蚀性能是7050一T73铆钉必须具备的性能, 而淬火转移时间对晶间腐蚀和力学性能影响 较大。Al—Zn—Mg—Cu系铝合金,为使制品 具有最大抗腐蚀性能,需快速淬火,当淬火 速度较慢时,则合金对晶间腐蚀格外敏感, 在腐蚀条件下,合金力学性能显著降低。 目前很少有不同淬火转移时间对晶间 ...

A new fracture area method for predicting the growth of a newly coalesced crack in AA7050-T7451 aluminium alloyMultiple cracks, Short cracks, Fatigue crack growth, Experimental data, Life predictionA period of crack growth "retardation" after coalescence of a pair of cracks, propagating under ...
Specimens obtained after 6 and 12 days were subjected to routine processing for electron microscopy as well as fixation using the Ka-pyroantimonate technique. The electron micrographs revealed that initial osteoblastic differentiation and formation of collagenous matrix were followed by Ca accumulation in ...
New retrogression and reaging process for 7050 aluminum alloys, having the yield strength of 600MPa and stress corrosion resistance equal to 7050-T74, has been developed. New Process is combined higher aging and reaging temperature and lower reversion temperature. These treatments brought out wider...
