Abstract
Four AI-xZn alloys (x = 8, 24, 40, and 48 at%) are studied from RT to 400-degrees-C by X-ray powder diffraction. The structure changes proce eding during heating are studied. They are in line with the phase diag ram. The most important result is that the lattice constant of the mat rix, a[alpha(M/P)], in contact with the various precipitates P occurri ng in this system, exhibits an unexpected behaviour only in case of fu lly coherent precipitates, i.e. Guinier-Preston zones; a[alpha(M/GPZ)] depends on the zinc content of the alloy.
