摘要: In CuAlNi single crystals, amplitude-independent and amplitude-dependent internal friction due to phase transformation exhibits different temperature dependence in the range during direct transformation. An ADIF{sub pt} maximum is observed near M{sub s} temperature, suggesting that at least part of pt}, a pretransformational phenomenon, which may be associated with nucleation martensite dislocations {beta}-phase. The hypothesis both AIIF{sub separated into premartensitic transition components, allow one explain rather complicated experimental observations coherent fashion.
