The effect of Zr and ZrB2 additions to NdFeB alloys
… 1.0 at% of ZrB2 have been investigated by EPMA (Electron Probe Microanalysis) and TEM (Transmission Electron Microscopy). 1.0 at% of ZrB2 has been found to be very effective in suppressing the formation of free α-Fe dendrites during solidification, but the excessive ZrB2-type needles formed in …

Transmission Electron Microscopy Studies In Shape Memory Alloys
… martensitic transformation can be induced by temperature or stress between a cubic (B2) austenite phase and a monoclinic (B19') martensite phase. Ni-rich binary compositions are cubic at room temperature (requiring stress or cooling to transform to the monoclinic phase), while Ti-rich binary …
