Alloys are made by melting and mixing the base metal and additional elements (metals and/or non-metals) and allowing them to cool. Two types of alloys exist: substitutional alloys and interstitial alloys. In substitutional alloys, like brass and bronze, the atoms of the alloying elements are similar in size. The atoms of the alloying elements ...

Updated on August 16, 2019. An alloy is a substance made by melting two or more elements together, at least one of them metal. An alloy crystallizes upon cooling into a solid solution, mixture, or intermetallic compound. The components of alloys cannot be separated using a physical means. An alloy is homogeneous and retains the properties of a ...

3.3 Chemical Elements in Steel and Their Effect on Steel Properties. The chemical elements in steel can be gaseous elements (nitrogen, oxygen, hydrogen) or solid elements (non-metals, semi-metals, metals). These elements in turn represent either alloying elements (steel modifiers), accompanying elements or "steel-damaging" elements.
