Ballistic Evaluation of Magnesium Alloy WE43C
The ballistic performance of magnesium Mg alloy WE43C was assessed against armor-piercing and fragment-simulating projectiles. V50 ballistic protection limits were determined for various thicknesses of material ranging from 0.25 to 2.94 inches. These results were used to determine new ballistic acceptance tables in MIL-DTL-32333A for WE43C, which was added as a new class of applique armor
Metallography and Microstructure of Aluminum and Alloys
Apr 14, 2012· Compared to many other metals and alloys and many other materials, such as carbides, ceramics and sintered carbides, aluminum and its alloys are low in strength and hardness. Aluminum is a soft, silvery metal with a face-centered cubic crystal structure, a hallmark of ductile metals. Its softness makes it somewhat difficult to prepare but the alloy is not sensitive to problems that plague

How Is Magnesium Metal Produced? - ThoughtCo
Nov 24, 2019· In this process, closed-end, nickel-chromium-steel alloy retorts are filled with a mixture of calcined dolomite ore and ferrosilicon, which are heated until magnesium crowns form. Each cycle takes about 11 hours, requires manually filling and emptying of the vacuum tubes, and uses about 11 tons of raw materials for every one ton of magnesium
Aluminium alloy - Wikipedia
Aluminium alloys (or aluminum alloys; see spelling differences) are alloys in which aluminium (Al) is the predominant metal. The typical alloying elements are copper, magnesium, manganese, silicon, tin and zinc.There are two principal classifiions, namely casting alloys and wrought alloys, both of which are further subdivided into the egories heat-treatable and non-heat-treatable.

How to Avoid Cracking in Aluminum Alloys - AlcoTec
This alloy group welds easily with the high magnesium filler alloys such as 5356, which ensures the weld contains sufficient magnesium to prevent cracking. The recommendation of silicon-based filler alloys, such as 4043, for these alloys is not desirable because the excess Si introduced by the filler alloy can result in the formation of
Conversion of Mg‐Li Bimetallic Alloys to Magnesium
According to the Li‐Mg phase diagram, magnesium and lithium phases (α‐Mg, β‐Li) coexist in a Mg 0.5 Li 0.5 alloy. Because each grain exhibited the same contrast in SEM and the same O content in EDS mapping, we conclude that each grain exhibits the same Mg and Li fractions and that β‐Li phase is primarily present in the grain boundary
