Dislocations are defects in the crystal structure of important engineering materials, such as metals, ceramics and semi-conductors, that strongly influence the properties of these materials. Research on dislocations was intense when the first edition of this classic work was published in the 1960s. By incorporating later developments in subsequent editions whilst retaining a concise, accessible style, Introduction to Dislocations has become established as a key resource for students, graduates and researchers. No other book on the topic is as credible and, with this new edition, as up-to-dat.
