Pb – Sn PHASE DIAGRAM. EXPERIMENT # 9 Instructor: M.Yaqub. SOLUTION. Solid solution : Consists of atoms of at least two different types Solute an element or compound present in a minor concentration Solvent an element or compound in greater amount; host atoms.
Phase Diagram. DEVELOPMENT OF MICROSTRUCTURE IN EUTECTIC ALLOYS. Depending on composition, several different types of microstructures are possible for the slow cooling of alloys belonging to binary eutectic systems. These possibilities will be considered in terms of the lead–tin phase diagram .
Phase Diagram. Is a graphical representation of the conditions of temperature and pressure at which solids, liquids and gases exist. It may exist either as single phases or states of matter or two or more phases in equilibrium with one another. Phase Diagram for Iodine. Phase Diagrams.
Phase Diagram. Is a graphical representation of the phases of a substance as a function of temperature and pressure. Consists of three discrete regions that represent different phases (s, l, or g) exhibited by a substance
Phase Diagram. Development Of Microstructure. DEVELOPMENT OF MICROSTRUCTURE IN ISOMORPHOUS ALLOYS Equilibrium Cooling. Cooling occurs very slowly, in that phase equilibrium is continuously maintained.
Phase diagram. Need to represent how mineral reactions at equilibrium vary with P and T. P-X stability and mixing. Gibbs Phase Rule. The number of variables which are required to describe the state of a system: p+f=c+2 f=c-p+2 Where p=# of phases, c= # of components,
Phase Diagram. EUTECTIC SYSTEMS. EUTECTIC SYSTEMS. Many pair of elements and compounds are unlikely to satisfies complete solid solubility. Size difference up to 15% A very small amount of any component will always dissolve in any other components.
Phase Diagram. Module III. Introduction. Limitation of pure metals Need of alloying. Solid Solution. Metals generally form homogeneous liquid state
Solidification of Pb-Sn Alloys. Teri Mosher University of Illinois Advisor: Professor Krane. Presentation Overview. Dendrites Purpose Procedure Results. Dendrites . Primary Phases First phase to solidify Solid structures that form from a liquid Solidify in a branched style.
