  2. Eutectic bonding - Wikipedia

    en.wikipedia.org/wiki/Eutectic_bonding

    Eutectic bonding, also referred to as eutectic soldering, describes a wafer bonding technique with an intermediate metal layer that can produce a eutectic system. Those eutectic metals are alloys that transform directly from solid to liquid state, or vice versa from liquid to solid state, at a specific composition and temperature without ...

  3. Hume-Rothery rules - Wikipedia

    en.wikipedia.org/wiki/Hume-Rothery_rules

    For interstitial solid solutions, the Hume-Rothery Rules are: . Solute atoms should have a smaller radius than 59% of the radius of solvent atoms. [5] [6]The solute and solvent should have similar electronegativity.

  4. Eutectic system - Wikipedia

    en.wikipedia.org/wiki/Eutectic_system

    A eutectic system or eutectic mixture (/ j uː ˈ t ɛ k t ɪ k / yoo-TEK-tik) [1] is a type of a homogeneous mixture that has a melting point lower than those of the constituents. [2] The lowest possible melting point over all of the mixing ratios of the constituents is called the eutectic temperature .

  5. Crystallography - Wikipedia

    en.wikipedia.org/wiki/Crystallography

    Each phase has a characteristic arrangement of atoms. X-ray or neutron diffraction can be used to identify which structures are present in the material, and thus which compounds are present. Crystallography covers the enumeration of the symmetry patterns which can be formed by atoms in a crystal and for this reason is related to group theory

  6. Deep eutectic solvent - Wikipedia

    en.wikipedia.org/wiki/Deep_eutectic_solvent

    Deep eutectic solvents or DESs are solutions of Lewis or Brønsted acids and bases which form a eutectic mixture. [1] Deep eutectic solvents are highly tunable through varying the structure or relative ratio of parent components and thus have a wide variety of potential applications including catalytic, separation, and electrochemical processes.

  7. Lamellar structure - Wikipedia

    en.wikipedia.org/wiki/Lamellar_structure

    A deeper eutectic or more rapid cooling will result in finer lamellae; as the size of an individual lamellum approaches zero, the system will instead retain its high-temperature structure. Two common cases of this include cooling a liquid to form an amorphous solid , and cooling eutectoid austenite to form martensite .

  8. Transient liquid phase diffusion bonding - Wikipedia

    en.wikipedia.org/wiki/Transient_liquid_phase...

    Transient liquid phase diffusion bonding is a process that differs from diffusion bonding. In transient liquid phase diffusion bonding, an element or alloy with a lower melting point in an interlayer diffuses into the lattice and grain boundaries of the substrates at the bonding temperature. Solid state diffusional processes lead to a change of ...
