The local structural arrangement of the Cu amorphous was investigated during uniaxial tensile strain and compressive strain using molecular dynamics simulation, respectively. The amorphous of pure Cu system was get through high cooling rate in simulated situation. The amorphous phase of the system did not change in the tension process, whereas in the compression process the amorphous phase transform to bcc crystal structure. The tensile deformation promoted the expansion of the shear transition zones, whereas there is no similar result was observed in the compressive deformation process.
