In metals, the crystal topology drives many mechanical and electrical properties. The arrangement of various crystals and the geometry of the boundary between crystals, grain structure, is another important material characteristic on the microscopic level. Grain size and structure are significant drivers ...
At what point the material fails is important to know when processing metals. Temperature has an effect on steel flow stress, which typically decreases when a material becomes softer as it becomes hotter. Stress also increases in a metal that changes phases when heated, as well as if a ...

Where is ore found? Ore is adeposit in Earth's crustof one or more valuable minerals. The most valuable ore deposits contain metals crucial to industry and trade, like copper, gold, and iron. Copper ore is mined for a variety of industrial uses. ...
Metals with more plasticity are easier to form. Grain direction is important in high strength materials, such as tempered metals and stainless steel. If a bend goes along the grain of a high strength, it can be prone to cracking. Bend height Bend relief Bend Distortion/Bulge: The bulging ...
• Annealing removes residual stresses. Residual stresses can create cracks and other mechanical complications, and it is often best to eliminate them whenever possible. What Metals Can Be Annealed? To perform an annealing process, a material that can be altered by heat treatment must be used. ...
Available in four different versions and two different metals, 18k white gold or 18k red gold, the 40mm case plays host to what can only be described as a horological spectacle. At 12 o’clock there is an off-centre dial, replete with Roman numerals for the hours and Breguet hands. ...
