Mechanical Testing of Metals

The National Metals Technology Centre (NAMTEC)

Course Description

Metals are the most versatile of engineering materials providing a diverse range of properties for applications such as vessels used for the storage of liquid Helium at -269?C to Tungsten filaments in electric lights working at 3,000?C . In addition strengths differ by more than a factor of 100. For any given application a metal must exhibit a range of generally conflicting properties. It is necessary therefore, to be able to measure mechanical properties in order to ensure that metals supplied are suitable for the intended application. For this purpose a large number of mechanical tests have been developed. Introduction to why materials are tested Tensile testing,what properties are measured, how and why ? Tensile testing - what machines are used, control issues Demonstration of tensile testing in Corus RD&T Laboratories Impact testing - what is measured, how and why? Impact testing, what machines are used, temperature control Demonstration of Charpy and Izod Impact testing Hardness testing, what , how and why ? How hardness testing is carried out, considerations, conversions Demonstation of hardness testing Uncertainty of measurement 08.45-09.00hrs Registration. 17.00hrs Finish.
