Abstract:
The impact of Si levels on electrical conductivity (EC) and hardness in Al-Mg-Si 6xxx aluminum conductor alloys was studied at different aging times. Three experimental alloys with the Si levels of 0.4, 0.66, 0.89 wt.% containing a constant Mg content of 0.65 wt.%, designated as Si4, Si6, and Si9, were selected. It is found that the average peak hardness of Si4, Si6, and Si9 alloys were 114, 127 and 140 HV, respectively. The Si9 alloy with the highest Si level exhibited the highest peak hardness, which was consistent with the number density of strengthening precipitates. However, the EC of all

This article describes the analysis of the polytype transformation of SiC ingot. We analyzed the sample by Raman spectroscopy and TEM observation. The result of the analysis shows the polytype is transformed from 4H-SiC to 6H-SiC, and then returned to 4H-SiC. We found that the direction of the c-axis is not the same as the growth direction of the ingot. And also we found the existence of 8H-SiC at the interface between 6H-SiC and 4H-SiC region by the selected area diffraction pattern and confirmed it by HR-TEM observation.

Silicon carbide is a large band gap semiconductor under development for microelectronic device applications involving high temperatures, high frequencies, and high power. Single crystal thin films of high purity β-SiC can be fabricated by epitaxial CVD onto a <100> silicon wafer substrate. Epitaxial growth is achieved by a two-step process in which the surface of the silicon substrate is first converted to SiC by heating in the presence of hydrocarbon vapors, Despite the large lattice mismatch, this process results in an epitaxial film of β-SiC 10nm in thickness, upon which the SiC cryst

Silicon carbide (SiC) is the generic name for a material which is produced and fabricated by a number of processing routes. One of the three SiC materials investigated at NCSU is Norton Company's NC-430, which is produced by reaction-bonding of Si vapor with a porous SiC host which also contains free C. The Si combines with the free C to form additional SiC and a second phase of free Si. Chemical vapor deposition (CVD) of CH3SiCI3 onto a graphite substrate was employed to produce the second SiC investigated.

Abstract:
Abstract The stress corrosion cracking (SCC) of underaged, peakaged and overaged Al 7010 in either water vapour saturated air (WVSA) or in salt water has been investigated using transmission electron microscopy (TEM). The crack tip and near crack tip regions formed in Double Cantilever Beam (DCB) samples are described. A range of behaviours will be outlined in relation to the observed grain boundary microstructures and it will be shown that fracture is caused by either pure mechanical rupture, pure corrosion or SCC.

Abstract:
Abstract The recently developed retrogression and reaging (RRA) heat treatments have been applied to redress the trade-off between strength and corrosion resistance in 7000 series aluminum alloys. So far they have been applied to thin and small sample sizes with some success. In this study a modified RRA treated material was found to show significant improvement in both the exfoliation and stress corrosion cracking (SCC) resistances, with only a minimal loss in yield strength compared to its T6 temper. Comparative SEM and TEM analyses of their fracture mode were made. A model has been proposed

Abstract:
Abstract Intergranular stress corrosion cracking (SCC) of alloy B-2 (UNS N10665) can occur in dilute acids at low temperatures if there is short range ordering and Ni4Mo in its metallurgical structure. Certain chemistries of alloy B-2 are particularly susceptible to the rapid kinetics of the Ni4Mo transformation, which can occur within minutes of exposure to temperatures of 650-750°C such as during welding. The severity of ordering is dependent on alloy chemistry and thermomechanical processing conditions, and can result in reduced ductility at 700°C, and subsequently to SCC. SCC in the heat-a

Abstract The effect of alloying elements such as titanium or phosphorus, and the effect of PWHT on SCC susceptibility of super martensitic stainless steel welded joints were examined. On the basis of the sensitization mechanism due to the formation of Cr-carbides, the effect of titanium on the SCC susceptibility was determined. It is revealed that the super martensitic stainless steel (0.01C-12Cr-6.5Ni-2.5Mo) without titanium suffered SCC in the specific region of the TTS diagram (Time - Temperature -Sensitization) during the 2nd thermal cycle of the simulation HAZ.

The long-term effects of exposure to sour brines were evaluated using C-ring specimens tested at 400°F (204°C), 500°F (260°C), and 600°F (316°C) for up to 3 years. Microstructures of the C-276 samples were characterized before and after sour brine testing using TEM to evaluate the effects of initial microstructure and of temperature-related changes in microstructure on corrosion and cracking.

Pomimo ogromu regulacji dotyczących żywności, pojęcie „zdrowej żywności” nie jest ujęte w żadne ramy prawne, a jego rozumienie przez społeczeństwo jest niejednolite.

Emigracja jest dla nich deklasacją lub degradacją, gdyż muszą żyć w gorszych warunkach niż te, do których przywykli w swoim kraju.

Abstract:
The pH of solutions found under disbonded polyethylene tape coatings in the field is generally in the range of 6.5 to 7.5. Electrochemically determining corrosion rates for pipeline steels exposed to neutral pH solutions in this pH range indicate that corrosion rates are too low to account for the observed crack growth rates from field excavation programs. This suggests that for the SCC process to be based on a simple dissolution mechanism then the pH at the crack tip would have to be lower than the bulk solution pH.
