High Temperature Materials for Exhaust Manifolds

J2515_201712 (Current)

12/20/2017

A subcommittee within SAE ISTC Division 35 has written this report to provide automotive engineers and designers a basic understanding of the design considerations and high temperature material availability for exhaust manifold use. It is hoped that it will constitute a concise reference of the important characteristics of selected cast and wrought ferrous materials available for this application, as well as methods employed for manufacturing. The different types of manifolds used in current engine designs are discussed, along with their range of applicability. Finally, a general description of mechanical, chemical, and thermophysical properties of commonly-used alloys is provided, along with discussions on the importance of such properties.

Nanostructured Ferromagnetic-Wire/Insulator Composites

TBMG-492812/1/2008

A research and development effort now in progress is focused on nano-structured ferromagnetic- wire/insulator composite materials to be used as the magnetic-core materials of sensors for measuring weak magnetic fields. Figure 1 schematically depicts an example of such a sensor — a flux-gate magnetometer that resembles a traditional orthogonal flux-gate magnetometer except that, instead of a single cylindrical ferromagnetic core, there are multiple parallel ferromagnetic wire cores packed together with insulating material between them. An overriding consideration in the design, fabrication, and operation of such a magnetometer is that high effective magnetic permeability of the core is necessary as one of the prerequisites for obtaining high sensitivity.

Gear Materials, Properties, and Manufacture

B-ASM-0139/1/2005

This book is intended for gear metallurgists and materials specialists, manufacturing engineers, lubrication technologists, and analysts concerned with gear failures who seek a better understanding of gear performance and gear life. All of the critical technical aspects of gear materials technology are addressed. Coverage includes an overview of the various types of gears used, important gear terminology, applied stresses and strength requirements associated with gears, and lubrication and wear; in-depth treatment of metallic (ferrous and nonferrous alloys) and plastic gear materials; the properties of carburized steels, the material of choice for high-performance power transmission gearing; and the increasing use of plastics for both motion-carrying and power transmission applications is addressed.

Passive Magnetic Bearings With Ferrofluid Stabilization

TBMG-32114

2/1/1998

Permanent-magnet rotary bearings with ferrofluid stabilization in the axial degree of freedom are undergoing development. These bearings are totally passive, yet stable in all degrees of freedom. In contrast, previously developed electromagnet and permanent-magnet bearings all exhibit instability in at least one degree of freedom, giving rise to the need for active electronic feedback and power-control circuitry. By making active control unnecessary, ferrofluid stabilization can enable reductions in the overall sizes, weights, and power consumptions of machines that contain permanent-magnet bearings. Unlike passive magnetic bearings based on superconductivity, which are restricted to operating temperatures far below room temperature, the developmental bearings are designed to function at temperatures from 0 to 50 °C.
