Title: A Practical Approach To Preform Design For Different Materials

Abstract

To forge an H-shaped cross section, various preform designs have been tested for steel 42CrMo4, aluminum 7075 and nickel base alloy 80 A (Bohler L306). The influence of different boundary conditions like temperature and friction on the preform and hence on the forming process have been investigated by means of two dimensional finite element analyses. Furthermore, the influence of the preform on the microstructure was computed and the structural damage evolution in the forged parts depending on the preform design has been considered for alloy 80 A.

  • Coining is a forging process in which a metallic disk, characterized by a low volume-surface ratio, is deformed with the aim to impress 3D images on its three surfaces. Due to the large production volumes and, at the same time, to the high quality standards required to the final products in terms of final dimensions, tolerances and surface finishing, such closed-die, cold forging process requires a careful evaluation and choice of the proper operative parameters. In particular, along with technological parameters as the die velocity, die stroke and lubrication, which, in turn, contribute to affect the pressure values on themore » die surfaces, and thus the press choice, geometrical parameters as the side ring inner diameter and, above all, the preform geometry, strongly affect the quality of the obtained parts. In this paper, a 3D FEM model for coining processes is proposed, that is Lagrangian implicit, rigid-viscoplastic. The relationships between the obtained geometry and the starting preform shape is numerically investigated, allowing, through the analysis of the effective stresses, strain, and strain rate on the coin, as well as of the loads on the dies, to highlight the significance of the perform design in order to obtain a final product that satisfies the strict geometrical tolerances required. It is found that the best results on the final part are obtained with chamfered preform geometries, though larger values of force on the dies are observed.« less
  • This paper reports on large variable-frequency drives which are ideally suited to many petrochemical applications. The major concern often expressed during the early stages of the project that could utilize such a drive is that harmonic problems could arise. Numerous papers have been written concerning the sources of these harmonics and locating them in an existing system. An attempt to show how to eliminate the harmonic problems early in the design phase of a project is mad to reassure the uninitiated that the task is not insurmountable.
  • Resurgent interest in electric vehicles has resulted in extensive research and development programs, including government support, to develop a lead-acid battery system which can deliver acceptable range and cycle life. In the last decade, significant gains in energy density, power density, and cycle life have been made. The Improved State of the Art (ISOA) Electric Vehicle (EV) battery developed by the Globe Battery Division of Johnson Controls, Inc., utilizes the leading edge technology responsible for these improvements. The patented electrolyte circulation system is the cornerstone of this design. Emphasis was placed on a systems design approach which included priority considerationmore » for safety and ease of maintenance. Efforts toward achieving the ambitious ''Advanced Battery'' goals are progressing. Rival exotic energy storage systems require considerable additional development before they might become practical alternatives. The major advantages of the lead-acid system firmly position it as the most practical energy source for electric vehicles, both now and in the near future.« less
  • Modern surface science techniques have been commonly applied to understand issues arising from practical catalytic systems.[1-4] However, the applicability of most of the results obtained from model systems has been limited, due, primarily, to the vastly different conditions studies on model and practical systems are carried out (catalyst composition, reaction conditions etc.).[5, 6] Therefore, the need to conduct experiments on compositionally similar systems (model and practical) is necessary to obtain valuable information on the workings of real catalysts. In this communication we demonstrate the utility of surface science studies on model catalysts in understanding the properties of high surface area,more » BaO-based NO x storage-reduction (NSR) catalysts.[7] We present evidence for the facile formation of surface barium aluminate-like species even at very low coverages of BaO. This Ba-aluminate layer, however, can react with NO 2 resulting in the formation of a bulk-like Ba(NO 3) 2 phase. In order to construct model catalysts that are representative of the practical NO x storage systems, we first needed to estimate the BaO covareges on the high surface area catalysts. Since the publication of the work by Fanson et al.[8], BaO loadings of 8 – 10 wt.% on a γ-alumina support (200 m 2/g) have been regarded as corresponding to one monolayer (ML) coverage, based on the unit cell size of bulk BaO. The coverage equivalent of one ML, however, was significantly underestimated. Assuming complete spreading of the BaO layer and using a Ba–O distance of ~ 2.77 Å (one unit of BaO occupies 1.53 × 10 -19 m 2), 10 wt.% loading of BaO would cover only about 1/3 of the alumina surface. Table 1 shows our calculated estimates of two-dimensional BaO coverages as a function of loading on a -Al 2O 3 surface (200 m 2/g) based on the lattice parameters of bulk BaO[9] (5.54 Å). Based on these values, for our model system studies we prepared BaO/Al 2O 3/NiAl(110) materials in which the BaO coverages were very close to those of 4, 8, and 20 wt.% BaO/γ-Al 2O 3 high surface area catalysts used in prior studies.« less
  • The flow behavior of an AlSi10Mg alloy melt in Saffil chopped fiber preforms during liquid metal infiltration aided by squeeze pressure or vacuum has been visualized. Experimental results indicate that under the external pressure the flow behavior of the melt in non-wetting chopped fiber preforms is dominated by capillary laws and the geometrical characteristics of the interspaces in the preform in a manner analogous to flow in a capillary tube network. The degree of saturation of the interspaces is dominated by local infiltration pressure, and variation of the saturation degree at a given infiltration depth is determined by fiber distributionmore » uniformity at the microscopic level.« less
