Engineering Q3

TermDefinition
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

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
