Summary

THE TENSILE PROPERTIES AND FRACTURE BEHAVIOURS OF ALUMINIUM-LITHIUM-COPPER-ZIRCONIUM-IRON-SILICON ALLOY AT DIFFERENT AGING CONDITIONS HAVE BEEN CONDUCTED OVER THE TEMPERATURE RANGE 295-77 K. THE RESULTS SHOW THAT THE TEMPERATURE DEPENDENCE OF THE TENSILE PROPERTIES IS CLOSELY RELATED TO THE HEAT TREATMENT CONDITION. INTERGRANULAR DELAMINATION WAS NOT OBSERVED ON THE CRACKING SURFACE OF SPECIMENS TESTED AT CRYOGENIC TEMPERATURES. HOWEVER, THE ALLOY SHOWED MORE OBVIOUS INTERGRANULAR FRACTURE SURFACE AT CRYOGENIC TEMPERATURES THAN THAT OF AMBIENT TEMPERATURE.
