Corrrosion
This is the term for the deterioration of a metal due to chemical or electrochemical reaction with its environment.
What is corrosion?
This type of defect occurs when an atom from the crystal moves into an interstitial site, leaving behind a vacancy
What is a Frenkel defect?
According to this law, the partial vapor pressure of each component in an ideal solution is proportional to its mole fraction in the liquid phase.
What is Raoult's Law?
This soft material, often used in toys and stress balls, can bounce and stretch but returns to its original shape.
What is rubber?
This property of a crystal describes the periodic arrangement and orientation of atoms in three-dimensional space.
What is crystallographic symmetry?
When a metal atom loses an electron and enters a solution as an ion, this half-reaction occurs.
What is oxidation?
The atomic packing factor (APF) of this common crystal structure is 0.74, representing the most efficient metallic packing.
Whar is face-centered cubic (FCC)?
When a solute is very dilute, its partial pressure is proportional to its concentration — described by this law.
What is Henry's Law?
These tiny particles suspended in a liquid can make a mixture look cloudy, like milk.
What are colloids?
This term describes the specific orientation of planes and directions in a crystal, typically denoted by Miller indices.
What are crystallographic planes and directions (Miller indices)?
This type of corrosion happens when two dissimilar metals are electrically connected in a conductive environment.
What is galvanic corrosion?
In diffusion-controlled processes, the flux of atoms is proportional to the concentration gradient according to this law
What is Ficks's First Law?
This model considers the energetic interactions between unlike neighboring atoms to explain deviations from ideal solution behavior.
What is the quasi-chemical model?
This property describes a material that flows like a liquid but can also resist deformation like a solid, common in ketchup and toothpaste.
What is viscoelasticity?
In the face-centered cubic (FCC) structure, dislocations move most easily along these slip systems.
What are the {111}⟨110⟩ slip systems?
Corrosion that occurs along grain boundaries is called this.
What is intergranular corrosion?
This type of dislocation has a Burgers vector perpendicular to the dislocation line.
What is an edge dislocation?
In a binary phase diagram, the line separating the liquid phase from the two-phase (liquid + solid) region is called this.
What is the liquidus line?
This long-chain molecule makes up plastics and some gels and can entangle to give materials their unique properties.
What are polymers?
This high-angle grain boundary with a mirror-symmetric orientation relationship is commonly observed in FCC metals after deformation or annealing.
What is a twin boundary (or annealing twin)?
This anodic protection method uses a sacrificial anode that corrodes preferntially
What is sacrificial anode protection?
The Hall–Petch relationship shows that decreasing this microstructural feature increases the yield strength of a polycrystalline metal.
What is the grain size?
A system that appears stable but is not at its lowest possible free energy — such as supercooled liquids or retained austenite — is said to be in this state.
What is a metastable state?
This soft material is made of long polymer chains with cross-links that trap liquid, often used in diapers and contact lenses.
What is a hydrogel?
This type of planar defect results from an error in the stacking sequence of close-packed planes.
What is a stacking fault?
