Engineering its microstructure requires high temperatures; as a result, most steel processing consumes significant energy. In the 1970s, scientists noted that some steels exhibited better properties when heat treated under a magnetic field\u2014but their ideas explaining this behavior were only conceptual. Understanding the mechanism behind this phenomenon could improve engineers\u2019 ability to control heat treatment, improving material processing and potentially lowering energy costs.<\/p>\n<p>\u201cThe previous explanations for this behavior were phenomenological at best,\u201d said Trinkle, the Ivan Racheff Professor of Materials Science and Engineering and the senior author of the paper. \u201cWhen you\u2019re designing a material, you need to be able to say, \u2018If I add this element, this is how (the material) will change.\u2019 And we had no understanding of how this was happening; there was nothing predictive about it.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Professor Dallas Trinkle and colleagues have provided the first quantitative explanation for how magnetic fields slow carbon atom movement through iron, a phenomenon first observed in the 1970s but never fully understood.
