A sample of cast iron with .35 wt%C is slow cooled from 1500C to room temperature. What is the fraction of proeutectoid Cementite phase in this material?

Respuesta :

Answer:

So the fraction of proeutectoid cementite is 44.3%

Explanation:

Given that

cast iron with 0.35 % wtC and we have to find out fraction of proeutectoid cementite phase when cooled from 1500 C to room temperature.

We know that

Fraction of  proeutectoid cementite phase gievn as

[tex]{w_p}'=\dfrac{{C_o}'-0.022}{0.74}[/tex]

Now by putting the values

[tex]{w_p}'=\dfrac{0.35-0.022}{0.74}[/tex]

[tex]{w_p}'=0.443[/tex]

So the fraction of proeutectoid cementite is 44.3%
