Numerical Simulation and Experimental Study on Cyclic Extrusion Compression for Particle Reinforced Al Composite
The cyclic extrusion compression(CEC)was simulated numerically by Deform software for particle reinforced aluminum composites.The orthogonal simulation tests were evaluated by the application of the entropy weight and technique for order preference by similarity to ideal solution.The preferred process was used in CEC experiment.The results show that the titanium aluminum intermetallic compound reinforced particles with the core and shell structure are not broken up nor separated from the matrix during CEC.The coarse Ti grains formed in hot-pressing sintering TiAl3 shell are refined effectively after CEC.
