Is it possible to use the same concept with pearlitic wires to manufacture a component with 3mm thickness and a UTS point of more than 3GPa?

And also what processes are possible to be utilised? Since the geometry is feasible by stamping, using extrusion is difficult in order to obtain the desired geometry. What about high temperature...

Can someone use the Inverse Pole Figure to seperate grains that have taken up plastic deformation during Rolling operations?

I am using the Inverse Pole Figures (with respect to the RD) to correlate the resulting fatigue performance to the initial orientation of specific grains in an AA2024 T3 alloy. It seems straight...
