Question
Chapter 9, Problem 9.86P
Interpretation Introduction
Interpretation:
The solubility of hydrogen in liquid aluminum needs to be determined, before solidification and at 0.01 atmospheric pressure.
Concept introduction:
Solidification is a process of forming crystal structure from molten metal during casting.
Degassing is a process of removing hydrogen content from molten metal.
It is necessary to remove hydrogen content from molten metal before casting to improve the quality of the casting.
Amount of gas in molten metal is determined by Sieverts law.
According to Sievert's law,
Percent of gas =
Where K= Content
Pgas = Partial pressure of the gas.
