Abstract |
|
The report deals with the comparative study based on the Age Hardening behaviour of Al-3.9%Cu & Al-5%Cu. All samples were solutionized, quenched in water & aged in Muffle Furnace. Hardness test is conducted on all the samples after ageing by Vicker’s Hardness tester. Microstructure of the samples indicates that Cu precipitates form circular structure. Segregation of Cu rich phase (CuAl2) has been found in the vicinity of particle matrix interface. Results after aging shows that the hardness of age hardenable Al-Cu alloy depend on the rate on which alloy is cooled after solution heat treatment. The peak hardness is found to be 128.75 HV1 when the sample is solutionized at 490◦c and aged naturally at room temperature. A maximum of different heat treatment cycles are taken and different results are observed which are discussed in the further report. |
