Bainitic precipitation and its effect on the martensitic transformation in the Cu-Al-Ni-Mn-Ti shape-memory alloy

Bainitic precipitation and its influence on the martensitic transformation in the Cu–11.9Al–5Ni–1.6Mn–1Ti (wt %) shape-memory alloy has been observed in situ using X-ray diffraction and transmission electron microscopy. Bainite was observed to be precipitated when the alloy was aged at 553–700 K. Th...

Description
Summary:Bainitic precipitation and its influence on the martensitic transformation in the Cu–11.9Al–5Ni–1.6Mn–1Ti (wt %) shape-memory alloy has been observed in situ using X-ray diffraction and transmission electron microscopy. Bainite was observed to be precipitated when the alloy was aged at 553–700 K. The orthorhombic distortion of the precipitated bainite decreased with increasing ageing temperature and time. The bainitic precipitation strongly decreased the martensitic transformation temperature, and changed the martensite from faulted M18R1 type to twinned 2H type.
