MTL 200 certification (Factors Influencing Solid
Solutions in Metals and Burgers vector)
ASSESSMENT GUIDE
2025|MOST COMMON QUESTIONS WITH
CORRECTLY VERIFIED ANSWERS (the latest
ones)|ALREADY A+ GRADED|GUARANTEED
PASS/wishing you success in your studies
Crystal structure - Same structures needed for solid solubility.
Electronegativity factor - Higher electronegativity increases intermetallic compound
formation.
Valences - Higher valency metals dissolve more readily.
Maximum interstitial impurity - Less than 10% allowed in solid solutions.
Atomic size factor - Atomic radius difference must be less than ±15%.
Interstitial impurity - Impurities occupying interstitial sites in crystal lattice.
Substitutional solid solution - Solute replaces solvent atoms in the lattice.
Lattice distortion - Deformation caused by size mismatch of atoms.
5 rules of Burgers vector - -is the same at all points along the line
-perpendicular to the edge dislocations
-parallel to the screw dislocations
-neither parallel nor parallel perpendicular to mix dislocations.
-Metallic Properties: magnitude of Burgers vectors in a closed packed direction is |b|=|d hkl|
