Chapter 9, Problem 9.39P

Interpretation Introduction

Interpretation:

The temperature at which nickel casting nucleation takes place needs to be determined. Note that 28 % solidification of nickel casting is through dendritic manner.

Concept introduction:

Dendritic solidification occurs due to lack of nucleating agent in a liquid material which is used to convert the liquid into solid. In dendritic solidification, such liquid is undercooled at temperature uptoa freezing point.
