WebIt is represented as a bold letter “b.” Jan Burgers, a Dutch Physicist, coined this term. The significance of the Burgers vector can only be understood once we compare a dislocation-free crystal with that of a crystal having dislocations. Thereby, the magnitude and direction of the Burgers vector can be visualized clearly in Figure 1.44. WebThe Burgers vector has a constant magnitude and direction for a given dislocation. The line of the dislocation is characterized by a line vector, t, that points along the local direction of the defect. An edge dislocation has its Burgers vector normal to its line vector. A screw dislocation has its Burgers vector parallel to its line vector. prototype chicahttp://micro.stanford.edu/mediawiki/images/d/d5/Burger_vec_v02.pdf prototype chile
