PART A. Definitions and Nomenclature (10 points-1 point each) 1. The maximum solid solubility on a phase diagram is controlled by factors described by Hume-Rothery . 2. The proeutectoid phase for a hypoeutectoid alloy (for an Fe-C alloy) ferrite . 3. The melting reaction that occurs in an alloy system in which there is no change in composition when the solid transforms to the liquid is referred to as congruent melting. 4. The rule that relates the number of degrees of freedom to the number of components, phases, and state variables is the Gibbs phase rule. 5. The phase boundary separating a single-phase liquid region from a two-phase liquid plus solid region is referred to as the liquidus . 6. When a liquid of one composition transforms to a liquid of another composition and a solid the reaction is said to be a incongruent melting . 7. The phase boundary separating a solid region from a two-phase solid region is the solvus . 8. On cooling, a liquid transforming to a liquid of a different composition and a solid is referred to as a monotectic reaction. 9.
