| 英文摘要 | The dense Ni3Al with different boron and chromium addition was fabricated by the thermal explosion and hot extrusion (TE/HE) technology. Microstructure examination showed that Ni3Al contained fine grain structure (200 nm to 10 mu m). Analysis of X-ray spectra as well as transmission electron microscopy studies revealed that three phases present in all alloys: gamma-Ni, Ni3Al and dispersoids of Al2O3. With the addition of B, beta-NiAl phase and twinned Ni3Al formed, but in the B and Cr doped alloy, Cr rich phase and a spot of Cr7Ni3 particles with stacking faults inside were observed. In addition, dislocations with high density existed in all alloys. The mechanical test showed that the B and Cr addition resulted in significant improvement in mechanical properties, and TE/HE synthesized Ni3Al alloy owned more excellent mechanical properties, compared with the one synthesized by combustion.
