DBTT Ductile Brittle Transition Temperatures Tables
DBTT Ductile Brittle Transition Temperatures Tables
(OP)
Does anyone have Ductile Brittle Transition Temperatures Tables for steels. I found one on the web but not sure if I can trust.
Particularly I'm looking for a material that becomes brittle at -40C(F).
Thank You in advance

Is that something that do-able in a sense can force be controlled in brittle region or once it goes into brittle it cracks at any force?
Sorry, a little novice with brittle properties.

How quickly material get brittle also is a variable.
What toughness do you need? What is the shock or impact loading that are working with?

I have experimented with Aluminum and at room got 275 lbs pull and at -40 it was 285 lbs
I would like to find a material that will do the opposite go from 225 to say 150 lbs.
The only physical property I have researched that gets weaker with colder temperatures was brittleness.
The system is a continuous pull so there is really no shock, actually there is but I'm not using it in my calcs. but I can start to.
Looking for a chart of 1010-1080's steels their DBTT, may be strength on y-axis and temp on the x-axis.

There are some that change less.
If you get into the brittle region then you will either have higher strength (when it doesn't fail) or zero strength (when it cracks).

That's kind off the feeling that I had, thank you for confirming that.
Still a little itchy to try it out in the lab. I found a goofy DBTT chart that at -40C(F) between 1040 and 1060 steels enter brittle zone, can that be confirmed. I don't have smart metallurgical books.
