This specification covers round, square, rectangular, and special shape electric-resistance-welded carbon and alloy steel mechanical tubing produced by hot- or cold-rolling. The types of tubing covered here are: Type 1a, as-welded from hot-rolled steel (with mill scale); Type 1b, as-welded from hot-rolled pickled and…
Metso Corp's board of directors has rejected a revised acquisition proposal from The Weir Group plc.
Significance and Use 4.1 This test method is used to determine the concentration of sulfur in light liquid hydrocarbons, gasoline, and diesels and their additives, where such concentrations of sulfur can be detrimental to their production, performance, an
Abstract Timetal Grade 17 is a high-strength deep hardening forging alloy. This datasheet provides information on composition, physical properties, and tensile properties as well as fracture toughness and creep. It also includes information on forming and heat treating. Filing Code: Ti-154. Producer or source: Timet.
Significance and Use 4.1 This practice is useful as one method of controlling some electroplating solutions. It serves to indicate the presence of contamination or some other adverse condition. 4.2 Ductility measurements are of particular value when elec
Significance and Use 5.1 The thickness of a coating is often critical to its performance. This eddy-current method is nondestructive and is suitable for measuring the thickness of anodic coatings on aluminum, as well as the thickness of most nonconductive
The current density of GaN-based light emitting diode (LED) plays a strong impact on the light output and heat transfer performances. In this paper, the finite element simulation software ANSYS is used to simulate the thermoelectric performance of LED chip with different electrode structures. The conventional LED chip…
A novel porous organic polymer that is being developed by scientists in Saudi Arabia has the potential to provide new technology for carbon capture. Here we look briefly at the work done thus far.
In the present paper, a chip with a Pt-based RTD that functions as a heater and sensor is tested under serial power loads, and infrared (IR) thermal imaging system is adopted to obtain the thermal measurement. Comparisons of the hotspot temperatures of the chip obtained by RTD and IR methods have been made, where diff…
Significance and Use 5.1 This test method is intended to be used when a quantitative measurement of the alkali durability of a ceramic-glass enamel is needed. The test is applicable to glass coated with fired enamels where exposure to strong alkalis, or a
According to Moore's Laws, complexity and power densities of electronic devices are increased during the last decades, moreover their dimensions are shrinking to nanometers causing hot-spot temperature escalation. Thermal management, therefore, becomes a critical issue for next generation of electronics. This scenario…
The corrosion inhibition of S-benzyl o-phenylenedioxydithiophosphate (BPOTP), for carbon steel in hydrochloric acid solution was studied by electrochemical measurements and weight loss measurements. Polarization curves indicate BPOTP is a mixed-type inhibitor, and the effects of temperature, hydrochloric acid concentr…
Welcome to the International Conference on Oxide Materials for Electronic Engineering - fabrication, properties and applications (OMEE-2014) in Lviv, Ukraine, May 26–30, 2014.
Raspberry-like SiO2(R-SiO2) nanoparticles were prepared by electrostatic self-assembly of two different sizes SiO2nanoparticles under the help of polyelectrolytes, which would be removed by further calcination. The R-SiO2/epoxy composites were fabricated then by a solvent-free curing process. The morphology of R-SiO2a…
This specification covers a group of common requirements that, unless covered by the individual product specification in another ASTM document, applies to steel and alloy castings for use in general industrial applications. Materials shall be produced by open-hearth or electric furnace process with or without separate…
This specification covers nominal-wall-thickness, seamless and welded austenitic steel tubing for general corrosion-resisting and low- or high-temperature service. All material shall be furnished in the heat-treated condition. The steel shall conform to the chemical composition requirements. Different mechanical test…
The wettability of coating surface has important significance in the spreading situation of piece of sticky piece, and the welding state of Au-Sn solder. Wettability of solids is expressed with wetting contact angle. In this paper, by studying the wetting angles of the water droplets on the surface of the different ce…
This guide covers standard specification for round, square, rectangular, and special shape, electric-resistance-welded mechanical tubing, either zinc-coated (galvanized) after welding or produced from aluminum-coated, zinc-coated (galvanized), zinc-iron alloy-coated (galvannealed), or aluminum-zinc alloy-coated steel…
Zn-doped talc synthesized under hydrothermal conditions show a strong relation between talc morphology, pH-values and crystallization temperature. These synthetic, well-characterized Zn-doped talc crystals may have potential for possible technological uses in novel applications.
This specification deals with one-wear, two-wear, and multiple-wear wrought carbon steel wheels for locomotives and cars. The classes of steel wheels according to passenger car service covered here are: Class L, which are for high speed services with more severe braking conditions than other classes and light wheel lo…
