MMET 206 Test 1 Questions and Answers | Latest Update | 2024/2025 | 100% Verified What is the significance of the grain structure in metals? The grain structure in metals is significant because it affects mechanical properties such as strength, toughness, and ductility; finer grains often result in stronger materials. How do impurities affect the properties of metals? Impurities can alter the properties of metals by introducing defects in the crystal lattice, which can lead to decr...
