Effect of the porosity on the fracture surface roughness of sintered materials: From anisotropic to isotropic self-affine scaling [PDF]
, 2015 To unravel how the microstructure affects the fracture surface roughness in heterogeneous brittle solids like rocks or ceramics, we characterized the roughness statistics of post-mortem fracture surfaces in home-made materials of adjustable ...

Tensile and fatigue properties of Inconel 718 at cryogenic temperatures [PDF]
, 1969 Tests to determine the tensile and fatigue properties of Inconel 718 at cryogenic temperatures show that the alloy increases in strength at low temperatures, with very little change in toughness. The effect of surface finish and grain size on the fatigue

The effect of microstructure and strength on the fracture toughness of an 18 Ni, 300 grade maraging steel [PDF]
Fractography and metallographic sectioning were used to investigate the influence of microstructure and strength on the fracture toughness (KIc) and fracture mechanism of an 18 Ni, 300 grade maraging steel. Increased yield strength from 1442 to 2070 MN/m

The effect of microstructure on the fracture toughness of titanium alloys [PDF]
The microstructure of the alpha titanium alloy Ti-5Al-2.5Sn and the metastable beta titanium alloy Beta 3 was examined. The material was from normal and extra low interstitial grade plates which were either air-cooled or furnace-cooled from an annealing ...

A fundamental approach to adhesion: Synthesis, surface analysis, thermodynamics and mechanics [PDF]
The effects of composites as adherends was studied. Several other variables were studied by fractography: aluminum powder adhesive filler, fiber glass cloth scrim or adhesive carrier, new adhesives PPQ-413 and LARC-13, and strength-test temperature. When
