I blogged this item with a colleague's project in mind "Writing elementary materials science lectures"
The topics in this blog are up-to-date subjects, images are good but for educational material I believe our college and fellow IOM3 member will bring the necessary underlying scientific principles to light/
Anyway here is the blog link which may also be found by scrolling right down to the very foot of my page...
Metallurgy for dummies
I shall be pleased to pass on any further information on such approaches to our fellow materials science colleague.
Good luck and best wishes to all contributors
