A Flashcards
(15 cards)
energy required to increase a mole of a material by a unit T
Heat Capacity
energy is stored as atomic vibrations
Heat Capacity
the size of a material changes with a change in temperature
coefficient of thermal expansion
the ability of a material to transport heat
Thermal Conductivity
the ability of a material to rapidly cooled and not fracture
Thermal Shock Resistance
Four Strategies for Strengthening
Reduce Grain Size
Form Solid Solutions
Precipitation Strengthening
Cold Work
deformation at room temperature
Cold work
reduction of dislocation density by annihilation
Recovery
new grains are formed
Recrystallization
deformation above room temperature
Hot working
defects that allow for plastic deformation
Dislocations
material’s abilty to absorb heat
Heat Capacity
single quantum of vibrational energy
Phonon
refers to when materials may experience fracture due to dimensional changes
Thermal Shock
Stress due to temperature
Thermal stress
