A concept that places emphasis on designed products that lead themselves to easy assembly by robots and other automated equipment. 2. A material that has no fixed composition and contains more than one phase. The components (substances) keep their individual identities. 3. A measure of a material’s resistance to penetration (local plastic deformation) or scratching. 4. A technique produces temperature patterns that can be interpreted to obtain information about the various structural changes that solids undergo as a result of the application of different external forces. 5. A useful tool that is used to study the crystal structures of solids by measuring the angles of electrons glancing off material specimens. 6. An instrument provides magnification of about 2000× and is relatively low-cost. 7. A measure of the attraction between the electron and the nucleus. 8. The energy required to remove a valence electron from an atom. 9. The materials have the structures in which the order of atoms is limited to an atom’s nearest neighboring atoms. 10. A measure of the energy per unit volume that material can absorb without plastic deformation. 11.The method used during design and manufacturing to determine the impact of a product or system on the environment. 12.The ratio of the volume of atoms present in a crystal (unit cell) to the volume of the unit cell. 13.The small particles that occupy the outmost ring or shell from the nucleus, and control the chemical properties of an element. 14.The term implies that a material plastically deforms or flows very slowly under load as a function of time. 15.The term is described by saying that atoms of an element that contain the same number of protons, but different numbers of neutrons
