You can implement XRD experiment. After that you will obtain a diffractogram, in which you should compare integral intensity below amorphus halo and below all curve. It will be the degree of amorphization. But it's just an estimation.

Dear Dr. Madhusudan Roy 

Have a nice time and good day

You can get  excellent information by using  XRD measurements.

The appended papers may help you in your study.
