1084 quenching, just the blade?

Page: I believe that the frontier that awaits is the relationship between transition zones and the adjacent structures.
All of my technical articles are peer reviewed by professionals who have actually worked in the field I am addressing in the particular article. They are not simply men with degrees who only regurgitate what they have read in the textbooks but professionals who look to the future rather than stand safely on tradition. One thing we have learned is that much of what we have learned has been learned in the past by others before us.

My series on myths is intended to be a history of many discussions of what was once accepted as fact and at one time seriously debated. I write about them because many of the new generation have had no experience of what was once traditional knowledge.

One of our students is doing some post graduate work describing what he learned in a seminar last January. When his report is finished I hope to share it with those who are interested, with his permission.

One goal that Rex and I made when we started our nearly 20 years of study is to keep the language simple and understandable for those who have not had the benefit (if it is a benefit) of the vernacular of the science of metals. The goal of keeping it simple to describe and understand has had great benefit to us in our work, this goal has greatly helped us to understand what for and why.

It is not the microscope that projects the future, but only tells us what happened, it is up to us to build the future knife. Every knife maker has in his shop every thing he needs to test knives for the function he intends them to perform.

so profound platitudes and self promotion aside, what does your analysis of the microstructure of your tangs tell you?

Oh!... Here we go with the microstructures again...

Doesn't anyone care about the macrostructure?

macrostructure
: the structure (as of a body part) revealed by visual examination with little or no magnification

noun
1.
the gross structure of a metal, as made visible to the naked eye by deep etching.
2.
an overall organizational scheme, as of a complex piece of writing.
3.
any overall structure, as a gross anatomical part.

Let's try to think more "macro" for once.

Sun Shaddow: To put it simple, the tangs are strong, with sufficient force will bend, twist and can be depended upon. Need I know more?
 
Tai,
all cosmic waves aside, any macrostructure is only as good as its smallest point of potential failure, if you understand and control your microstructures you can ensure the integrity of the macrostructure and make sure your blades perform as well as they look

Exactly!

... so what else is new about that?

...The micro bears witness to the macro, and the macro bears witness to the micro.

It works both ways. :)

The microstructures (plural) and the macrostructure (singular) essentially add up to the same thing... the "macrostructure".

… hope that’s not too cosmic. :)
 
I read the first couple answers and did a full quench. I just now came back and saw this turned into a three page forum. I have learned a lot. Thanks guys.
 
WAIT!..... what temperatures and what type of quenchant?..... We can always find sumpin' wrong wid it!:p

This is what worries me about you guys. Last night I looked down at the two plane blades and two knife blades I have almost ready for HT and I realized they are four different alloys!!??!!??
 
What alloys?

One plane blade is junk steel, an old leaf spring, 2" wide, 4" long, <3/16" thick.

One plane blade is O1, 2" wide, 4" long, 3/16" thick.

One knife blade is 1095, a 4" drop point, 3/16" thick.

One knork (I think that's what it's called, combination knife/fork I'm making for my dad who had a stroke a couple of years ago) is 1084, >1/8" thick, 5" blade, curved with fork tines instead of a point.

The first three were undertaken before I learned that a beginner ought to be starting out with 1084. If I had any common sense at all I'd get someone else to do my HT for me but everyone who knows me knows I don't have good sense.:o
 
They'll all be fine heat treating together. O1 would benefit from a longer soak but you'll hardly know the difference. I would nail em all at 1475F-1500F.

We only pick on Ed and Tai because they're famous.... and we're not.
 
Thanks Rick, my getto forge is really terrible. Hard fire brick left over from a fire place stacked on top of a 100,000 BTU fish cooker. Heat is really uneven but I do have a digital thermometer and ceramic probe I got from Auberins. If I keep each one moving around in the forge to try to keep the heat as even as possible will I be OK? I doubt I'll be to achieve even heat throughout the longer knife blades. Should I just try to HT the edge?
 
If you can, get a thickwalled pipe and lay it across the FCF(fishcookerforge) it will help distribute the heat. Move your blades inside the pipe. I stole that trick from my good buddy Tai Goo. There are other things you can accomplish with that pipe with regard to atmosphere and temperature control. Here is the one I made... Muffle Pipe Rig
