F I G U R E 7 Optical microscopy images of the cross ‐ section of the AA6005 and model alloys after 10 – 120 h of immersion in the accelerated intergranular corrosion test
The effects of quench rate after solution heat treatment in combination with 1% pre-deformation on precipitation hardening in three Al-Mg-Si alloys have been investigated by
We have measured the hardness evolution during artificial aging of a base Al–Mg–Si alloy with 0.0019, 0.0060 and 0.0727 at.% Ca additions and studied the materials using TEM and
We have shed light on some important findings regarding the muon trapping in the materials and its interpretation in terms of (sub-)nanometer- sized defect content. In particular,
The correction factors were implemented into a KWN model framework and tested by predicting the precipitation kinetics of needle-shaped precipitates in Al-Mg-Si
1) First-principles calculations were initiated to investigate the effects of solute Mg and vacancy on the generalized planar fault energy (GPFE) of Al. 2) Both solute
In the low temperature region below 120 K, muons appeared to be trapped in a shallow potential yielded by dissolved Mg atoms, and thus little effect of heat treatment of the samples
The present work contains the first general investigation and application of ab initio molecular dynamics simulations in a strong uniform magnetic field, accounting both for the
