11 shows that the Zn-rich area beneath the oxide follows the same structure as the Al matrix rather than forming a new Al-Zn phase. Fig. 4: STEM analysis of a peak-aged Al-Zn-Mg-Cu alloy after exposure to 0.1 M KCl for 3 h. a Low magnification HAADF image showing the ...

If you bend a pair of shape-memory eyeglasses, the stress you apply makes the titanium alloy from which they're made flip into an entirely different crystalline structure; let go and the crystalline structure reverts back again, so the glasses spring back to their original shape....
who left the Univ. of Penna. In 1946, no longer had access to the documents which might have helped to show “who did what, when.â€Â But after many years, litigation has unearthed some of those documents, and historians can read what was once classified. But,...
To achieve its maximum hardness a steel needs to form full martensite. At high temperature the steel is in the “austenite” phase, and when quenched rapidly it transforms to martensite. You can read about the formation of austenite inthis article, and about martensite formation and why it is...
Photo 2. The brushes in a "can" motor are held in place by alloy leaf springs that also serve to carry current. The commutator has been simulated with a piece of dowel with some markings on it to better show how it mates with the brushes. ...
Due to the high share of industry in total electricity consumption, industrial demand-side management can make a relevant contribution to the stability of power systems. At the same time, companies get the opportunity to reduce their electricity procurem
