Abstract
In this study,it is aimed to produce various composites and reveal their physical properties. Tungsten
carbide (WC) powder and the two of cobalt (Co) and titanium (Ti) powders as binder phase have been
used for the preparation of WC-Co-Ti ceramic-metal composite with powder metallurgy. Two different
ultrasonic non-destructive techniques were employed to measure the mechanical wave velocity in WCCo-Ti composites. The study was performed on various specimens with different WCx
content at the
range from 60 to 80% and Co/Ti content in 3:1, 1:1 and 1:3 groups. The WCx
content in examined
materials was determined using the standard destructive analysis. The Young modulus (E) of the
produced composites and the ultrasonic velocity measured through ultrasonic pulse-echo method and
immersion method. Thermal conductivity of samples has been measured via hot disk method. The
relation between the Young modulus' values with ultrasonic wave velocity, which is obtained through
two different methods and thermal conductivity has been physically examined and the results have been
compared with the literature
