However, the coarsened and less dispersive Ti〓Ni〓 precipitates do not affect the morphology of the R phase and provide the preferred nucleation sites for the martensite, but they prevent the martensite from its auto-catalytic nucleation and growth and, consequently, the martensite develops discontinuously in a clustering nature.
