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 decreased ductility, strength, and corrosion resistance.
What is the difference between elastic and plastic deformation?
✔✔Elastic deformation is reversible and occurs when a material is subjected to stress within its
elastic limit, while plastic deformation is permanent and occurs when stress exceeds the yield
strength.
Describe the term "composite materials" in the context of engineering.
1
,✔✔Composite materials are engineered materials made from two or more constituent materials
with significantly different physical or chemical properties, offering improved strength,
lightweight, and corrosion resistance.
What is the main difference between a metallic material and a polymer?
✔✔The main difference is that metallic materials are typically strong, dense, and good
conductors of heat and electricity, while polymers are usually lighter, more flexible, and can be
insulators.
Describe how corrosion can affect metallic materials.
✔✔Corrosion can lead to the deterioration of metallic materials by chemically reacting with the
environment, resulting in loss of material, reduced structural integrity, and potential failure of
components.
Explain what is meant by "thermal conductivity" in metals.
✔✔Thermal conductivity refers to a metal's ability to conduct heat, which is an important
property for applications involving heat exchangers and thermal management systems.
How does temperature affect the mechanical properties of materials?
2
, ✔✔Temperature can significantly impact the mechanical properties; for instance, increasing
temperature usually decreases strength and increases ductility in metals.
What is the purpose of using a safety factor in engineering design?
✔✔A safety factor is used to provide a margin of safety by accounting for uncertainties in
material properties, loads, and potential flaws in design, ensuring structures can handle
unexpected stresses.
What are the main types of fractures that can occur in metallic materials?
✔✔The main types of fractures are ductile fractures, which involve significant plastic
deformation, and brittle fractures, which occur with little to no deformation, often leading to
sudden failure.
What is the significance of the ductility property in metals?
✔✔Ductility is significant because it indicates how much a metal can deform before breaking,
which is essential for processes like bending or stretching without fracturing.
How does the process of annealing affect metal?
