چکیده انگلیسی
The forming abilities of monatomic chains (MC) of several fcc and bcc metals stretched in three principal crystallographic orientations of [1 1 1], [1 0 0] and [1 1 0] are analyzed in terms of a ratio between Peierls stress of a bulk crystal with dislocations (Ïp) and theoretical shear stress of a monatomic chain (Ïm). It is found that the structure and orientation dependent Ïm/Ïp values are proportional to the forming abilities of MC while Ïm/Ïp is a function of Possion's ratio ν. The above considerations are in agreement with known experimental and simulation results of Au. In addition, Nb as a candidate for MC formation is suggested.
