摘要: The effect of wheel speed on microstructures Ti-48%Ni (mole fraction) melt-spun ribbons was investigated by X-ray diffractometry, scanning electron microscopy and transmission microscopy. When the is 26 42 m/s, as-spun are completely crystallized to Ti-Ni B2 phase. Ti-rich plate precipitates lying {100} planes observed in ribbon fabricated with a m/s. spherical Ti2Ni at grain boundaries Amorphous phases coexist 52 uniformity size heat treated decreases increasing speed.
