摘要
The obvious residual strains were observed at the interface of Gr(C)/Mg composite. The lattice parameters in the strained area were determined by fitting the distances between a projecting center and HOLZ lines in CBED patterns with the least square method. Because it is difficult to ascertain the accurate position of the projecting center, an experimental center was set up and its coordinates relative to the projecting center were introduced as system parameters. In addition, an analysis of the distribution of the residual strains in the interface and matrix was carried out with the LACBED technique.
