   Abstract: Plane is the name of Platanus genus from the family Platanaceae (Platanaceae) that is the tall, thick-scaled tree species. The Ottoman plane or eastern plane (Platanus orientalis) is the endemic plant of Anatolia, and the western plane (Platanus occidentalis) is the endemic plant of North America. Both species’ hybrid is known as the London plane (Platanus hispanica). Eastern plane has been used for centuries in traditional Chinese medicine, Far Eastern countries and Iran for therapeutic purposes. Active compounds such as flavonoids [4], proanthocyanidin glycosides [8-10] penta-aromatic triterpenoids [11], tannin [12], phytol derivatives [13] and caffeic acid [14] which are found especially in plane leaf, are bioactive components that have a role in successful usage in traditional therapy. The ability of plane leaf to be effective in osteoarthritis and gout complaints directly depends on the bacterial population on it and harvest time.

   Abstract: Prealloyed NiTi and high purity Al powders were used in the study. Prealloyed NiTi powders and Al powders were mechanically synthesized for 210 minutes by mechanical alloying (MA) method. Respectively 2, 4, 6 and 8 % ratios of Al powders were synthesized in NiTi alloy powders via milling. Alloyed powders were pressed at 200°C and sintered at 1100°C for 2h. In determining and characterizing the properties of powders and sintered parts; SEM, Optical Microscope, XRD and DSC analyzes were applied, respectively. Optical Microscope images show the fine grains obtained in NiTi+Al 8% alloys. In XRD analysis B₂, B19, AlNi, Al₃Ni and AlNi₂Ti peaks were seen. The XRD results show the needed 2θ peaks could be achieved with sintering of NiTi+Al alloy system. The results show that the obtained parts will be used in implant technolgy with their fine and pure structures.
