Time dependent shock temperatures were measured for stainless steel (SS) films in contact with transparent anvils. The anvil/window material was the same as the driver material so that there would be symmetric heat flow from the sample. Inferred Hugoniot temperatures, Th, of 5800-7500K at 232-321GPa are consistent with previous measurements in SS. Temperatures at the fihn-anvil interface (T,), ...

An AlZn4SiPb/steel clad composite was prepared via roll bonding at room temperature. The influence of solution and aging treatment on the structure performance investigated. results show that Al/steel composites exhibited satisfactory interfacial adhesion. Pb aged Al matrix spheroidized uniformly dispersed. uneven transition area with a thickness 30–150 nm observed for sample. Some rod-shaped n...

At present, with the adjustment of the structure of the steel industry, the steel logistics industry is also engaged in integrating. Steel logistics resource integration is an important problem to be solved. Based on previous research on steel logistics resource integration, this paper proposes a new research perspective on steel logistics resources integration: supply-demand network of steel l...

a proposed method for protecting carbon steel and hence reducing iron release in an aqueous solution saturated with h2s is presented in this paper. the method is based on forming a stable and resistant sulfide layer (pyrite, fes2, or pyrrhotite, fe(1-x)s, phase or a mixture of both) on the carbon steel surface. the study on the formation of the sulfide layer was carried out considering the effe...

Ferrous metals include cast iron, steel, and the various steel alloys, The only difference between iron and steel is the carbon content. Cast iron contains more than 2-percent carbon, while steel contains less than 2 percent. An alloy is a substance composed of two or more elements. Therefore, all steels are an alloy of iron and carbon, but the term “alloy steel” normally refers to a steel that...

This paper presents the mechanical properties of high strength structural steel and mild structural steel at elevated temperatures. Mechanical properties of structural steel at elevated temperatures are important for fire resistant design of steel structures. However, current design standards for fire resistance of steel structures are mainly based on the investigation of hot-rolled carbon stee...

The source is covered by a watertight steel cylinder which is fixed inside a 0.65 m long section of ASEA-ATOM type BWR fuel channel. Inside the cylinder there is a 37 GBq Cs pellet fixed to a wagon which can be driven up and down by means of a stepping motor. By moving the source, the repeatability of the geometrical positioning is attained. The amplitude and scanning speed are controlled by a ...

Thermodynamic calculation has been applied to predict the inclusion formation in molten SS400 steel. When the Cerium addition in liquid iron is 70 ppm and the initial Oxygen and Sulphur are both 110 ppm, the formation of oxides containing Cerium would experience the transformation from Ce2O3 to CeO2 and also the formation of sulfides containing Cerium would experience the transformation from Ce...

To elaborate, the reality we evolved for was hunter-gatherer culture. This implies certain powerful abilities, but they may not be manifest in an arbitrarily selected current real task. Manually controlling a glass and steel box moving in a crowd of similar boxes at 70 mph without getting killed is a remarkable skill that most of us can perform pretty well, But this does not mean that it is "na...

A novel multipass photoacoustic cell with five stacked electromechanical films as a microphone has been constructed, tested and characterized. The photoacoustic cell is an open rectangular structure with two steel plates facing each other. The longitudinal acoustic resonances are excited transversely in an optical multipass configuration. A detection limit of 22 ppb (10(-9)) was achieved for fl...
