Hi
Diffusion Creep involves the flow of vacancies and interstitials through a crystal under the influence of applied stress. A tensile stress increases the separation of atoms on grain boundaries that are normal to the stress axis, and the Poisson contraction decreases the separation of atoms...
Dear friends
I have tried to electroetch 1050 aluminum alloy by 5ml phosphoric acid + 95ml H2o under 1 to 10 volts. However, it was a complete failure even after etching for 6 min.
Please help me if you know how to overcome this problem.
Thank you very much
Best regards
