In this study, effect of boron nitride particles on the mechanical properties of aluminum composites
reinforced with BN particles was investigated. Experimental procedure was started with mixturing of
powders in the turbula mixer. Hot press was applied at 550 C in argon atmosphere. For characterization of
microstructure, scanning electron microscope (SEM) analysis was done. Compression test was applied for
determination of strength. Vickers hardness was used to measure hardness of samples.

Aim of this study is to investigate effect of titanium carbide nanoparticle contents on the mechanical
properties of the Aluminum/TiC composites. Aluminum and titanium carbide nanoparticles were mixtured
in the turbula mixer. After mixture process, samples were produced using Hot Press in argon atmosphere.
Scanning Electron Microscope (SEM) and X-ray diffraction were used for characterization. Compression
test was performed for determination of strength and also vickers hardness tests were carried out to
understand mechanical effects of TiC particles on pure aluminum.

In this study, effects of heat treatment on microstructure and structural properties of NiTi alloy were
investigated. In this sence, the depence of shape memory behavior of NiTi alloy was examined by changes
of heat treatment temperature and cooling conditions. Two group of specimens were used. One group was
deformed by 50% and the other group was deformed 75%. Heat treatment temperatures were chosen 5000C
and 600 0C. All specimens were cooled both in air and water to investigate the influence of cooling
conditions. Microstructures were examined using Scanning Electron Microscope (SEM). Also DSC and
XRD analysis were carried out for thermal and structural characterization.

The influence of microwave absorbing properties of polyvinyl butiral (PVB)/BaTiO3 composites were investigated in the 1-14 GHz. PVB/filler particles (BaTiO3) composites were prepared with 85/15, 90/10 and 95/5 mixture ratios via Ultrasonic Probe Sonicator method in solution. The complex permittivity (ε’- jε’’) and permeability (μ’- jμ’’) of the composites have been measured at different microwave frequencies in 1–14 GHz employing vector network analyzer (Keysight N9926A). The reflection loss (RL) of composites was calculated and evaluated using the theory of the absorbing wall. The results show that absorption is increasing as the fillers rate increase and thickness is decreased. This can be understood based on quarter
wave principle within the frequency range from 1 GHz-14 GHz for different thickness.
