摘要：
The system (Fe0.88Mn0.12)(1-x)Al-x has been investigated in a concentration range from 5 to 14 at.% Al. We applied Mossbauer spectroscopy in the temperature range from 4 up to 900 K and X-ray diffractometry at room temperature. The as-cast samples show a bcc phase for all concentrations and exhibit broadened six-line Mossbauer spectra typical for disordered alloys. The Mossbauer spectra during a high temperature treatment show dramatic changes. These are due to ordering processes appearing at temperatures above 700 K. As an example of the observed changes, we present results obtained for the alloy with x = 14 at.% Al.
