Study of the Artificial Aging
Kinetics of Different AA6013-T4 Heat Treatment Conditions (J.
A study on the effect of hot isostatic pressing (HIP) on the microstructure and tensile properties of A356-T6 cast aluminum alloy cast into a plate and machined to a test bar according to ASTM E8M found the solution treatment was 1,000F (538C) for 5 hours; artificial aging
was 320F (160C) for 4 hours.
The automated heat treating system included a solution furnace with rapid quench transfer capabilities and artificial aging
Since 1996, the chemical/physical department at the laboratories in Ciyitanova Marche has also been conducting in-house artificial aging
There is a known inverse correlation between lipid oxidation and seed longevity during natural and artificial aging
Wilful deception, stylistic mimicry, artificial aging
, factious provenances, false signatures--all of these characterise forgery.
Among their topics are the non-Gaussian diffusion of phosphorus and arsenic in silicon with local density diffusivity model, the artificial aging
behavior of 6063 alloy studied using Vickers hardness and positron annihilation lifetime techniques, the liquid-phase sintering of tungsten heavy alloys, new experimental proof of phase and structure formation in metallic materials eletrodeposited through a liquid state stage, the variable range hopping model in manganese oxides, and dynamics of trililoxane wetting of hydrophobic surfaces.
Models also had to withstand an artificial aging
process involving exposure to high temperatures and humidity.
For BGAs, the artificial aging
process significantly degraded the component substrate, causing warping during assembly, and reduced yield for the most severely aged components.
Laboratory tests prove Memorex Pro Gold Media to be resistant to the effects of rapid, artificial aging
such as ultraviolet light, heat and humidity exposure thanks in part to gold's inert characteristics that prevent oxidation, a common cause of failure for most recordable media during long-term storage.
Behaviour of Artificial Aging
in 6066 Alloy Using Microhardness and Nuclear Techniques
Straightening is done after the heat treat quench cycle and before the artificial aging
process, when castings are still somewhat ductile and can be manipulated easily, although heavy or thick-walled castings may be hard to bring back into accurate dimensions.
