Nil Ductility Temperature of ASTM Materials

Post by neo »

Where can we refer Nil Ductility temperature of ASTM materials?
Are they referred in construction codes?

You will not be able to have these temperatures listed somewhere for all the materials.
This represents the limit of a material beyond which the behaviour of a material is brittle in nature.
The value is determined against ASTM E208 or E23, and then gets documented.

Yes, the references available within the impact testing reports would provide you with this temperature.
You would not be able to find them in a tabulated form within the construction codes.

In that case how we can relate MDMT to Nil Ductility Temperature?
