Suppose that all the dislocations in 2000 mm3 of crystal were somehow removed and linked end to end. Given 1 m =0.0006214 mile, how far (in miles) would this chain extend for dislocation densities of

(a) 103 mm-2 (undeformed metal)?

(b) 1010 mm-2 (cold-worked metal)?

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

The thermal expansion or contraction of a given metal is a function of the f a)-density b)-initial temperature c)- temperature difference d)- linear coefficient of thermal expansion e)- final temperature f)- original length

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
