transformation. 6. Describe the difference between age hardening in nonferrous metals and martensite tempering in steels. 7. Describe the phases resulting from cooling along A, B, C, D lines in the CCT diagram of steel. Calculation: 1. For an alloy containing 50% Cu and 50% Ni, calculate the amounts of solid S and liquid L presents at 1300C. Show that the total nickel content in the solid and liquid phases adds up to 50%. 2. Calculate the relative proportions of phases in Cu-Ag alloy of eutectic composition, just below the eutectic temperature. During the cooling of an Alloy (Cu 80% Ag 20%) from 1100C to 600C, describe the phase transitions during the cooling (hint: there are two critical transitions)....
