Aluminium alloys have been widely used in aeronautical engineering due to the advantages of high strength and easy processing. Low temperature is an inevitable environmental factor in using of aluminium alloys

and the cryogenic fatigue of aeronautic aluminium alloys has been greatly concerned by the engineering and academics overseas and domestically. The experiment researches on cryogenic fatigue of aeronautic aluminium alloys in recent years were generally reviewed here

meanwhile

the cryogenic fatigue failure mechanisms were analyzed. After that

the characterization model and life evaluation methodology on cryogenic fatigue of aeronautic aluminium alloys were summarized

and further research problems in experiment

failure mechanism

characterization model and life prediction were pointed out

which provides a technical support for engineering design and application of aeronautic aluminium alloys.
