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.
