FOUR-STEP THERMAL AGING METHOD FOR IMPROVING ENVIRONMENTALLY ASSISTED CRACKING RESISTANCE OF 7XXX SERIES ALUMINIUM ALLOYS

FOUR-STEP THERMAL AGING METHOD FOR IMPROVING ENVIRONMENTALLY ASSISTED CRACKING RESISTANCE OF 7XXX SERIES ALUMINIUM ALLOYS

Four-step thermal aging method for improving environmentally assisted cracking resistance of 7xxx series aluminium alloys. The thermal aging is carried out by treating the alloys at a temperature of 120 to 130 oC for 0.3 to 0.5 h, water quenching the alloys to a temperature of 25 to 27 oC and furthe...

description Four-step thermal aging method for improving environmentally assisted cracking resistance of 7xxx series aluminium alloys. The thermal aging is carried out by treating the alloys at a temperature of 120 to 130 oC for 0.3 to 0.5 h, water quenching the alloys to a temperature of 25 to 27 oC and further treating the alloys at a temperature of 80 to 95 oC for 100 to 120 h and at a temperature of 120 to 130 oC for 20 to 24 h and at a temperature of 155 to 160 oC for 1 to 5 h and air cooling the alloys to room temperature, sequentially.
