Ductile deformation - Study guides, Class notes & Summaries

MMET 207 Exam 1 Questions and Answers | Latest Version | 2024/2025 | Rated A+ What is the primary purpose of metallography in material science? Metallography is used to analyze the microstructure of metals, which helps in understanding their properties and performance under various conditions. What effect does strain rate have on the ductility of metals? Increasing the strain rate generally decreases the ductility of metals, leading to more brittle behavior during deformation. I...

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...

Fracture is a type of material failure. Of the following which is another type of material failure? - Answer-Permanent deformation. Which of the following statements best differentiates between a defect and a discontinuity? - Answer-Discontinuities can propagate and become defects. Nondestructive testing is often differentiated from other measurements or inspection techniques in that: - Answer-NDT involves indirect tests related to some other quality or characteristic of material. What are...

What is the description of damage of a brittle fracture? Sudden rapid fracture under stress (residual or applied) where material exhibits little or no evidence of ductility or plastic deformation What type of Steel are of primary concern with brittle fractures? Carbon and low alloy steels. 400 series SS are also susceptible What has a significant influence on toughness and resistance to brittle fractures? Steel cleanliness and grain size In most cases brittle fractures occur only at what t...
