Dynamic Compression and Tensile Properties of Al Alloys LC4 and LY12CZ at High Strain Rate

Gao Yuhua(Anhui Institute of Technology)  
The al--alloys of LC4 and LY12CZ have ho investigated experimentally under quasi --static and dynamic loading of tensile and compression. The strain rate range is from 10-4tO 1031/s. It is showed that LC4 and LY12CZ arc rate--independent materials, and this insensitivity can be cxplained with the analysis of the theory rate--dependent dislocation. It is also showed that the compressed stress --strain curve is higher than that of tensile, this pheonminum is explained from the view of mcso--scale damage.
