Summary on Grant Application Form |
|
Dislocations control plastic behaviour. Impurities can interact strongly with them - not simply as precipitates but even in more homogeneous distributions. In addition to their role in pinning dislocations, impurities may create dislocations when they condense (e.g. in the case of H in Si). This could have profound consequences for sudden loss of brittleness and it should be generic ( extending to H2O in quartz, HF in ice and H in diamond). Other impurity interactions could give rise to novel chemical reactions within dislocation cores. First principles calculations and elasticity theory analysis will be applied to establish these 'mechanochemical' effects.
