Experiments with the Bubble Model of Metal Structure 1952 - Sir Lawrence Bragg, W.M Lomer, J.F. Nye
Sir William Lawrence Bragg begins the film by describing the close packing structure of metals.
A demonstration goes on to show how bubbles on a surface of liquid can show the same structure as metals; this is a bubble raft experiment. The rest of the film, narrated by Bragg, uses bubbles to demonstrate the idea of dislocations in the structure of metals and how these occur at the points of greatest stress. The bubbles help to show how dislocations occur through rapid crystallisation and through collapse within a structure to create a hole. The bubble raft is further used to demonstrate how dislocations can correct themselves by pairing up or leaving a vacancy in a row within a structure. Crystal Boundaries are further described and demonstrated through the use of a bubble raft, showing how they might exist were two extremes meet. This can be were angles are or where disordered deformations occurs.
