Heat Treating correct answers Changing the steels microstructure, which alters its mechanical properties such as hardness, strength, ductility, and toughness. Phases: correct answers 1. Ferrite- A soft, ductile BCC phases 2. Austenite- A FCC that can dissolve more carbon Transformation correct answers When steel is heated, it can transform from ferrite -> austenite. Upon cooling it can transform back to ferrite, form carbides or form intermediate phases. Carbon Solubility correct an...

MMET 207 Lab Final Exam Questions and Answers | Latest Version | 2024/2025 | Graded A+ What is the main purpose of metallography in materials testing? Metallography helps analyze the microstructure of metals to determine material properties, such as grain size, phase distribution, and defects. Why is it essential to use mounting and polishing in sample preparation? Mounting and polishing ensure a smooth, even surface that allows for clear microscopic examination of the sample's ...

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...
