Fracture and Failure
This failure mechanism occurs when metals react with their environment, leading to material loss, during applied load
Stress Corrosion Cracking (SCC)
Adding this element to steel significantly increases its corrosion resistance by forming a passive oxide layer.
Chromium (Cr)
These are the units for Entropy
J/K
This AM based technique utilizes wire as a feedstock and is similar to a gas-metal arc welding process
Wire Arc Additive Manufacturing (WAAM)
The strength of a material's resistance to localized plastic deformation is measured using this test.
Hardness Testing
Law states a crack in a brittle material will propagate when the energy released by the crack is greater than or equal to the energy required to create new crack surfaces
Griffith Law
This element stabilizes beta phase in Ti-64
Vanadium
Formula for the temperature dependence of a reaction
Arrhenius Equation
This process involves solidifying metal by injecting molten material into a shaped cavity at high velocities (60-100 m/s).
High Pressure Die Casting (HPDC)
In transmission electron microscopy (TEM), this technique is used to determine crystal orientation and defects
Selected area diffraction (SAD)
Brittle fracture occurs in metals (ex/ steels) exposed to low temperatures.

This advanced casting technique uses centrifugal forces to create hollow cylindrical components
Centrifugal Casting
Difference between elastic and inelastic scattering?
The elastic scattering occurs with no change in particle energy; whereas the inelastic scattering occurs with change in energy
Common condition in fracture mechanics where a two-dimensional state of strain occurs when all the shape changes of a material happen on a single plane
Plane strain
Steel family that consists of 2 phases in roughly equal proportions
