摘要：

The effect of Ni4Ti3 precipitates on the structure and transformation sequences in Ni-49% Ti alloy has been investigated using internal friction, electrical resistivity and electron microscopy studies. It has been confirmed that in the alloy without precipitates the transformation occurs following the sequence B2 --> R --> M on cooling and M --> B2 on heating with easily distinguished peaks on the internal friction curves and typical behaviour of the electrical resistivity, while the presence of the precipitates brings about complicated internal friction curves indicating either the appearance of two types of martensite or the transformation sequence: B2 --> B2 + R --> B2 + M --> M.
