Phase Stability by the Artifical Concentration Wave Method

摘要

Phase stability can be examined by means of concentration waves. X-ray diffraction techniques are utilized to study the growth and decay of the concentration waves, from which critical temperatures can be determined. Artifical composition modulated foils (of short period) examined include Cu/Ni, Cu/NiFe, Cu/NiCr, and Cu/NiSn. The theory of static concentration waves can be employed to predict phase structure, stability, critical temperature, and kinetics. (ERA citation 12:035149)
