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...

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.

How to define and get results (stresses) for certain points of a model in abaqus, using python? When the size of the model changes?

I want to do a parameter study of a aixsymmetric cylinder in Abaqus. I want to create several jobs where I get the stresses for 3 different points in my model. These points are defined. I wrote a...

Benefits of the 24 welled plate?

We have always used the 96 welled plate, the 48 welled plate but apparently there is much evidence on the 24 welled plate and above all its benefits.It states it is the same you would use on ELISA...
