摘要：

The dependence of structural changes in precipitating Al-10 at% Li alloy on the annealing temperatures as traced by X-rays, electric resistivity and microhardness measurements revealed the formation and subsequent dissolution of Al-Li precipitates in the temperature range of 25-500 °C. The observed variations were attributed to the effect of the annealing temperature on the behaviour of Li atoms within the Al matrix. The increase of the Li concentration in the matrix due to the dissolution of Al-Li precipitates, being 3.75 at %, Li as obtained from X-ray measurements agreed well with the value 4.0 at % Li obtained from resistivity measurements. © 1979 with the authors.
