Mithril is a fictional metal found in J. R. R. Tolkien's Middle-earth writings. It is described as resembling silver, but being stronger and lighter than steel.It was used to make armour, such as the helmets of the citadel guard of Minas Tirith, and ithildin alloy, used to decorate gateways with writing visible only by starlight or moonlight.
The US Army in the summer of 1974 faced the choice between the German system and their own Burlington, a decision made more difficult because Burlington offered, relative to steel armour, no weight advantage against KE-penetrators: [41] the total armour system would have a RHA equivalence against them of about 350 mm (compared to about 700 mm ...
A Chinese publication lists 30MnCrNiMo "685" steel as the material used in Chinese rolled armor plates, with a Brinell Hardness of HBW 444-514 (thin) / 429-495 (thick). According to the same publication, older vehicles use a 22SiMn2TiB "616" steel with a hardness of HBS ≤ 219.
It contained a few short skirts on the side of the vehicle which are opened in open terrain at an angle of between 30–45°, increasing the space between the armour and the plate. It was effective (mass-to-efficiency ratio), but easily detached from the vehicle so it did not spread widely.
In diamonds, the cut is the primary determinant of value, followed by clarity and color. An ideally cut diamond will sparkle, to break down light into its constituent rainbow colors (dispersion), chop it up into bright little pieces (scintillation), and deliver it to the eye (brilliance).
In contemporary sources it was sometimes also referred to as an 'armet', though modern scholarship draws a clear distinction between the two types. [1] While outwardly very similar to the armet, the close helmet had an entirely different method of opening. Like the armet, the close helmet followed the contours of the head and neck closely, and ...
Advanced Modular Armor Protection (AMAP) is modular composite armour concept, developed by the German company IBD Deisenroth Engineering, since 2019 part of Rheinmetall Protection Systems. According to IBD AMAP is a 4th generation composite armour, making use of nano-ceramics and modern steel alloy technologies. [ 1 ]
It was usually a single piece of plate armour protecting the chin and throat and filling the gap between the helmet and breastplate. [1] The bevor could also extend over the knight’s left shoulder doubling the thickness of the armour. [3] The bevor was originally worn in conjunction with a type of helmet known as a sallet. [4]
