In view of developing a physics-based constitutive material model for AA7075-T651, the mechanical behavior and microstructure evolution has been studied through compression tests using Gleeble thermo-mechanical simulator. The were performed at wide range temperatures (room temperature (RT), 100, 200, 300, 400 500 °C) with two constant strain rates (0.01 1 s-1). true stress-strain curves depicte...

Hydrogen embrittlement affected by three types of plating (low-P and high-P electroless Ni-P electrolytic Zn-platin) was investigated means slow-strain-rate three-point bending test on aluminum alloys (2017-T3, 6061-T6 7075-T651). generated the zinc absorbed alloy substrates, trap sites in substrates for hydrogen differed between plating. able to be evaluated tests plated alloys. Zinc did not c...

This work proposes a methodology to compute fretting fatigue crack initiation and total life by iterative models calibrated with stress–strain-life curves. One of the main novelty such is assumption that length determined size critical distance. To separate propagation lives, numerical approach finite elements used. The incorporates not only multiaxial non-proportional characteristic stress fie...
