Some alloys show the deformation texture close to that of the annealing texture. What are the possible mechanisms for this specific outcome?

Some metals/alloys show a static recrystallisation texture close to that of the deformation one. These are usually not expected due to the oriented nucleation and oriented growth theories which...

Is it possible to synthesise relatively thick sheets (>150 micron) of nanotwinned copper?

I have tried a lot a literature regarding pulsed electrodeposition of copper to obtain nanotwinned microstructures. But all of these sheets (or foils) are limited in thickness (less than 50...

Why do variations occur in the linear elastic region of a tensile test when performed using molecular dynamics (LAMMPS)?

I am trying to perform tensile testing of a bulk copper box. But when I plot the results of the test, I get a slight curve in the elastic region of the stress-strain plot. Is this normal? Also I...

Is there a relation between sample thickness and recrystallisation and grain growth resistance?

If I have a deformed specimen and I used wire EDM cutting to cut the material into samples of different thicknesses. Assuming the HAZ from the EDM wire cutting is removed, if I were to heat treat...

How do we simulate a nanotwinned Copper microstructure using LAMMPS?

I would like to know how to create twin boundaries (code it) in a metal using lammps. I am try to simulate the effects of twin boundaries in strenthening of copper so I require twins in initial...

Is it possible to obtain copper without any annealing twins through processing?

In copper we observe annealing twins, growth twins or deformation twins regularly based on the processing history. Is it possible to process copper such that the twins are not nucleated or the...

Can anyone help with the definitions of coherent and incoherent twin boundaries in metals?

In metals if we say a boundary is coherent, it is understood that the atoms on either side of the boundary have a one-to-one matching bonds on the other side and for incoherent boundaries all...

Are all Sigma-3 boundaries coherent twin boundaries during EBSD mapping using TSL-OIM software?

It is seen in literature that Sigma-3 CSL boundaries are usually taken as twin boundaries and more importantly coherent twin boundaries. I am asking this since I am getting significantly...
