for the strong crystal orientation dependence of friction and wear behaviors of the single crystal zirconium at the nanoscale. Moreover, the effects of tangential dislocation motion on the friction force and wear amount of single crystal zirconium are more significant than those of normal stacking fault. Key words: single crystalline zirconium; molecular dynamics; nanoscale; friction and wear......
