Question

Estimate the maximum expected thermal conductivity for a Cermet that contains 58 vol% titanium carbide (TiC) particles in a cobalt matrix. Assume thermal conductivities of 27 and 69 W/m-K for TiC and Co respectively.

Answer 1

The right answer is "36.32 W/mk".

Step-by-step explanation:

According to the question,

TiC = 76%

or,

= 0.76

CO = 24%

or,

= 0.24

Thermal conductivity of TiC,

= 26 W/mk

Thermal conductivity of CO,

= 69 W/mk

On applying the rule, we get

⇒

On putting the given values, we get

⇒
`=(26)(0.76)+(69)(0.24)`

⇒
`=19.76+16.56`

⇒
`=36.32 \ W/mk`
