| 中文摘要 | Microstructures of beta l' martensite around Xs precipitate in a Cu-Al-Ni-Mn-Ti shape memory alloy have been studied by high resolution electron microscopy. Both formation of self-accommodation martensite variants and change in 18R stacking sequence to 2H sequence were often observed to occur simultaneously around Xs in samples water-quenched from 1223K. A new orientation relationship between 2H and 18R martensite has been found: (12 (8) over bar)(18R)//(12 (1) over bar)(2H) and [231](18R)//[2 (1) over bar 0](2H). Analysis of composition of martensite around and away from the Xs precipitate shows that enrichment of Al in the matrix close to Xs account for the change in the martensite stacking sequence. Meanwhile, Xs was found to have different composition with X-L precipitate and could be termed as (Cu, Ti)(2)NiAl. (C) 1997 Acta Metallurgica Inc. |
