Furthermore, inferring from the poor orientational relationship between MC carbides and the matrix, it is more likely that the carbides represent the growth of existing carbides rather than new nucleation.

In this paper, ductile NiTi particle (NiTip) was added in pure Al alloy by ball milling and spark plasma sintering (SPS).
