PPT-Heat Treatment The amount of carbon present in plain carbon steel has a pronounced effect

properties Heat treatment is a method used to alter the physical and sometimes chemical properties of a material The most common application is metallurgical It involves the use of heating or chilling normally to extreme temperatures to achieve a desired result such as .

What and Why Heat Treat?. HEAT TREATMENT is THERMAL PROCESSING to OPTIMISE MECHANICAL PROPERTIES.. Heat Treatment. Heating a metal or alloy to various definite temperatures, holding these for various time durations and cooling at various rates. . Combination of controlled heating and cooling determine not only the nature and distribution of micro-constituents (which determine the properties of a metal or alloy), but also the grain size. . physical, chemical and environmental. properties.. In essence, steel is composed of iron and carbon, although it is the amount of carbon, as well as the level of impurities and additional alloying elements that determines the properties of each steel . Radiodating. A method of determining the age of materials.. Radio-dating works by looking for some radioactive isotope present in a certain material.. All radioactive elements decay at a known rate, the half life.. Richard Peasland. Getting started. You’ll need a notepad on which to make notes as you go along, or you could make notes, paste images, etc. on your device..
