I completed the course in 1 session, you could split up the course into smaller portions, if you can spend 20 minutes at a time.
I think this short course is an OK introduction to steel, and to the EDX technology. The course can be viewed as an enhanced lecture, since at the end of each short segment there is a little interactivity, in the form of some multiple choice questions or interactive graphics.
The material is really simplified, the major take homes are; the importance of steel, that it’s a versatile material, why it is the ultimate engineering material, what sort of things control the properties.
The course is quite short for such a large subject matter, so of course it’s rather simplified. I think in a few areas it is too simplified and might be misleading. An example of my concern would be the explanation of how quenching effects the microstructure, nothing about martensite phase is mentioned, only that quenching “freezes in the structure”. The approach is rather like the simplifications that take place in teaching physics were you find out at each level that everything you were taught to date, so I hope people watching the video would be motivated to study further about steels or metals.
Anyway these people seem happy:
So well done to Mark Miodownik and Tenaris for this innovation.
