Osmium (from Ancient Greek ὀσμή (osmḗ) ' smell ') is a chemical element; it has symbol Os and atomic number 76. It is a hard, brittle, bluish-white transition metal in the platinum group that is found as a trace element in alloys, mostly in platinum ores. Osmium is the densest naturally occurring element.

Alumina Partners of Jamaica, also known as Alpart, is a company that owns and operates a bauxite refinery in Nain, Jamaica. [1] Alpart was founded in 1969 as a joint venture by Kaiser Aluminum, Reynolds Aluminum, and Anaconda. [2] Alpart exports 1.65 million tonnes of alumina overseas per year, and earned gross revenues of US$1.3 billion in ...
The failure of a material is usually classified into brittle failure or ductile failure . Depending on the conditions (such as temperature, state of stress, loading rate) most materials can fail in a brittle or ductile manner or both. However, for most practical situations, a material may be classified as either brittle or ductile.

The chemical elements can be broadly divided into metals, metalloids, and nonmetals according to their shared physical and chemical properties.All elemental metals have a shiny appearance (at least when freshly polished); are good conductors of heat and electricity; form alloys with other metallic elements; and have at least one basic oxide.

The ductile failure model of Lynch [17] and Popovich [18] predicted that adsorption of the liquid metal leads to the weakening of atomic bonds and nucleation of dislocations, which move under stress, pile up and work harden the solid. Also, dissolution helps in the nucleation of voids which grow under stress and cause ductile failure.
