Abstract :
In this research, TiNiCu alloys are developed
using the powder metallurgy route. Two batches are
prepared with varied compositions. Sample one holds
Ti50 Ni50 by atomic weight. Ti50 Ni45 Cu5 composition
is set for second sample and Ti50 Ni40 Cu10 for the
preparation of third sample.The treatment of both the
batches are done in different environmental conditions.The
development methodology is opted based on the ability
to produce porous alloys of varied grain sizes and
densities. Several other techniques like Vacuum Arc
Melting, Spark plasma Sintering are also used in the
industry for obtaining high porosity levels in the
developed SMA alloys. Here, the effect of variation of
porosity on other mechanical and physical markers is
also studied. Non-destructive characterization
techniques are implied to identify the developed NiTi
alloys and to access the behavior. XRD, DSC and Micro-
hardness tests are performed and the results are
analysed and compared with the previous research
studies.
