Robust Process

ABSTRACTOne of the main driving force for the development of advanced structural materials is weight saving especially in the transportation industry in order to reduce CO2 emission. The utilization of gamma aluminides, as good candidates for aerospace applications, is strongly related to the development of a cost-effective and robust processing route, as far as possible. It is well established that the processing route, i.e. cast, wrought or PM, has a dramatic effect on the microstructure and texture of gamma-TiAl alloys. Therefore, significant microstructural variations through post-heat treatments coupled with compositional modifications can only guarantee a proper balance of desired properties. However, a number of metallurgical factors during the processing steps can contribute to some scattering in properties. This review will highlight several critical process variables in terms of the resulting g-TiAl microstructures. Of primary importance is the as-cast texture which is difficult to control and may contribute to prefer some alternative processing routes to ensure a better repeatability in mechanical results. Some innovative processing techniques for controlling the structure will then be presented. The main point which will be discussed in this paper is whether an approach leading to a robust process would not be at the expense of the high performance of the structural material.

The high efficiencies obtained in a combined gas-turbine/steam-turbine power cycle burning low Btu gas (LBG) make it a potentially attractive alternative to the high sulfur emitting direct coal-fired steam cycle. In the gasification process, much of the bound nitrogen in coal is converted to ammonia in the LBG. This ammonia is largely converted to nitrogen oxides (NOx) in conventional combustors. This paper examines the pressurized bench scale performance of reactors previously demonstrated to produce low NOx emissions in atmospheric laboratory scale experiments. LBG was synthesized in a catalytic reformer and fired in three reactors: a catalytic reactor, a diffusion flame, and a stirred reactor. Effects of scale, pressure, stoichiometry, residence time, and preheat were examined. Lowest NOx emissions were produced in a rich/lean series staged catalytic reactor.

Today, designers of SMT electronics are being asked to achieve more while designing around new technical constraints. Many times these constraints force designers to sacrifice commercial advantages of their designs in order to achieve performance goals or vice-versa. This is made worse when industries and regulations impose restrictions on materials such as lead free, high temperature processing, low-PIM or non-magnetic requirements. Often, the choice comes down to either using high performance components that are expensive and sensitive to processing or robust components that either offer reduced performance or are restricted for use due to material content. This is especially true of surface-mount technology components common to electronics manufacturing where solder processing requirements are found. While typical Ag/Pt thick film conductors are a perfect choice for sensitive applications requiring robust processing, they cannot match processing parameters similar to very high leaching resistant materials like nickel barrier. Since nickel barrier is inherently ferro-resonant, some applications cannot be realized without a new material approach. Components manufactured for use in these sensitive, yet demanding applications have now been produced using an Ultra Leach Resistant (ULR) processing of Ag/Pt thick film. The performance of components produced using this ULR material and process have been evaluated for survivability in solder environments to study the resistance to leaching compared to nickel barrier and traditional “leach resistant” materials available today. The results indicate that it is possible to achieve nickel-barrier-like results without ferro-resonant properties using a “ULR” material and process.
