Document Summary
) lever rule (or inverse lever rule) can be used to calculate the mass fractions of different phases in a phase diagram. size. ) common variables for phase diagrams include composition, pressure, and temperature. ) fast nucleation and slow growth result in a final product with coarse grains (relatively big grain. ) it is possible that phase transformations do not involve diffusion. ) the stainless steels are highly resistant to corrosion (rusting) in the ambient atmosphere, due to the predominant alloying element of cr. systems. ) in the crystal structure of nacl, na+ cations form fcc structure. ) porosity in a ceramic material will increase the young"s modulus of this ceramic. ) plastic deformation of crystalline ceramics is a result of dislocation motion. ) the brittleness of crystalline ceramics is explains, in part, by the limited number of operable slip. Short answer: for a ternary system, three components are present; temperature is also a variable.
