of the equilibrium a and y mixtures produced by long annealing at 400Β°C. It can be seen that the peaks resulting from the mergers in the tempered martensite pattern have roughly the same angular position as those in the pattern from cold-worked filings; i.e. peaks 3 and 4 approach the position of th
Since the discovery of age-hardening phenotnenon in aluminium alloys iiiany works have been carried out to elucidate inechanism of the precipitation processes and i t has been shown that the clustering of solute atoms on the matrix lattice or formation of the G.P. zones is the most important process
