Book Description
The fatigue life of 8630 cast steel is studied by employing axial testing. The cast steel specimens are designed with varying levels of porosity and are verified using radiography and microscopy. A qualitative correlation can be made about the fatigue life to the amount/size of porosity that exists in cast steels based on the results.

Book Description
The effect of weld porosity on the fatigue strength of ELI grade Ti-5Al-2.5Sn at cryogenic temperature was determined. A series of high cycle fatigue (HCF) and tensile tests were performed at -320 F on specimens made from welded sheets of the material. All specimens were tested with weld beads intact and some amount of weld offset. Specimens containing porosity and control specimens containing no porosity were tested. Results indicate that for the weld configuration tested, the fatigue life of the material is not affected by the presence of spherical embedded pores. Rogers, P. R. and Lambdin, R. C. and Fox, D. E.

Book Description
This thesis studied a warm-rolling of AISI M-50 steel at 750 C (1382 F). Samples of both warm-rolled and as-received (spheroidized annealed) M-50 were austenitized at 1036 C (1897 F) for various times and subsequently tempered. The heat treated samples were subjected to rolling contact fatigue (RCF) testing. In all cases prior warm-rolling degraded the RCF life at both the L(10) and L(50) levels. Scanning electron microscopy was used to examine the microstructure of the as-received and warm-rolled material between 4000X and 10,000X magnification. It is thought that the increase in the void diameters accounts for the decrease in RCF performance of warm-rolled M-50. The degraded RCF performance is due to both the increase in mean void diameter and the increase in larger sized voids that accompany warm rolling. A qualitative model was developed to account for the origin of voids in as-received material and for the increase in void diameter in warm-rolled material. Keywords: Thermomechanical processing, Residual carbides, Porosity, Void Size Distribution, Bearings, Void Origin Model.
