History of Electrum. This gold-silver alloy has a long history of being used by humans. It was used for different purposes since third millennium BC. However, the variation in the gold and silver contents of this alloy made it difficult to decide the value of each coin.
Malleability is the ability of materials to deform easily under compressive stress. This can be often characterized as materials ability to form thin sheets by hammering or rolling. On the other hand, Ductility is the ability of materials to deform easily under tensile stress.
Apr 25, 2016 Â·. The relation between the hardening parameters and ultimate tensile strength depends upon the hardening behavior of the material. The ultimate tensile strength occurs when the uniaxial strain (in tensile test) equals the hardening exponent (assuming a power hardening law which is valid for carbon steel). So if you know the TS and n of the material you can find out K.
