Aluminium alloy 7050 is an aerospace grade of aluminium combining high strength stress corrosion cracking resistance and toughness. It is particularly suited for heavy plate applications (3 to 6 thick) due to it's lower quench sensitivity and retention of strength in thicker sections.
Get PriceThe article established a modelling that predicted and measured the quenching and pre-stretching stress in 7050 aluminum alloy thick plate in order to make the alloy suitable enough for ...
Get PriceThe 7050 aluminum alloy of composition shown in Table 1 was used in the experiments.Quenching samples of 40 mm in diameter and 150 mm in height were machined in rolling direction from hot rolled 7050 plates.After solution treated at 470 °C for 30 min the samples were quickly transferred to the end quenching rig (less than 5 s) as shown in Fig. 1.

Get Pricethe T-section 7050 aluminum alloy forging and residual stresses due to temperature changes using MSC.Marc. It was assumed that there were no stresses in the forging at the beginning of quenching since the forging was heated and held at 475°C which is above the recrystallization temper-ature of 7050 aluminum alloys.
Get PriceOpen die forged 7050 aluminum alloy has residual stresses that can be measured by the hole-drilling method following standard ASTM E837-01. Weber Metals (Paramount CA) assumes that the stress is uniform throughout the thickness of an open die forged plate. Four different stress relieved 7050 aluminum samples were tested to confirm if the measurements by the hole-drilling method at the surface ...

Get PriceResidual stresses were determined through the thickness of quenched and quenched followed by cold compression 7050 aluminum alloy T-section forgings using the contour method and neutron diffraction. 7050 T-section forgings are used for the manufacture of the connecting joints of wing and fuselage. Inevitably high residual stresses are introduced during the quenching process of 7050 T-section ...

Get PriceDistortion frequently occurs during machining of age-hardening aluminum alloys due to residual stresses that were introduced during the quenching step in the heat treatment process. Options for reducing these residual stresses have been investigated in two extensively used aluminum alloys: 7075 and 6061.
