A CONTINUOUS HEAT TREATMENT PROCESS FOR IMPROVING THE PHYSICAL PROPERTIES OF ALLOYS OF ALUMINIUM, MAGNESIUM AND SILICON, COMPRISING SUBJECTING AN ALUMINIUM-MAGNESIUM-SILICON ALLOY TO SOLUTION HEAT TREATMENT AT A TEMPERATURE OF BETWEEN APPROXIMATELY 450* TO 600*C., QUENCHING THE ALLOY TO APPROXIMATELY ROOM TEMPERTURE, REHEATING THE ALLOY TO A TEMPERATURE OF FROM APPROXIMATELY 100 TO 250*C. TO PRELIMINARILY AGE THE ALLOY WITHIN A FEW MINUTES AFTER QUENCHING, AND SUBSEQUENTLY AGAIND HEATING THE ALLOY IN ORDER TO FINALLY AGE THE ALLOY.
