“…As the NiTi content was continually increased, an additional shade of gray appeared, especially in the upper layers of the FGM that corresponds to Ni 3 Ti. Formation of all three Ni-Ti intermetallics is common when employing combustion synthesis for production of NiTi, especially when using the propagating mode (SHS) [37,38]. Phase analysis of the Ni-Ti-C system shows coexistence of Ni 3 Ti with NiTi and TiC as well as NiTi 2 with NiTi and TiC [39].…”

“…Some studies were focused on establishing the relationship between SHS and phase diagrams. It was found [6,7] that the products formed in the Ti-Co and Ti-Ni systems strictly corresponded to liquidus curves (Fig. 4).…”

The nature of SHS process was studied, and conditions under which equilibrium and non-equilibrium regimes take place for wave propagation and structure formation of SHS products are under consideration. The important role of cooling down time is shown. Depending on its magnitude, either autoannealing or autoquenching processes can take place in the products after combustion front propagation. The correlation between transition from non-equilibrium to equilibrium state of the product with prolongation of cooling time was examined as well as character of products and processes was indicated in dependence on relationship between the characteristic times of combustion, time of cooling down, and structure formation in SHS product.

“…In the matrix of all Ni 50−x Ti 50 La x alloys, the ratio of Ti and Ni atoms is very close to 1. According to the phase diagram of Ti-Ni binary alloys, the matrix is likely to be a near-equiatomic TiNi phase [16]. In all bright precipitates of the Ni 50−x Ti 50 La x alloys, only La and Ni are detected, and the atomic ratio of La:Ni is also close to 1:1.…”

The microstructure and martensitic transformation behavior of Ni50−xTi50Lax (x = 0.1, 0.3, 0.5, 0.7) shape memory alloys were investigated experimentally. Results show that the microstructure of Ni50−xTi50Lax alloys consists of a near-equiatomic TiNi matrix, LaNi precipitates, and Ti2Ni precipitates. With increasing La content, the amounts of LaNi and Ti2Ni precipitates demonstrate an increasing tendency. The martensitic transformation start temperature increases gradually with increasing La content. The Ni content is mainly responsible for the change in martensite transformation behavior in Ni50−xTi50Lax alloys.
