Aluminum Strain Hardening Exponent 1

From ASM Handbook, Volume 8, Mechanical Testing and Evaluation, under Component testing,,,,,

7075 T6 monotonic load, n=0.113
6061 data for T651 only, monotonic load, n=0.042
2014 T6 not reported

Metengr,

Thank you so very much for the quick response and location of the data.

Aluminum alloys have a FCC crystal structure and low stacking fault energy, which means that dislocation cross slip is extensive, and therefore they do not significantly strain harden. 2014-T6 will be in the same range as the other two alloys, probably closer to 7075.

I found the reference below and it looks like the strain hardening exponent reported for 2014-T6 is 0.064 +/- .003
