What Is The Maximum Size Of Copper Ore

We used molecular dynamics simulations with system sizes up to 100 million atoms to simulate plastic deformation of nanocrystalline copper By varying the grain size between 5 and 50 nanometers we show that the flow stress and thus the strength exhibit a maximum at a grain size of 10 to 15 nanometers This maximum is because of a shift in the microscopic deformation mechanism from dislocation
