What is the microstructure of metals? - Quora

When most molten metals solidify normally as the temperature falls below the melting point,they form crystalline structures,along with inclusion of other metallic or nonmetallic inclusions ( included within the crystal structure).The crystals fUS20140236284A1 - Bioerodible Magnesium Alloy A bioerodible endoprosthesis includes a bioerodible magnesium alloy.The bioerodible magnesium alloy has a microstructure including equiaxed Mg-rich solid solution-phase grains having an average grain diameter of less than or equal to 5 microns and second-phase precipitates in grain boundaries between the equiaxed Mg-rich solid solution-phase grains.Some results are removed in response to a notice of local law requirement.For more information,please see here.Previous123456NextMetallography and Microstructures of Cast IronMicrostructures of Cast Iron Janina M.Radzikowska,The Foundry Research Institute,Krako MICROSTRUCTURE OF ALLOYS#180;w,Poland CAST IRON is an iron-carbon cast alloy with other elements that is made by remelting pig iron,scrap,and other additions.For differentia-tion from steel and cast steel,cast iron is dened as a cast alloy with a carbon content (min2.03%)

What is a microstructure? Metals are crystalline when in the solid form.The crystal structure of a solid metal refers to the internal structure or arrangement of the atoms in an ordered,repeating,three dimensional pattern.Normal metallic objects are polycrystalline,which means they consist of an aggregate of many very small crystals.
