Abstract:
In this paper, the scientific and technological efforts will be outlined, which were made during the development of mechanical surface strengthening procedures to improve
the fatigue strength of materials. Excluding particular straining methods, e.g. coining or inhomogeneous plastic deforming, which can also be restricted to well-defined
surface and subsurface areas, three different ways exist in which the fatigue strength can mechanically be effected: Firstly, by machining, secondly, by rolling and
thirdly, by shot peening. These processes are applicable to brittle as well as to ductile materials. Furthermore, they are not restricted to materials with particular
chemical composition or to distinct material states. Moreover, they can be applied to smooth and notched surfaces. In the following, the historical marks in the
development of these three surface strengthening methods will be discussed in more detail up to the end of the 1950's. All data presented were carefully gathered and are
well documented. However, the authors are not quite sure whether or not they overlooked some important documents. In the final chapter of the paper, it will be commented
on some newer contributions to mechanical surface strengthening. Thereby, from the large amount of excellent work achieved by many scientists in the last three decades, for
reasons of space only a few examples can be selected, of course individually. This has been done with full respect to the entirety of investigations which determine the
scientific and technological progress reached in this important field.
