6061 aluminum alloy summary: 6061 aluminum alloy after heat treatment the pre-tension technology production of high quality aluminum alloy products, its strength is not compared with 2 or 7 XXX XXX department system, but its more magnesium, silicon alloy
In essence, heat treatment makes magnesium behave, in vitro and in vivo, more like titanium." Torroni thinks the results auger well for eventual clinical appliions of T-5 magnesium, whose mechanical properties are comparable to titanium, even in mandibular fractures, where stress on bone is particularly high.
Microstructure and mechanical behaviors of AZ91 cast magnesium alloys with melt superheating and thermal rate treatment technique were studied. Alloy grains thicken at 820 C and refine at 870 C when they contains Mn element and the crucible had no coating

The four digit alloy designation also includes a suffix to indie the type of heat treatment, temper, or type of straining process used to impart mechanical properties to the alloy. The two egories of suffix are for alloys that are heat treated to obtain physical properties and alloys that obtain physical properties by stain hardening, aging and tempering.p>
The effect of its heat treatment was also observed. It has been found that it is possible to produce a high-quality Ni-P coating on an AZ91 magnesium alloy which has no visible defects or obvious undesirable interlayers, however the heat treatment of the coating causes its cracking.

A method comprising excimer laser surface treatment of magnesium alloy WE43 for improvement of corrosion resistance is discussed. The WE43 alloy was heat-treated to the -aged conditions. The excimer laser with wavelength was fixed at a duration and frequency of 25 nanosecond and 248 nanometer respectively.
The alloy is Li-rich and a solute nanostructure within a body-centred cubic matrix is achieved by a series of extrusion, heat-treatment and rolling processes. Corrosion resistance from the environment is believed to occur by a uniform lithium carbonate film in which surface coverage is much greater than in traditional hexagonal close-packed Mg-based alloys, explaining the superior corrosion
