← TechnologyWhich consequence results when a molten metal's flow rate into a casting mold is insufficient?
A)Formation of cold shuts occurs✓
B)Increased grain size throughout part
C)Elevated surface oxidation develops
D)Liquation cracking becomes substantial
💡 Explanation
Cold shuts occur if the molten metal does not completely fuse because it cools before filling the mold; *planar solidification* prevents complete fusion. Therefore, cold shuts are a risk, rather than the entire part exhibiting large grains because of a high cooling rate throughout.
