The introduction of dislocations and slip bands in molybdenum single crystals

The characteristics of selectively introduced slip bands and individual dislocations were investigated. It was found that slip bands produced by indenting the (112) surface had three types of Burgers vectors concentrated at the two edges of the slip band while the middle of the slip band consisted of primarily the ± ½ [111] Burger's vector. Scratching the specimen with a needle almost parallel to the (112) surface in the [111] direction produced individual screw dislocations near the scratch mark. Similar scratches normal to the [111] direction produced fine slip bands with a ± 1/2 [111] Burgers vector
