Hi Everyone.
I recently stumbled upon an online bladesmith's version of Dr John Verhoeven's Book
Metallurgy of Steel for Bladesmiths & Others who Heat Treat and Forge Steel
In the preface he has kindly given permission for non-financial-gain download and printing of this amazingly instructive book:
"My professional career has been supported by publicly funded institutions. Therefore, I grant any user copyright permission to download and print a copy of this book for personal use or any teacher to do the same for their students. I do not grant rights to the text for commercial uses. The copyrights to all figures with citations belong to the original publishers. Copyright permissions were obtained for inclusion of these figures."
The book can be found in PDF format here. Our thanks to Dr Verhoeven for this amazing gift.
Hope you all find it as useful and interesting as I have.
