This study carried out a die soldering test using both H13 and 1045 steel to investigate the different performances of these two substrate materials with regard to die soldering. Aluminum alloys with various amounts of silicon (0, 4.5, and 9 wt.%) were used to investigate the action of silicon in the soldering reaction, with the 0 wt.% material being commercial pure aluminum. Aluminum alloy samples of varying Si content were melted and held at 680oC and both H13 and 1045 steel were dipped for two hours in the melt. After the dipping test, the specimens were air cooled and analyzed using SEM and EPMA. The reaction layer of the H13 steel and the aluminum alloys were composed of Al3Fe (ɵ), Al5Fe2(η) and Al8Fe2Si (τ5) phase. The reaction layer between the 1045 steel and the aluminum melt was composed AlFe (ζ), Al5Fe2 (η), Al3Fe (ɵ), and Al8Fe2Si (τ5). The reaction layer thickness with the H13 substrate increased with the Si content of the aluminum; it deceased with increased Si content with the 1045 steel substrate.

Row Of Fibers

The morphology and composition of the fiber-matrix interface can best be studied by transmission electron microscopy and electron diffraction. For some composites satisfactory samples can be prepared by electropolishing. For others such as aluminum alloy-boron composites ion erosion is necessary.When one wishes to examine a specimen with the electron beam perpendicular to the fiber, preparation is as follows: A 1/8 in. disk is cut from the sample with a cylindrical tool by spark machining. Thin slices, 5 mils thick, containing one row of fibers, are then, spark-machined from the disk. After spark machining, the slice is carefully polished with diamond paste until the row of fibers is exposed on each side, as shown in Figure 1.In the case where examination is desired with the electron beam parallel to the fiber, preparation is as follows: Experimental composites are usually 50 mils or less in thickness so an auxiliary holder is necessary during ion milling and for easy transfer to the electron microscope. This holder is pure aluminum sheet, 3 mils thick.

Abstract Zinc-air batteries (ZABs) are considered a promising energy storage system. A model-based analysis is one of the effective approaches for the study of ZABs. This technique, however, requires reliable discharge data as regards parameter estimation and model validation. This work, therefore, provides the data required for the modeling and simulation of ZABs. Each set of data includes working time, cell voltage, current, capacity, power, energy, and temperature. The data can be divided into three categories: discharge profiles at different constant currents, dynamic behavior at different step changes of discharge current, and dynamic behavior at different random step changes of discharge current. Constant current discharge profile data focus on the evolution of voltage through time. The data of step changes emphasize the dynamic behavior of voltage responding to the change of discharge current. Besides, the data of random step changes are similar to the data of step changes, but the patterns of step changes are random. Such data support the modeling of a zinc-air battery for both theoretical and empirical approaches.

Additional Hardening

This paper studies the cyclic ratcheting for two materials under multiaxial stress state. The two materials are SUS304 austenitic stainless steel and A1070 pure aluminum. The former material is known as a material that gives strong additional hardening and the latter material shows little additional hardening under nonproportional cyclic loading. The ratcheting behavior under 12 stress-strain waveforms was extensively studied using hollow cylinder specimen. Ratcheting strain depended on the material and stress-strain waveform. Anisotropic ratcheting was found in A1070 but isotropic ratcheting was observed in SUS304 steel.
