The influences of Cr on dispersed phase and properties Al-Zn-Mg-Cu-Zr alloys were investigated by mechanical testing, slow strain rate stress corrosion, intergranular combined with optical microscope, scanning electronic transmission microscopy (OM, SEM, TEM). Research shows that: the increase element Cr, recrystallization grain growth had been inhibited, strength, toughness corrosion resistance alloy increased first then decreased; when added 0.1 wt% element, are best. main reasons that as...
By means of TEM, hardness, conductivity, tensile strength test, fracture toughness polarization curve and EIS, the Al-Zn-Mg-Cu alloys treated by a new multi-stage aging system, i.e. pre-aging, over-aging re-aging (120°C/24h + 160°C/8h 120°C/24h), were characterized. It is found that compared with T76 160°C/8h), treatment can improve strength, toughness, hardness conductivity at same time. This mainly due to process super high aluminum alloys. Compared two-stage over process, formation...
The effect of salt loading on chloride-induced stress corrosion cracking in 304L was studied at atmospheric pressure. Stress relieved samples were uniaxially pre-strained to 5% and loaded with nine levels MgCl2 from 2.3 x 10-4 4.2 10-2 g.cm-2. Samples subject 60 MPa stress, 90°C 70% relative humidity, for 480 hours. A direct correlation between the density observed 7.6 2.6 g.cm-2 . Crack propagation rates constant loadings 3.2 1-2 µm.hr-1.
