The scope of the present study is to investigate the change of ultrasonic velocity with the physical and mechanical properties of Ni-Ti-WC composites. Since the materials used in the aerospace and automotive industries are exposed to high temperatures, friction and high stresses, the need for metal matrix composite materials used in manufacturing applications such as cutting discs and inserts has increased rapidly. Ni-Ti metal matrix composites reinforced with WC were circularly shaped in uniaxial hydraulic press. A mixture of 30% Ni, 2% Ti and 68% WC powders was sintered at 1000°C-1400°C with argon atmosphere in a tube furnace and were fabricated by electroless plating technique. XRD (X-Ray diffraction, SEM (Scanning Electron Microscope), compressive testing, hardness and ultrasonic velocity measurements were employed to investigated the mechanical and physical properties of specimens. Experimental results showed that ultrasound velocity values increased polynomial linearly with increasing sintering temperature. In addition, the fact that the highest sintering temperature resulted in 429.1HV hardness at 1400°C is an indication that the structure has become more robust and compact. The change in ultrasonic velocities with increasing sintering temperature is evidence of a better bonding of the structure.

Bu çalışmanın kapsamı, WC esaslı kompozitlerin fiziksel ve mekanik özellikleri ile ultrasonik hızın değişimini araştırmaktır. Havacılık ve otomotiv endüstrilerinde kullanılan malzemeler yüksek sıcaklıklara, sürtünmeye ve yüksek gerilimlere maruz kaldığından kesme diskleri ve kesici uçlar gibi imalat uygulamalarında kullanılan metal matrisli kompozit malzemelere olan ihtiyaç hızla artmıştır. WC ile güçlendirilmiş Ni-Ti metal matrisli kompozitler, tek eksenli hidrolik preste dairesel olarak şekillendirildi. %30 Ni, %2 Ti ve %68 WC tozlarından oluşan karışım 1000°C-1400°C'de argon atmosferinde tüp fırında sinterlenmiş ve akımsız kaplama tekniği ile üretilmiştir. Numunelerin mekanik ve fiziksel özelliklerini incelemek için XRD (X-Işınları kırınımı, SEM (Taramalı Elektron Mikroskobu), sıkıştırma testi, sertlik ve ultrasonik hız ölçümleri kullanılmıştır. Deneysel sonuçlar, artan sinterleme sıcaklığı ile ultrason hız değerlerinin polinom lineer olarak arttığını göstermiştir. Ayrıca en yüksek sinterleme sıcaklığının 1400°C'de 429.1HV sertlik ile sonuçlanması yapının daha sağlam ve kompakt hale geldiğinin bir göstergesidir. Sinterleme sıcaklığının artmasıyla ultrasonik hızlardaki değişim tanecik büyümesini iyi geçekleştiğinin kanıtıdır.
