  • Mô tả: Experimental data on the coarsening of precipitates and dispersoids in aluminium-based matrices are reviewed. Available data are tabulated as K =( r 3 − r 0 3 )/ t where r 0 is the initial particle radius and r is its value after time t at temperature T , and then plotted as log ( KT ) against 1/ T for consolidation and assessment. The considerable body of data for δ′-A 3 Li in Li-containing alloys is well represented by K =( K 0 / T ) exp (− Q/RT ) with K 0 =(1.3 −0.5 +3.0 ) × 10 −13 m 3 Ks −1 and Q =115±4kJ mol −1 . The relatively limited data for θ′ and θ″ in Cucontaining alloys are representable by the same relationship with K 0 ∼4 × 10 −8 and — 4 × 10 −10 m 3 Ks −1 , respectively, and Q — 140 kJ mol −1 . Available data for coarsening of L1 2 − Al 3 (Zr, V) and related phases in Zr-containing alloys and of Al 12 Fe 3 Si and related phases in Al-Fe based alloys indicate (i) rates of coarsening at 375 to 475 °C (0.7 to 0.8T m ) five to eight orders of magnitude less than would be expected for δ′, θ′ and θ″ in this temperature range, and (ii) high activation energies of ∼300 and 180 kJ mol −1 , respectively.
