In this study, it was aimed to production titanium alloy implants, which are widely used in the biomedical industry, as foamed materials under different mechanical alloying and sintering conditions using the powder metallurgy method Tİ6Al4V alloy is good mechanical properties, good biocompatibility properties and good corrosion resistance used as hard tissue replacements and implants. Similar mechanic properties with bone are expected from the implant to work coherently for long cycles of use and without any failure. Especially, elastic modulus of implant must be similar with bones, if not, some damages at bone surface and fallowing repeats of implant surgeries are reported. This situation has a destructive effect on health, finance, and comfort of the patient/user of the implant. In this study, powder metallurgy and space holder removal methods were used to produce porous Ti6Al4V specimens. Throughout the project study different space holder materials and binder agents were used. As weight percent, 20%, 30%, 40%, 60%, 70%, 80% porous specimens were pressed at uniaxial press machine, and sintered to the 850 ºC at argon atmosphere in furnace to reduce the oxidation to the level as low as possible. The E-Modulus values of the specimens reached the desired values with increasing porosity. It was obtained as 88 MPa in the specimen with 80% porosity, decreasing inversely proportionally, especially from the 60% porosity rate.

Being one the modern high quality industrial welding process especially for stainless steels and titanium alloys. TIG welding process has been has been researched for decades in order to define its parameters such as welding speed, current and arc length to improve the weld penetration. Hence it is a popular technique for joining thin materials-the thickness of the work piece is in general restricted to less than 6 mm-in manufacturing industries. In this study, AISI 321 and 316L stainless steel sheets of 4 mm of thickness were used as welding metals. Thus, AISI 321 welding metal couples, AISI 316L welding metal couples and AISI 321 and 316L welding metal couples were selected to ensure a combination of similar and dissimilar metals. The filler metal rod was made of 316L SS. The specimens were cut in dimensions of 150 x 30 x 4 mm as using an abrasive cutter, then the V weld butt joint configuration with single groove of 37.5 o ± 2.5 o groove angle by a lathe machine. The welding current was 200 A and TIG welding process was performed manually in single under argon shielding gas atmosphere. After TIG welding process, the separate metallographic preparations, then microscopic and macroscopic examinations of the specimens, also hardness measurements of specimens were made. The rest of them was shaped for tensile strength measurement using Instron Universal Testing Machine. The hardness of the specimens were observed being altered in the range of 145-151 HRV(average) and their tensile strength values in the scale of 345-400 MPa (average).

Buckling characteristics of basalt fiber reinforced epoxy composite laminates  Basalt fiber reinforced epoxy composite fabrication with nano clay particle additive  The effects of nano clay particles on the buckling properties of basalt composite laminates Figure A. The production flow and testing of basalt fiber reinforced composites with NC particlesPurpose: Even though many studies were performed on mechanical properties of the fiber reinforced composites incorporating nanoparticles, studies on buckling behavior of nano clay particle filled composites are still infancy. To the best of authors' knowledge, the buckling characteristics of basalt fiber reinforced composites containing NC particles has not been studied yet. Therefore, in this study, the effect of NC particle addition on axial and lateral buckling properties of basalt fiber reinforced composites was investigated at different NC weight contents. Theory and Methods:Basalt fiber reinforced composite samples fabricated by vacuum assisted resin transfer molding (VARTM) were prepared at various NC particle weight concentrations (0, 0.5, 1, 1.5, 2 and 3 wt.%). Prepared samples were experimentally loaded in axial and lateral direction to determine effects of NC particles on buckling properties. The effects of the NC particles on the fracture characteristics were also analyzed by taking images on a scanning electron microscope (SEM). Results:The results revealed that the most improvements on the buckling behaviors of samples were achieved from 1wt.% NC addition. The improvements were 48.1% and 39.56% for the axial and lateral critical buckling loads, respectively. Slight decreases in buckling characteristics were observed in samples containing more than 1wt.% NC particles due to poor interfacial bonding caused by agglomerations and exfoliation of nano particles at the epoxy/basalt interfaces. Conclusion:It has been determined that the use of NC particles in epoxy based matrix system significantly increases the buckling properties of basalt fiber reinforced composites, and it has been proven that it is possible to evaluate the materials of the system members that may be exposed to high axial or lateral buckling loads.
