The splints are narrow metal strips arranged longitudinally, pierced for riveting or sewing to the foundation. Splint armor is most commonly found as greaves or vambraces . It first appears in a Scythian grave from the 4th century BC [ 1 ] then in the Swedish Migration Era ; [ 2 ] and again in the 14th century as part of transitional armour ...
In Japan, mail and plate armour is called "karuta", small square or rectangular rawhide or metal plates with the gaps between them filled with mail. [9] The first known use of iron plate mail in Korea was used by the Gaya Confederacy between 42 and 562 AD. A large number of iron and steel artifacts, including iron armor, iron horse armor such ...
Cast aluminium alloys yield cost-effective products due to the low melting point, although they generally have lower tensile strengths than wrought alloys. The most important cast aluminium alloy system is Al–Si, where the high levels of silicon (4–13%) contribute to give good casting characteristics. Aluminium alloys are widely used in ...
Forearm guard. May be solid metal or splints of metal attached to a leather backing. Bracers made of leather were most commonly worn by archers to protect against snapping bowstrings. Developed in antiquity but named in the 14th century. 'Vambrace' may also sometimes refer to parts of armour that together cover the lower and upper arms. Gauntlet
For aluminum castings, sand casting represents about 12% of the total tonnage by weight (surpassed only by die casting at 57%, and semi-permanent and permanent mold at 19%; based on 2006 shipments). The exact process and pattern equipment is always determined by the order quantities and the casting design.
Carvel built or carvel planking is a method of boat building in which hull planks are laid edge to edge and fastened to a robust frame, thereby forming a smooth surface. Traditionally the planks are neither attached to, nor slotted into, each other, having only a caulking sealant between the planks to keep water out.
Although no published standard defines the system, it is produced in a series of conventional sizes which allows for compatibility between manufacturers. There is a variation on T-slot profiles known as V-slot rails where V-slot wheels are slotted into the V-shaped channels of the framing for linear motion in a 3D printer or other CNC machine .
Current aluminum alloys are soft and often require hard, heavy cast iron liners which reduces the benefits of the lightweight aluminum engines. Fracture toughness of the composites is typically dominated by the metal phases; however, it can also be dominated by the ceramic phase or delamination depending on the material system. [ 14 ]
