Abstract

In this study, 10% Nb and 10Sn additions of titanium were produced by mechanical alloying technique at different times up to 30 hours and sintered for 2 hours at 1000 °C after the powder were pressed. Obtained samples were examined by X-ray diffraction experiments (XRD), scanning electron microscopy (SEM), hardness, density and ultrasonic tests to investigate the microstructural and mechanics. Results obtained from the study show that the particle size decreases due to the increased mechanical alloy time. Due to the solid state reaction during mechanical alloying, niobium and tin elements have been found to form solid solutions in the titanium lattice. It was determined that the hardness values obtained after sintering were higher than the hardness values before sintering and the reason for this was due to the presence of TiC second phases formed in the microstructure during sintering. The relative density value has been calculated and it is seen that the details obtained between 5 and 20% pores. Finally, with the increase of the mechanical alloying time, the elastic modulus values were decreased while the closest elastic module values were determined after the 30-hour mechanical alloying time. These results show that Ti10Nb10Sn alloy has the potential to be used as a new generation biomaterial.

Özet

Bu çalışmada titanyuma ağ.% 10Nb ve 10Sn ilaveleri yapılarak 30 saate kadar farklı sürelerde mekanik alaşımlama tekniği ile üretilmiş ve elde edilen tozlar preslendikten sonra 1000 0C de 2 saat sinterleme işlemine tabi tutulmuştur. X-ışını kırınımı (XRD), Taramalı Elektron Mikroskobu (SEM), sertlik, yoğunluk ve ultrasonik analizleri yapılarak elde edilen numuneler mikroyapısal ve mekanik olarak incelenmiştir. Çalışma sonucunda elde edilen sonuçlar, artan mekanik alaşımlama süresine bağlı olarak toz boyutunun azaldığını göstermektedir. Mekanik alaşımlama esnasındaki katı hal reaksiyonundan dolayı niyobyum ve kalay elementlerinin titanyum kafesinde katı çözelti oluşturduğu görülmüştür. Sinterleme sonrası elde edilen sertlik değerlerinin sinterleme öncesi sertlik değerlerinden yüksek olduğu ve bunun sebebinin ise sinterleme esnasında mikroyapıda oluşan TiC ikinci fazlarının varlığından kaynaklandığı tespit edilmiştir. Bağıl yoğunluk değeri hesaplanmış ve elde edilen numunelerin % 5 – 20 arasında gözenek barındırdığı görülmüştür. Son olarak mekanik alaşımlama süresinin artmasıyla elastik modül değerleri azalırken 30 saatlik mekanik alaşımlama süresinden sonra kemiğe en yakın elastik modül değerleri tespit edilmiştir. Elde edilen bu sonuçlar Ti10Nb10Sn alaşımının yeni nesil biyomalzeme olarak kullanım potansiyeli olduğunu göstermektedir.
