摘要：

The mechanical behavior of bulk and dense nanostructured copper was investigated. The copper powders with grain size of 60 nm were prepared by powder metallurgy technique and metal extrusion. The metal exhibited high compressive performance with a Hall-Petch yield stress. However, high plastic flow stress and nonconventional plastic strain behavior were also exhibited.
