Question
Chapter 9, Problem 9.112DP
Interpretation Introduction
Interpretation:
The process of accomplishing low residual stresses needs to be designed.
Concept Introduction:
Solidification is a process of forming crystal structure from the molten metal. The time required to solidify the metal completely during casting is the solidification time.
Dendrite size is the distance between a secondary dendrite arm spacing.
Solidification time affects the size of each dendrite.
Secondary dendrite arm spacing reduces at faster solidifications.
