This week another segment of my presentation, recorded in a slightly different format this time (hopefully for the better, the previous one on SAXS on catalysts can be seen in this post<\/a>). This time, I discuss an application of SAXS application in the field of metallurgy. To be honest, before I started at NIMS, I was not familiar with the use of SAXS in to study metals and alloys. However, thanks to Masato Ohnuma<\/a> (my mentor at the time) and Julian Rosalie<\/a> (an excellent microscopist in metallurgy whom I interviewed for this video<\/a>), I have been quickly brought up to speed with the finer details of the effect of nanostructures in metals.<\/p>\n

To my surprise, it turned out metals were not the static materials I was expecting. Indeed, small nanostructures can grow in the metals at moderate temperatures (<200\u02daC, see f.ex. this paper<\/a> (also on arXiv<\/a>)), and we also have evidence for such “ageing” behaviour in room-temperature alloys (see our most recent addition to arXiv<\/a>). As you would expect, this structure can very much affect the mechanical properties of the material.<\/p>\n

So in today’s video, I show a very short summary of the work for the study of ageing at moderate temperatures of MgZn alloys. Please enjoy and share!<\/p>\n
