Metallography of a Modern Pattern-Welded Steel Knife

Currently available as a free down load is an article in this month's Advanced Materials & Processes detailing the metallography of a pattern-welded blade welded up from W-2 and 203 E pressure vessel steel (.14 C, .58 Mn, & 3.43 Ni). The documented rapidity of carbon difusion is interesting. Thought folks here would enjoy it. This should take you directly to the article: http://asmcommunity.asminternational.org/s...21e2963ed861895

 

Or go to ASM International, look for Advanced Materials & Processes, click on the February issue and the list articles should come up. The title of this one is: Metallography of a Modern Pattern-Welded Blade by Thomas Nizolek

I met Tom at a local ASM chapter meeting in Philly. As I recall, he was a student and needed something for a senior project. He made the pattern welded knife - then cut it up (seems a real waste). He then wrote the results up and the professor recommended an article for Advanced Materials and Process. Good stuff.

Cutting them up is the only way to see what's in there, Scott. ;)

 

I know - but it is too bad because it was a nice piece of work. I am surprised he didn't just forge some cable and look at it.

Wow. Thank you for posting this article. I've been forging damascus since 1989, but I never understood the that carbon migrates but nickel doesn't during forge welding.

 

Cool post. Thanks again.

"It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood, who strives valiantly; who errs and comes short again and again; because there is not effort without error and shortcomings; but who does actually strive to do the deed; who knows the great enthusiasm, the great devotion, who spends himself in a worthy cause, who at the best knows in the end the triumph of high achievement and who at the worst, if he fails, at least he fails while daring greatly." -- Theodore Roosevelt
