There are major difficulties in creating novel nanocrystalline structures that have a combination of properties appropriate for large-scale applications. An important requirement is to be able to manufacture nanocrystalline components, which are large in all dimensions on their macroscale whilst retaining their nano-scale structure. In addition, the material concerned must be cheap to produce if it is not to be limited to niche applications. Severe plastic deformation has not succeeded in this respect since grain growth cannot effectively be suppressed during consolidation processes. Therefore, processing bulk nanocrystalline materials for structural applications still poses a big challenge. Here we describe a design strategy and alloy development effort currently being explored in the modern steel industry, that have the potential to create extremely strong and affordable nanocrystalline engineering steels.
