摘要: There is a significant body of literature wherein linear approximation Escaig's model used to justify the large experimentally measured activation-volumes for cross-slip in face-centered-cubic copper. Here, by examining error between and original theory, we show that this explanation not satisfactory. The calculated value activation volume copper, using equations, yields ∼60b 3 (b = Burgers vector) while 200b 3, latter result fortuitously matching experimental values.
