Sharp1 and Jason T. Provines1 Introduction To counter the effects and high maintenance...

... High-hardness, high-carbide powder metallurgy tool steels such as M62 enable the use of ball bearings at extremely high load and stress levels increasing the potential for rolling contact fatigue failure attributed to nonmetallic inclusions. Ever-cleaner steels are sought, but the results have...

... This chapter discusses the corrosion in oil pipelines, which carry a mixture of fluids such as hydrocarbons, water, gases, and other miscellaneous substances that drive the internal deterioration of steel surfaces. The chapter explains in detail the corrosive nature of multiphase flows...

.... The present paper considers specific challenges associated with creep/fatigue in creep strength enhanced ferritic steels such as Grade 91 and Grade 92. creep fatigue steel damage analysis Jonathan Parker1 Reprinted from JAI, Vol. 8, No. 8 doi:10.1520/JAI103888 Available online at www.astm.org/JAI...

... machined (cut) threads of high-strength steel (ASTM A193 B-7 and A354 Grade 8) were exposed to an aggressive aqueous environment containing 8 wt % boiling ammonium nitrate and stressed to about 40 % of the steel's yield strength. In similar testing conditions, bolts that were thread rolled before heat...

... The statistical nature of bearing failures has been studied using Weibull probability statistics for over 50 years. Historically it has been demonstrated that the origin of many bearing failures is the presence of large nondeformable nonmetallic inclusions in the bearing steel. Methods...

... A large amount of data on irradiation creep of face centered cubic (FCC) and body centered cubic (BCC) steels have been analyzed and published by the present authors, but a recent reanalysis of these data have provided further insight into irradiation creep behavior. The present paper looks...

... Experiments were performed in a wear machine especially constructed to simulate the natural in vivo process of wear in a de-bonded metal-cement interface. Four different bone cements were fretted against S-30 stainless steel with mat surface finish. The validation of the metal surfaces...

... This paper provides comparison of initiation toughness values and J R curve data for a series of geometrically scaled compact (CT) and single edge notched bend (SENB) geometry specimens taken from a well characterized A533B-1 pressure vessel steel. The CT specimens (W = 2B) were of thickness B...

Finally, a technique for editing service load histories to remove non-damaging cycles from service load spectra is described. aluminum cycle editing damage elastic modulus fatigue (materials) fatigue limit life prediction non-damaging cycles steel...

... Atmospheric corrosion resistance of 1.0Ni-0.4Cu-Ca-S steels was investigated. The effects of Ca and S on the simulated seaside corrosion resistance of 0.1%C-1.0%Mn-0.4%Cu-1.0%Ni-0.01P-Ca-S steels were examined by CCT (cyclic corrosion test), SVET (scanning vibrating electrode technique...

... Performance testing of coil coated steel sheet products usually involves the measurement of paint creep back from a sheared edge or scribe (ASTM D 1654-92) on samples subjected to accelerated and atmospheric exposure tests. Measurements of paint creep are used for screening paints, pretreatments...

... An alternating current (AC) impedance technique has been applied to the monitoring of corrosion rate in outdoor environments and humidity chambers. A corrosion sensor used for corrosion rate monitoring consisted of a pair of ring and rod of steel electrodes embedded co-axially in epoxy resin...

...), and Fort Sherman, Panama (tropical marine). Among the forty-one materials exposed were four coated steel sheet products: G60 galvanized, G90 galvanized, 55% aluminum-zinc-coated, and Type 2 aluminum-coated. Results are presented for the performance of the coated sheet steels after 21 years. These results...

... Although important properties such as strength, toughness, and weldability can be easily measured in the laboratory, there is no generally accepted laboratory test for determining the atmospheric corrosion resistance of low-alloy weathering steels. Because many years of outdoor testing...

... The result of a previous eight-year atmospheric exposure of steels at seven sites in China showed significant effect of variation of Cu, P, and S content within the allowance in carbon steels and copper-free low-alloy steels in corrosive environments. To verify this phenomenon, steels with 0.035...

... This paper consists or three parts. First, fatigue test data are presented for a tensile specimen with transverse stiffeners, a typical steel bridge detail. The specimens were tested under variable-amplitude fatigue for up to 250,000,000 cycles of loading proportional to the gross vehicle weight...

... Unexpected brittle cracking of welded beam-column connections during the 1994 Northridge earthquake has raised serious concerns about standards and practice for the seismic design and construction of steel moment resisting frames. As part of a nationally coordinated program to investigate...
