discontinuous precipitation

[‚dis·kən′tin·yə·wəs prə‚sip·ə′tā·shən]
(metallurgy)
Precipitation principally at and away from the grain boundaries in a supersaturated solid solution; diffraction patterns show two lattice parameters, the solute in solution and the precipitate.

For instance, Al alloys bearing up to 30 wt.% Zn can attain discontinuous precipitation at 75[degrees]C, 100[degrees]C, and 150[degrees]C [9].
This is called discontinuous precipitation. In this process the precipitated regions generally grow from the edges of the grains and consume the crystal progressively.
Some paper subjects are defect analysis in semiconductor materials based on p-n junction diode characteristics, electronic structure and doping effects of Ni and Co on a kink in the edge dislocation of BCC iron, peculiarities of discontinuous precipitation in the Pb-Sn alloy, and local vibrational modes of Zn-H-P in GaP, InP, and ZnTe.
