Neutron Transmission Strain Measurements on IMAT: Residual Strain Mapping in an AlSiCp Metal Matrix Composite
R.S. Ramadhan, W. Kockelmann, A.S. Tremsin, M.E. Fitzpatrickdownload PDF
Neutron transmission strain measurements were performed for the first time at the IMAT beamline, ISIS, UK, in order to demonstrate the capability and measure the accuracy of the new instrument. A novel Bragg edge strain analysis technique based on cross correlation is introduced as an alternative to a Bragg edge fitting technique. Neutron transmission measurements were performed on an AlSiCp metal matrix composite, and the result is compared with the neutron diffraction result on an identical sample, showing good agreement between the two. The advantage of using the proposed cross correlation Bragg edge strain analysis technique over edge fitting is discussed.
