    Crystallography is the experimental science of determining the arrangement of atoms in the crystalline solids (see crystal structure).
  • Electrical resistivity and conductivity
    Electrical resistivity (also known as resistivity, specific electrical resistance, or volume resistivity) is an intrinsic property that quantifies how strongly a given material opposes the flow of electric current.
  • Hardness
    Hardness is a measure of how resistant solid matter is to various kinds of permanent shape change when a compressive force is applied.
  • Scanning electron microscope
    A scanning electron microscope (SEM) is a type of electron microscope that produces images of a sample by scanning it with a focused beam of electrons.
  • Shape-memory alloy
    A shape-memory alloy (SMA, smart metal, memory metal, memory alloy, muscle wire, smart alloy) is an alloy that "remembers" its original shape and that when deformed returns to its pre-deformed shape when heated.
  • Sputtering
    Sputtering is a process whereby particles are ejected from a solid target material due to bombardment of the target by energetic particles, particularly, in the laboratory, gas ions.
  • Strength of materials
    Strength of materials, also called mechanics of materials, is a subject which deals with the behavior of solid objects subject to stresses and strains.
  • Transmission electron microscopy
    Transmission electron microscopy (TEM) is a microscopy technique in which a beam of electrons is transmitted through an ultra-thin specimen, interacting with the specimen as it passes through it.
  • Ultimate tensile strength
    Ultimate tensile strength (UTS), often shortened to tensile strength (TS) or ultimate strength, is the capacity of a material or structure to withstand loads tending to elongate, as opposed to compressive strength, which withstands loads tending to reduce size.
  • Cementite
    Cementite, also known as iron carbide, is an intermetallic compound of iron and carbon, more precisely an intermediate transition metal carbide with the formula Fe3C.
  • Hysteresis
    Hysteresis is the time-based dependence of a system's output on present and past inputs.
  • Phase diagram
    A phase diagram in physical chemistry, engineering, mineralogy, and materials science is a type of chart used to show conditions (pressure, temperature, volume, etc.) at which thermodynamically distinct phases occur and coexist at equilibrium.
  • Solid solution
    A solid solution is a solid-state solution of one or more solutes in a solvent.
  • Carburizing
    Carburizing, carburising (chiefly British English), or carburization is a heat treatment process in which iron or steel absorbs carbon while the metal is heated in the presence of a carbon bearing material, such as charcoal or carbon monoxide.
  • Fracture
    A fracture is the separation of an object or material into two or more pieces under the action of stress.
  • Thermal analysis
    Thermal analysis is a branch of materials science where the properties of materials are studied as they change with temperature.
  • Ohmic contact
    An ohmic contact is a non-rectifying electrical junction: a junction between two conductors that has a linear current–voltage (I-V) curve as with Ohm's law.
  • Photoresist
    A photoresist is a light-sensitive material used in several industrial processes, such as photolithography and photoengraving, to form a patterned coating on a surface.
  • Viscoelasticity
    Viscoelasticity is the property of materials that exhibit both viscous and elastic characteristics when undergoing deformation.
  • X-ray crystallography
    X-ray crystallography is a tool used for identifying the atomic and molecular structure of a crystal, in which the crystalline atoms cause a beam of incident X-rays to diffract into many specific directions.
  • Electron mobility
    In solid-state physics, the electron mobility characterizes how quickly an electron can move through a metal or semiconductor, when pulled by an electric field.
  • Nondestructive testing
    Nondestructive testing or Non-destructive testing (NDT) is a wide group of analysis techniques used in science and technology industry to evaluate the properties of a material, component or system without causing damage.
  • Solid-state chemistry
    Solid-state chemistry, also sometimes referred to as materials chemistry, is the study of the synthesis, structure, and properties of solid phase materials, particularly, but not necessarily exclusively of, non-molecular solids.
  • Photoelasticity
    Photoelasticity is a method to determine the stress distribution in a material experimentally.
  • Surface states
    Surface states are electronic states found at the surface of materials.

    Thermal spraying techniques are coating processes in which melted (or heated) materials are sprayed onto a surface.
  • Cermet
    A cermet is a composite material composed of ceramic (cer) and metallic (met) materials.
  • Wear
    Wear is related to interactions between surfaces and specifically the removal and deformation of material on a surface as a result of mechanical action of the opposite surface.

    Cemented carbide is a hard material used extensively in cutting tools for machining, as well as other industrial applications.

    Chrome plating (less commonly chromium plating), often referred to simply as chrome, is a technique of electroplating a thin layer of chromium onto a metal or plastic object.
  • Nitriding
    Nitriding is a heat treating process that diffuses nitrogen into the surface of a metal to create a case-hardened surface.
  • Deformation (engineering)
    In materials science, deformation refers to any changes in the shape or size of an object due to- * an applied force (the deformation energy in this case is transferred through work) or * a change in temperature (the deformation energy in this case is transferred through heat).
  • Segregation (Materials Science)
    In materials science, segregation refers to the enrichment of atoms, ions, or molecules at a microscopic region in a materials system.
  • Bonding in solids
    Solids can be classified according to the nature of the bonding between their atomic or molecular components.
  • Photoelectrochemical process
    Photoelectrochemical processes are processes in photoelectrochemistry; they usually involve transforming light into other forms of energy.
  • Entropic force
    In physics, an entropic force acting in a system is a force resulting from the entire system's thermodynamical tendency to increase its entropy, rather than from a particular underlying microscopic force.
  • Friability
    Friability (pronounced /ˌfraɪəˈbɪlətiː/, "fry-uh-BIL-uh-tee"), the condition of being friable, describes the tendency of a solid substance to break into smaller pieces under duress or contact, especially by rubbing.

    The Max-Planck-Institut für Eisenforschung GmbH (MPIE) is a research institute of the Max Planck Society located in Düsseldorf.
  • Structural integrity and failure
    Structural integrity and failure is an aspect of engineering which deals with the ability of a structure to support a designed load (weight, force, etc...) without breaking, tearing apart, or collapsing, and includes the study of breakage that has previously occurred in order to prevent failures in future designs.
