In this paper, fracture mechanisms under monotonic and cyclic load and its stress distribution of an aluminum cast alloy locally reinforced by SiC particles and Al2O3 whiskers are investigated experimentally and numerically. The material is monotonic

Fractography is the most popular method for failure analysis. This method, however, has been mainly applied to structural steels, and has not been always effective to cast irons. Since many factors like graphite, matrix, cast defects, and so on affec

A numerical analysis of a fracture surface is needed in the fractography. The method proposed in this paper identifies quantitatively the striation region observed in the fatigue fracture surface, and the striated surface ratio is calculated. The met

X-ray diffraction observation of metal fractures provides us with useful information on the mechanisms and mechanical conditions of fracturing. This method has been developed especially as an engineering tool for fracture analysis. (α+γ) dual phase

Nature of the ctitical crack, which triggers hydrogen assisted fracture of the high strength bolt steel ASTM A490 has been studied with an emphasis on the metallurgical observation of the subsurface quasi-cleavage crack. The macroscopic fracture face

Studies have been reported so far with regard to estimation of the stress acted on damaged members in actual machines under a constant load condition using the X-ray fractgraphy technique. However, the load applied on actually used machines and struc

Stress analysis by using fractography is already established technology as means for seeking cause of fracture and has been widely employed. In actually broken machine parts, however, sufficient analytical results may not always be obtained by the te

Uniaxial tension fatigue tests of (α+β) Ti-6Al-4V were carried out in vacuum and air environments to clarify how these environments affect the surface and the interior originating type fatigue properties. Then, the effects of the environments on bo

Residual stress generating in each component phase is formed due to the disturbance strain by interaction between the composition phases as for Fe-Cr steel/TiN system composite prepared by powder metallurgy (P/M). We can obtain macro- and microstress
