摘要: Abstract The effect of aging on transformation sequence, microstructure evolution, hardness change and pseudoelasticity (PE) Ti50.1Ni49.7Si0.2 ribbon is investigated. aged at 500 °C for ≧1 h undergoes a two-stage B2→R→B19′ during cooling. the are closely related to its composition. matrix becomes Ni-rich because high Si content low Ti/Ni ratio. A very density Ti3Ni4 precipitate observed in ribbons ≧1 h, which gives hardness. Nanoindentation tests indicate that 15 min has maximal 5.5 GPa 336 h decreases 4.0 GPa. PE recovery improved from 55% 75% under 100 mN loading after 15 min. experimental results show adjusting composition TiNi can effectively modify microstructure, increase still retains excellent recovery.
