← ScienceWhich outcome occurs when dissolved hydrogen gas exceeds solubility in molten aluminum?
A)Pore formation during solidification occurs✓
B)Increased yield strength in the alloy
C)Enhanced corrosion resistance develops spontaneously
D)Grain size decreases within the metal
💡 Explanation
Pore formation occurs due to hydrogen atoms forming H₂ molecules. Because nucleation sites form, driving gas evolution via bubble formation during solidification, rather than remaining dissolved; therefore, porosity weakens the solidified metal, rather than improving material properties.
