Grain Boundary Diffusion

Famous quotes containing the words grain and/or boundary:

    He showed me that the lines of a good helve
    Were native to the grain before the knife
    Expressed them, and its curves were no false curves
    Put on it from without.
    Robert Frost (1874–1963)

    If you meet a sectary, or a hostile partisan, never recognize the dividing lines; but meet on what common ground remains,—if only that the sun shines, and the rain rains for both; the area will widen very fast, and ere you know it the boundary mountains, on which the eye had fastened, have melted into air.
    Ralph Waldo Emerson (1803–1882)
