Abstract :

In the present study, Al-4 vol .% SiC composites were produced by mechanical alloying and the correspondence of the creep results were obtained from different methods (the advantages of lower time of test). The coefficient between impression and compression creep rate for stresses of 30 and 32.5 MPa and 35 MPa and impression stresses of three times of compression stresses (90, 97 and 111 MPa) were constant (2.5) in different microstructures. This constant coefficient showed that the condition of composite production was similar to the steady state condition of mechanical alloying process and has been proved with composite microstructure. According to the relaxation results, the different nano SiC distribution and the porosities lead to the variations in the steady state relaxation rate and the relaxation rate decrease with time was due to the work hardening mechanism. Also the high amount of coefficient showed that the effect of porosity was more than nano SiC in impression and relaxation rate increase.
