| Abstract | ||
| The hot deformation behaviour of 606 1 A1 alloy/SiCp composite are investigated by means of compression tests under constant strain rates of 0.1, 1 .O, and 5.0 s'l and at temperatures ranging from 100 to 500 OC. 'l'lie high reductions, varying from 10 to 60 % with intervals of 10% are set to investigate the hot workability of these materials. A specially designed furnace has been fabricated for this purpose. The flow stress data are analyzed in terms of strain rate and temperature .. .. sensitiv~tles. 'The experimental results show that the flow stress decreases as the temperature increases. The strain rate affects the flow stress slightly. The forming limit diagram of 6061A1 alloy1SiCp composite was determined. It was shown that the forming limits increases with increasing temperature and the variation in strain rate has a significant effect on hot workability. | ||
