This article presents the synthesis and characterisation (Fourier transform infrared spectroscopy, 1 H NMR and 13 C NMR spectroscopy, CHNS (carbon, hydrogen, nitrogen, sulfur) analysis, atomic absorption spectrometry, and single-crystal X-ray diffraction) of a single source molecular precursor 1-(2-fluorolbenzoyl)-3-(3-ferrocenylphenyl)selenourea (M2F). This precursor has been used for the fabrication of FeSe thin films by aerosol-assisted chemical vapour deposition (AACVD) in the presence of different concentrations of two different surfactants (triton and span) keeping all other conditions the same. Fabricated thin films have been characterised with powder X-ray diffraction, scanning electron microscopy, and energy-dispersive X-ray spectroscopy. The interaction of the surfactants with the precursor (M2F) has been evaluated with cyclic voltammetry and UV-vis spectroscopy.

Elgiloy is Co based alloy (40wt%Co, 20wt%Cr, 15wt%Ni, 14wt%Fe and 7wt%Mo). It was strengthened by cold work and is capable of additional hardening by aging. The effects of solution treatment, cold working and age-hardening on the microstructure of elgiloy were investigated using optical microscope, scanning electron microscope (SEM) and transmission electron microscope (TEM). As rolled strips were solution treated at 1065°C/1hr. These solution treated strips were then reduced 50% by cold rolling. After cold-deformation both є-hcp phase and fcc deformation twins are also considered to coexist at room temperature. The cold worked strips were then age hardened at (450-600)°C. The age hardened strips showed formation of additional є-phase (via α f c c є h c p transformation).

The functional fatigue behavior of Ti50Ni30Cu20 (at. %) shape memory alloy was investigated after subjecting to cold working and heat-treatment. Copper addition modified the phase transformation behavior with the introduction of B19-phase in the binary NiTi alloy. It was observed that aging after annealing and thermal cycling (-60 to 100)°C significantly effect the transformation temperatures. Observations in optical microscope and scanning electron microscope reveal inhomogeneity in the composition in the form of coarse Cu+Ti-rich precipitates. Investigations under transmission electron microscope showed growth of internally twined martensitic plates in solution treated sample. The phase transformation temperatures were determined with differential scanning calorimeter. The transformation temperatures were shifted towards lower side. Dislocations introduced during cold working and fine precipitation after aging, may be responsible for this change in the transformation characteristics of the material.
