As the heading says ...

I have been experimenting with laser cutting of blade blanks, and in steels (so far) I have gotten a hardend region around the perimeter of the profile, maybe 0.015 to 0.020 in. I figure I can re - anneal the steel to take this hardening out, but I am wondering about what happens if you try to laser cut Talonite? Do you get this same hardend zone around the perimeter? If you do, how do you anneal and then reheat treat the material? Actually, since I am asking - does the same thing happen with Titanium? Assuming it does, how do you fix that?

Thanks for the info.

Q- can't help with info, but would suggest you ask over at the ShopTalk Forum as well. Lots of knowledgable, helpful folks over there.:)
 
Talonite laser cuts beautifully. There is no noticeable HAZ with Talonite, and it does not affect the hardness of the material.
 
When titanium is laser cut it does leave a very thin heat affected zone(HAZ). The HAZ is very hard. Plasma cutting also leaves a HAZ. Waterjet does not leave HAZ but is not as accurate as laser cutting.
 
I figured that laser would leave a HAZ on Titatium as well - can you re anneal the titanium afterwards?
 
I got the following information from Timet website:

ANNEALING
All product forms of TIMETAL 6-4 can be annealed at temperatures from 1225° to 1600° F (660° to 870° C) in one-half to four hours. Cooling rates can be air cool or slower.
