I have plain strain compressed AA1050 Aluminum,in which i observe slip bands in deformed condition.I have done SEM and EBSD of samples.I want to know the slip systems active in a given grain.
Dear Aditya,
Once you know the orientation of a given grain with respect to the loading axis, and can see slip traces in a certain direction, you just need to combine the grain orientation with the visible trace direction. The easiest way is to plot the poles on a pole figure and superimpose the trace.
You may find the description in the given publication helpful, since it also deals with an fcc alloy in compression:

With plane strain compression, you have two constraints and can more easily fix the slip plane and direction.
Dear Aashranth,
I have done plain strain compression and doing DIC to identify Sleep trace isn't possible.Is there any other way its possible let me know?
Aditya Prakash , DIC is not necessary; if the slip traces are well developed you will be able to see them in EBSD maps directly - eg. in IPF maps (Fig. 3 of the publication), and more visibly in local misorientation maps (LAM, KAM etc.) This is shown in Fig. 7 along with the superposition of the poles.
DIC is only used here to image and count a large number of slip traces in a shorter time than EBSD.
