The behavior of texture formation during high-temperature deformation in AZ80 magnesium alloy is investigated. Three kinds of specimens were machined out from rolled plates. The plane strain compression tests were conducted at various deformation conditions – temperature, strain and strain rate. After compression deformation, texture measurement was carried out on the mid-plane section parallel to the compression direction by the Schulz reflection method and EBSD measurement. The maximum values of the flow stress are observed in all the cases at the true stress – true strain curve for three type of specimens. It is found that the main component of texture and the accumulation of pole density vary depending on deformation condition and initial texture. Six kinds of crystal orientation components have been observed after deformation in total. (0001)<10-10> is formed regardless of the initial texture.
