A perfect dislocation in Fe (bcc lattice) has its Burgers vector 5 = all 1] , where a is the lattice constant; its dislocation line direction is f = [1 2 2]. 1) Calculate the edge component be and screw component 55 of its Burgers vector 5. 2) What is its slip plane? Write it down using the correct Miller index (hkl). 3) If there is another dislocation with its Burgers vector 52 = %[1 1 1], can I) and 52 be on the same slip plane? What is this slip plane? Write it down using the correct Miller index (hkl). 4) Can these two dislocations above (5 and 52) combine with each other into a new dislocation as E + 52 > 53? Why? Will 53 tend to make slip easier or more difcult? Why
