Abstract:

The early age hardening behavior in Al-Cu-Mg alloys with fixed Cu content (0.50 wt%) and varying amounts of Mg has been studied by hardness tests and TEM observation. Two alloys both exhibit the early rapid hardening phenomenon based on large solute-aggregates analysis. Ageing time of early stage rapid hardening of Al-0.5Cu-1.99Mg alloys is less than that of Al-0.5Cu-1.48Mg alloys. For two alloys, ageing time of early stage rapid age hardening reduces with artificial ageing temperature increasing. The early stage rapid age hardening is depended on the composition and artificial ageing temperat

Abstract:

In the present work, age hardening behavior of CNT reinforced Al6061 and Al2124 nanocomposites, prepared by ball milling and spark plasma sintering, was investigated. The effect of CNT content, annealing time and temperature on the age hardening behavior of the nanocomposites was evaluated and compared to the monolithic alloys prepared and age hardened under the same conditions. It was found that CNTs have a negative influence on the age hardening of the alloys. The alloys displayed standard age hardening behavior i.e. a sharp increase in hardness during initial aging followed by a steady decr

In this study, Al0.5CoCrFe1.5NiTi0.5 high-entropy alloy was heat-treated from 500 °C to 1200 °C for 24 h to investigate age-hardening phenomena and microstructure evolution. The as-cast alloy, with a hardness of HV430, exhibited a dendritic structure comprising an (Fe,Cr)-rich FCC phase and a (Ni,Al,Ti)-rich B2 phase, and the interdendrite exhibited a spinodal decomposed structure comprising an (Fe,Cr)-rich BCC phase and a (Ni,Al,Ti)-rich B2 phase. Age hardening and softening occurred at 500 °C to 800 °C and 900 °C to 1100 °C, respectively. We observed optimal age hardening at 700 °C, and allo

High-energy ball milling and powder metallurgy methods were used to produce a partially alloyed nickel and molybdenum of γ-Ni₃Mo composition (Ni-25at.%Mo). Milled powders were cold-compacted, sintered/solutionized at 1300°C for 100h sintering followed by quenching. Three transformation studies were performed. First, the intermetallic γ-Ni₃Mo was formed from the supersaturated solution at temperatures ranging between 600°C and 900°C for up to 100h. The 100% stable γ-Ni₃Mo phase was formed at 600°C after 100h, while aging at temperatures ranging between 650°C and 850°C for 25h was not sufficient

The concept of hypertensive nephrosclerosis was introduced by Volhard and Fahr in 1914 and has been extensively used in the literature since then, but its existence is controversial. While it is indisputable that malignant hypertension is a cause of end-stage renal disease (ESRD), there remains controversy as to whether the so-called benign nephrosclerosis can also lead to ESRD.Pressure, if it is great enough, will eventually disrupt any structure. Obviously, this is also true of blood pressure. It is therefore not surprising that an experimentally induced great increase in pressure disrupts t

Abstract:

Abstract Several types of very high strength copper nickel alloys are tested with respect to environment sensitive mechanical properties which include hydrogen embrittlement and exposure to sulfide and ammonium compounds. It is found that Cu-Ni-Al-Mn-Nb alloys with nickel content up to 25wt% are resistant to hydrogen embrittlement, sulfide stress corrosion and stress corrosion in ammonium environments, whereas Cu-Ni-Sn materials demonstrate susceptibility to stress corrosion. A study of factors controlling stress corrosion susceptibility of Cu-Ni-Al and Cu-Ni-Al-Mn-Nb alloys shows the principa

Abstract:

Abstract Laser powder bed fusion (LPBF) is becoming a popular additive manufacturing (AM) process for oilfield components of Alloy 718. Despite attracting features, AM 718 is often uneconomical, greatly limited in size, while the build properties differ from wrought counterparts. Among AM processes, wire arc additive manufacturing (WAAM) offers a cost appeal and an improved scalability for Alloy 718. In this investigation, Alloy 718 coupons built by both LPBF and WAAM are compared for their microstructures, mechanical properties, and sulfide-stress cracking (SSC) resistance. To approach the pr

Abstract:

This paper presents a finite-deformation model for extrusion-based layered printing with cementitious materials. The evolution of mechanical properties as the printed material cures and stiffens results in nonphysical reduction in the magnitude of elastic strains when standard constitutive models are employed. This elastic recovery of the printing induced deformation contradicts the experimentally observed behavior of the printed cementitious materials that harden at a nearly-frozen deformed state. A thermodynamically motivated constraint on the evolution of elastic strains is imposed on the c

Abstract:

The application of bio-oils in asphalt and polymer-modified asphalt (PMA), has recently received considerable attention as a pivotal method for enhancing the high-temperature performance of asphalt mixtures while maintaining good binder’s workability. In this study, Jatropha curcas oil (JCO) was selected and evaluated as an PMA modifier. JCO-rHDPE-modified bio-asphalt was prepared with different JCO contents: 1, 3, and 5 wt.%. Physical tests (penetration, softening point, and ductility), rheological tests (dynamic viscosity and rolling thin-film oven test–RTFOT), and thermogravimetric analysis

Abstract:

Micro-alloyed low-carbon linepipe steels offer an advantageous combination of high toughness and a low carbon equivalent (CE or Pcm) for good weldability. The continuing improvements in pipeline steel manufacturing practices have also led to pipeline steels with higher yield to tensile (Y/T) ratios and a corresponding reduction in strain hardening capacity. Potential users of high Y/T ratio pipeline steels are somewhat reluctant to modify their existing specifications. This is because they do not have the required information to judge the performance characteristics of such steels under a wide

Abstract:

This paper aims to present a few aspects of the development of a plastic-hardening macro-element model for steel wires in flexible protection systems. First, the material behaviour is obtained using uniaxial tensile tests. Successively, the evolution of the elastic and plastic domain is obtained using a combination of physical tests, analytical models, and numerical simulations. Finally, the results obtained with the macro-element model are compared to those obtained using other approaches found in literature.

Abstract:

The welding of high strength steels in general, and for pipeline fabrication in particular, has shown that cracking due to hydrogen absorption during welding is more complex in these steels than in older, lower strength steels. In older steels, primary strengthening was accomplished with carbon, which caused hydrogen cracking in the base metal HAZ under reasonably predictable conditions involving microstructure, residual stress and hydrogen level. Pipeline steels were and are in the vanguard of change in strengthening philosophy. The change involves two areas of steel making, chemical composit

Abstract:

Much of the design, construction, and maintenance practices in the pipeline industry was established before the extensive use of modern control-rolled and microalloyed steels. These modern steels can behave differently from traditional hot-rolled and normalized steels. For instance, these modern steels tend to have a lower strain hardening capacity (higher Y/T ratio) than vintage hot-rolled and normalized steels. One of the observed trends is that modern steels could be qualified as higher grade due to the increase of yield strength (YS) while their ultimate tensile strength (UTS) remains at a
