Engineering Q3

Dislocation defect Results from an incomplete later of atoms in a crystal structure. Dislocation can cause weakness in a structure as the application of stress will move the dislocation and result in early failure
Substitute defect An aton of another element is present in the crystal lattice. Distortation occurs if this atoms is larger or smaller than that if the parent elemtnt.
Vacancy defect IF there is an atom missing from the lattice, a distortion occurs as other atoms are forced toward the vacant space
Interstitial A different type of atom moves into the spaces between the atoms of the lattice
Liquidus line The Beginning of solidification
Solidus line The end of solidification
Liquid region Two metals are soluble in a liquid state
Solid Region Two metals are soluable in a solid state ( Solid solution )
Pasty Region Between the liqiudius and solidus lines, the alloy system is in a partly liquid and partly solid state
Eutectic Point A change point in which the alloy changes from liquid to solid without going through a pasty phase
Liquid The two metals are soluble in each other in the liquid state
Solvus line The transition line from one solid from to another solid form of an alloy
Solid Solution Both metals are completely dissolved in each other. Appear as one metal
Cooling Curve Highlights the start and end of solidification for a particular alloy. These points are then tranfered to a thermal equilibrium diagram
Dendritic growth Stages of crystal solidification of a metal from the liquid phase.As the metal cools,solidification starts from cells & begins to grow to form a dendrite.Have a tree-like formation with branches reaching out in all directions. Grain boundaries are formed.
Age Hardening When the aluminium/copper alloy, Duralumin is quenched around 375*C, it increases in hardness over time at room temperature
