Abstract

There is high demand for brass in industrial applications, the automotive industry, electrical and electronics industry and building industry is increasing; this necessitate the improvement of their mechanical properties by heat treatment process. Material properties largely determines its usage in any engineering application. There are several ways in which the integrity of materials can be tested to determine properties like strength, ductility, hardiness and elasticity tendencies inherent in the materials. This can be determined by subjecting the specimen to different load conditions.One underline method that differentiate heat processes from other is the rate of cooling or medium of cooling. In this research, two samples of MT40N were heated in a hearth forging furnace to austenitic temperature. The samples were heated for about 5 minutes simultaneously. The samples A and B were quenched in chilled water and in oil with equal volume being 500cl in each case. After cooling, the specimens were tested to determine their resistance to twisting or torsional load. A bench device SM1001 VersatileDevice AcquisitionSystem (VDAS) was used to measure its torsional properties. Specimen A was inserted and twisting force was applied until it reaches a break point. Specimen B was also was tested with same apparatus and twisting force is applied. The result shows that sample A was hardened and no appreciable necking was evidence before it snap off at peak torque of 9.5 Nm and maximum twist angle of 15.55 rad. While in sample B it shows substantial necking and withstand 32Nm torque and 210rad for angle of twist before it fractures, which depicts a ductile material. This findings suggests that heating and cooling, particularly in different medium has altered the behaviour of the materials. These specific findings can be applied by engineers and materials users as they respond to competitiveness demand in respect of quality assurance in materials usage.
