How can I generate the Grain Boundary Character Distribution (GBCD) from the ODF files (.raw, .rrw or .TXD)?

In my work, the textures were determined by measuring three incomplete pole figures {110}, {200} and {211} in the back reflection mode by a Bruker D8 Discover X-ray diffractometer. The file...

What is the formation mechanism for the primary Widmanstätten ferrite plates which grow directly from austenite grain boundaries?

It is known that ‘secondary Widmanstätten’ ferrite can be described as laths of plates branching into the austenite from the allotriomorphic ferrite along the parent austenite grain boundaries. In...

Hi Shabalin, Thank you for your help.

Ni and Si are the diffusion barriers, they retards the diffusivity of carbon in the matrix hence Si (3%W) cannot promote the diffusion....infact can reduce the diffusion coefficient.................
