Computer model predicts how materials meet in the middle

Computer model predicts how materials meet in the middle. Watch a video of Imperial researchers explaining how they are predicting the structure of interfaces in materials, and why this is important - %0A " - Tuesday 16 March 2010 - By Colin Smith and Lucy Goodchild Predicting the way different materials fuse together at an atomic level in objects including iPods, computer chips and even ships may be possible using a new computer model, described in the March issue of . The authors of the study, from Imperial College London, say their new approach could help engineers understand and work out in advance how materials might behave. This could help them to design better materials with improved properties such as strength, flexibility or conductivity. When two different crystalline materials, such as metals or ceramics, are joined together, there is an interface between them where individual atoms have to arrange themselves into certain positions. The chemical composition of this interfacial region may also be different from that of either crystal. The structure and composition of the interface can have a significant impact on the overall properties of the material.
