The Jominy End Quench Test Report Uitm
Before removing the sample from the furnace prepare the water for the quenching the end of the.
The jominy end quench test report uitm. Place the jominy sample upright in a 1000 c furnace for 30 minutes to create a phase known as austenite completely through the sample. Aimthe aim of the jominy end quench test was to identify and confirm the achievement correct hardenability in accordance with what is already stated or in the record as the current hardenability data for steel. The setup of the jominy end quench test the procedure for the jominy end quench test is as follows. Me3302 laboratory report jominy hardenability test group 18 name student id chan ka chun 10194287d ho kwok yan 10140391d liu chang 09837260d tao wai tin 10193661d ye han 09807520d 3 introduction 1 1 objective the objective of this laboratory experiment is to perform jominy tests for 760 s50c carbon steel by using water at 24 c to determine the hardenability of the 760 s50c carbon steel.
Introduction the hardenability of a steel is defined as that property which determines the depth and distribution of hardness induced by quenching ftom the austenitic condition. Information about the hardenability of steels is necessary to be able to select the appropriate combination of alloy steel and heat treatment to manufacture components of different size to minimize thermal stresses and. Data from the jominy end quench test can be used to determine whether a particular steel can be sufficiently hardened in different quenching media for different section diameters. It also discusses how the information obtained from the jominy test can be used to understand.
For this test a slightly oversized bar of steel is normalisad at about 66 c 150 f above ac 3 and then machined to the final dimensions of 4 102 mm long and 1 25 4 mm diameter fig. The jominy end quench test is used to measure the hardenability of a steel which is a measure of the capacity of the steel to harden in depth under a given set of conditions. Jominy end quench test is quite simple and easy test and is thus almost universally employed for the determination of hardenability. Jominy hardenability test objective to study hardness as a function of quench rate and investigate the hardenability of steels.
Purposethe purpose of the jominy end quench test was to realize the exploration of the relationship that exists between the composition and the hardenability of various forms of steel. For example the cooling rate at a distance of 10 mm 0 390 in from the quenched end is equivalent to the cooling rate at the center of an oil quenched 28 mm 1 1 in diameter bar. The jominy end quench test is used to measure the hardenability of a steel which is a measure of the capacity of the steel to harden in depth under a given set of conditions. Currently the jominy end quench test.
The jominy end quench test is used to measure the hardenability of a steel.
