| Summary |
"The purpose of the thesis was to evaluate the quenching speed of different quenching media by studying their behaviour in relation to hardenabilities of steels, using the standard A.S.T.M. End-quench Test. At the outset an understanding of the term "Hardenability", so extensively used in industrial heat-treatment, is necessary, The property of a steel, of hardening on quenching to various depths beneath the surface is referred to as the 'Hardenability". It may simply be called the "susceptibility to hardening". Hardenability should be distinguished from the "Hardening capacity", which represents the magnitude of the hardness achieved. The chief factors which affect the inherent hardenability of a steel are: 1. Amount of carbon in the steel. 2. Nature and amount of alloying element. 3. Austenitic grain size. 4. Method of manufacture. Besides these, there are other external factors which should be considered in performing any hardenability test"--Introduction, leaves 1-2. |
