How can I import residual stress profiles into Deform?

Hi all, I want to import the residual stress profiles along the rolling and transverse direction into the Deform and also extrude those over the whole plate. Would you be able to point out how to...

Is there any technique to minimise the residual stresses in a plate without heating the sample?

I have a 30 mm thick plate AA7050 alloy and I want to reduce the residual stresses without altering the microstructure; so I cannot heat up the specimen. What techniques are out there? Is it...

Why there is a preference for plotting IPF maps over Euler maps in EBSD?

I am inspecting some machined specimens and I noticed not all grains and misorientations can be seen in the 3 IPF maps; while Euler mapping reveals quite well both -even though there might be some...

Hi, is it possible from an Inverse Pole Figure to quantify which grains are hard and which grains are soft?

Can we do such a quantification both for FCC and BCC crystals?

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...

How can someone increase both the strength and deformability of a metallic alloy but at the same time achieve a high yield to UTS ratio?

In most cases, scientists design a low yield deformable matrix which strengthens via phase transformations, twinning etc. However in many engineering applications a low yield point is not desirable.

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...
