The peritectoid reaction A. produces a liquid from 2 solids B. produces a solid from 2 liquids C. produces 2 solid phases from a liquid D. is a reaction between a solid and a liquid forming a second solid E. is a reaction between 2 solids forming a third solid Both eutectic and eutectoid reactions A. involve a liquid phase B. produce a single phase reaction product C. involve a single phase decomposing to form two new phases D. can occur without solid state diffusion E. none of the above Solid solution strengthening A. results from removal of impurities from the metal B. depends on solute interaction with dislocations C. works if the solute atom is oversized but not undersized D. always improves toughness E. All of the above Which of the following planes are fully close packed? A. (110) in fcc and (111) in bcc crystals B. (100), (101) and (001) in fcc crystals __ C. (111) and (111) in fcc crystals D. all of above E. none of above The eutectoid reaction, on cooling, A. produces a liquid from 2 solids B. produces a solid from 2 liquids C. produces 2 solid phases from a liquid D. produces 2 solid phases from a third solid E. is not a diffusion controlled reaction
