Mechanical Properties at Elevated Temperatures
In projecting applications of magnesium alloys at elevated temperatures, the tensile and other mechanical properties at the particular service temperatures must be considered. On account of their relatively low melting points, below about 1200oF (650oC), the commercial alloys are necessarily confined to ...

Magnesium alloys usually are heat treated either to improve mechanical properties or as means of conditioning for specific fabricating operations. The type of heat treatment selected depends on alloy composition and form (cast or wrought), and on anticipated service conditions.
Solution heat treatment improves strength and results in ...

The main components of the alloys are magnesium and silicon to form Mg2Si. There is often an iron corrector such as manganese or chromium; occasionally small amounts of copper or zinc to improve the strength without substantial loss of corrosion resistance; boron in conductors to remove titanium ...

Aluminum Bearing Materials
Aluminum alloys with desirable bearing properties are used in a wide variety of applications. Steel-backed and solid aluminum bearings are employed as connecting rod and main bearings in internal combustion engines and industrial compressors. Other aluminum bearing applications are in heavy tooling, such as boring mills, presses, lathes, ...

Titanium has an image of being a rare, hard to get, difficult to work with material. Titanium is an element, atomic number 22 on the periodic table. Titanium is the fourth most abundant metal on our planet. Titanium is most often mined as the ore rutile or ilmenite.
Titanium was not ...

All commercial aluminum alloys that comprise this group contain more zinc than magnesium. There are a few commercial alloys with Zn:Mg < 1, but they have been considered with the aluminum-magnesium alloys because their behavior and structure are much closer to those of aluminum-magnesium alloys than of aluminum-zinc-magnesium.
Table 1 shows ...
