摘要：The ferrous metals are iron base metals which include all varieties of iron and steel. Most commonengineering materials are ferrous materials which are alloys of iron. Iron is the name given to pure ferrite Fe. The fusedmixtures of this ferrite with varying amount of carbon yields steel and cast iron upon processing. Iron most widely usedof all metals as base metal in steel and cast iron.The tribological and mechanical properties of these ferrous based materials can be controlled or modified byvarious means either varying the alloying elements or by heat treatment process.The properties of these ferrous based materials steel and/or cast iron can also be controlled by varyingsolidification rate by employing different methods. Solidification is a phase transformation process in which liquid istransformed into solid phase upon cooling by liberating the super heat and latent heat of fusion. The properties can alsobe controlled by controlling the microstructure obtained after solidification of liquid metal.Microstructures play a key role in assessing the properties of engineering materials and alloys. They are theimportant link between materials processing and materials behavior. Microstructure control is therefore essential forany processing activity. One of the most important processing routes for many materials, especially metals and alloys issolidification. Steel is an alloy of iron with definite percentage of Carbon ranging from 0.15% - 2.08 %. These plainCarbon steels are classified on the basis of their Carbon content, as their major alloying element is Carbon, steel withlow Carbon content has the same properties as iron i.e. soft but easily formed. As the Carbon content rises, the metalbecomes harder and stronger by compromising ductility.Although the number of steel specifications runs into thousands, plain carbon steel accounts for more than90% of the total steel output. The reason to focus on plain carbon steel group material is that, it is a tough, ductile andcheap material with reasonable casting, working and machining properties and also heat treatable to many properties.An attempt has been made to review various literatures from many researchers related to varying the cooling rate of aliquid metal during solidification and effort to study the different heat treatment processes of steel group materialswhich are responsible for modifying and improving the tribological and other mechanical properties by phasetransformations.
