MatSci Midterm Exam 1 2022/2023
MatSci Midterm Exam 1 2022/2023 4 types of point defects - ANS-Vacancy, self-Interstitial, Impurity Interstitial, Substitutional Impurity Vacancy - ANS-as heat increases, there start to be move empty spots Creep - ANS-things deform over time self-Interstitial - ANS-atoms squeezed in between other atoms in the material Impurity Interstitial - ANS-atoms from another element enter the structure of another element (An example is carbon occupying the space between iron atoms) Substitutional impurity - ANS-similar to impurity interstitial Linear Defects (Dislocations) - ANS-one-dimensional defects around which atoms are misaligned (plastic deformation) edge dislocation - ANS--extra half plane of atoms inserted in a crystal structure -b perpendicular to dislocation line screw dislocation - ANS-spiral planar ramp resulting from shear deformation - b parallel to dislocation line.
