摘要：

Effect of the temperature of injection on the quality of spinning ribbons of Ni-Al-based alloys is studied. The phase composition of the ribbons and corresponding bulk materials are investigated and compared. As revealed, the temperature of injection is not related directly to the quality of ribbon and the conditions of gamma-phase (L1(2)) formation. Alloying elements can be divided into three. groups depending on their influence on the structure and phase composition of ribbons. Influence of the alloying elements on ribbon of Ni-Al-based alloys is similar to that for bulk materials excluding Cu. The best-quality surface of ribbon is achieved by the alloying with Zr, which forms ternary intermetallic compound, and Cr, which forms pseudobinary eutectic. Complex alloying with Zr and Co allows obtaining a good ribbon of 64Ni-30Al-3Co-3Zr, which undergoes martensitic transformation.
