In a demonstration, a metal sphere dropped on amorphous steel bounced significantly longer than the same metal sphere dropped on crystalline steel. [ 4 ] The lack of grain boundaries in a metallic glass eliminates grain-boundary corrosion—a common problem in high-strength alloys produced by precipitation hardening and sensitized stainless steels.
List of bicycle parts by alphabetic order: Axle : as in the generic definition, a rod that serves to attach a wheel to a bicycle and provides support for bearings on which the wheel rotates. Also sometimes used to describe suspension components, for example a swing arm pivot axle
Lead-Bismuth Eutectic or LBE is a eutectic alloy of lead (44.5 at%) and bismuth (55.5 at%) used as a coolant in some nuclear reactors, and is a proposed coolant for the lead-cooled fast reactor, part of the Generation IV reactor initiative.
Double wishbone suspension (front) on a Saab Quantum IV. The double-wishbone suspension can also be referred to as "double A-arms", though the arms themselves can be A-shaped or L-shaped. A single wishbone or A-arm can also be used in various other suspension types, such as variations of the MacPherson strut.
Pull-rod suspension and push-rod suspension refer to a specialised type of automotive suspension system which is largely based on a double-wishbone system, incorporating elements of the commonly used MacPherson strut. [1] In cars, suspension refers to the system by which the vehicle maintains contact between all of its wheels and the ground.
Liquid Metal may refer to: A liquid metal, which has a relatively low melting point, such as mercury, tin or lead; Any metal in a liquid state; Mercury, the only metal to be liquid at room temperature; Liquid metallic hydrogen; Liquidmetal, a type of metallic glass; Liquid Metal (Sirius XM), a radio channel
The tube is positioned in liquid metal. By creating a vacuum inside the tube, the metal with the suspended inclusions to be detected is forced through the small orifice. Two electrodes are necessary: one inside the tube and the other outside. Both electrodes are immersed in the liquid metal. A constant electric current is applied between the ...
Galinstan is a brand name for an alloy composed of gallium, indium, and tin which melts at −19 °C (−2 °F) and is thus liquid at room temperature. [4] [5] In scientific literature, galinstan is also used to denote the eutectic alloy of gallium, indium, and tin, which melts at around +11 °C (52 °F). [5]
