h$)$ Apply phase rule at this composition in $($f$)$ and comment $(5$P$)$

i$)$ Draw the microstructure of a mechanical solid mixture and atomic structure of a single solid solution existing in the diagram $(5$P$).($Show them$)$

Prepare a composite such that, it will have dual phase in its mirostructure and max. working temperature based on the diagram. $(5$P$).$

A$)$ Devise $($draw$),$ a ternary system $A,B,C$ having $AB,B{C}_2,A_{3}C$ as binary and $A_{2}B{C}_2$ as ternary compounds. Define $1$ ternary eutectic, $1$ peritectic point in this diagram. $(10$P$)$ Use ruler for drawing and be neat in your writing GOOD LUCK.
