... for widely spaced overloads, due to crack growth delay, could not be uncovered. About ten percent of the fatigue crack surface was striated, the remaining area being occupied by quasistriations and featureless regions. The lowest spacing detected in the direct surface scanning mode of electron microscopy...

Examples of the application of these combination methods are presented that include the tensile and compressive...

... in conjunction with scanning microscopy of the same specimen. Development of high voltage instruments capable of operating at 1 mV or more has broadened the scope of application of electron metallography particularly because of the ability to penetrate significantly thicker specimens than with conventional 100...

... and spacing of particles, variability among portions of the material, general anisotropy, and degree of patternness. Raster scanning devices of either the mechanical or television type are intrinsically capable of easily measuring these six parameters. Provision for each is available in at least one...

.... Instruments are classified according to the mode of scanning employed and some of the design factors involved in an image scanning instrument are discussed. The various measurements and counts currently available are described and their applications are considered. quantitative analysis measurement...
