Much remains to be learned about the impact fatigue of materials owing to the difficulty of impact-fatigue experiments, the complication of impact stress waves, and the different responses of materials to impact stresses. This article reviews the literature on the impact fatigue of matallic materials.

Refractory ceramic coatings are desirable for their physical and chemical natures, which make the coatings suitable for many applications involving wear and corrosion environments. The synthesis of a refractory ceramic coating on a metallic substrate can be achieved using laser surface engineering. In this article, laser surface engineering is demonstrated for the synthesis of a TiB2 coating on plain carbon steel. The predeposited layer of a TiB2-based precursor in an organic vehicle treated with a laser produced a variety of microstructures within the modified surface that are unattainable with conventional coating methods.

A study of the monotonic and cyclic deformation behavior of the recently developed oxide-dispersion-strengthened, nickel-based superalloy PM 1000 was carried out at temperatures up to 1,200°C in air. The influence of grain structure and texture was investigated using two heats with an identical particle microstructure—a )100*-fiber-structured bar material with a grain aspect ratio of ten along the longitudinal direction and a pancake-structured sheet material with a grain aspect ratio of four and a )100*{011}-cube on edge texture. Both creep resistance and lifetime in cyclic deformation depend strongly on texture and weakly on the grain aspect ratio, which determines the fracture path. Instead, lifetime can be predicted on the basis of the different Young’s moduli in the longitudinal and longitudinal-transverse direction, respectively.
