Answer:
The probable grain-coarsening mechanism is : Ideal grain growth mechanism
( [tex]d^{2}[/tex]- [tex]d_{0} ^{2}[/tex] = kt )
Explanation:
The plot attached below shows the time dependence of the growth of grain.
The probable grain-coarsening mechanism is : Ideal grain growth mechanism
the ideal growth follows this principle = [tex]d^{2} - d^{2} _{0}[/tex] = kt
d = final grain size
[tex]d_{0}[/tex] = initial grain size
k = constant ( temperature dependent )
t = 0
