Characterisation of a New Generation of Grain Refiners for the Foundry Industry
نویسندگان
چکیده
There have been a number of studies in recent years relating to the mechanisms of grain refinement, poisoning and fade of Al-Ti-B refiners. In addition there have been several new grain refining products introduced for the foundry sector, such as TiBAlloy and Strobloy, for which studies have also been performed, albeit in a more limited way. The new generation of grain refiners have a number of specific beneficial attributes, which distinguish them from the traditional Al-Ti-B refiners. These benefits are explored by characterising the refiner particle types in terms of composition, size, poisoning tendency and fade characteristics.

Study of the relationship between physical and mental workload with quality of work life of workers in the foundry industry
Introduction: One of the most important factors affecting quality of work-life (QWL) is the workload in the form of mental and physical. The increased workload may reduce the level of performance of workers. Therefore, the present study aimed to evaluate the relation of the mental and physicalworkload with the QWLof workers in the foundry industry. Material and Methods: This cross-sectional st...
متن کاملAluminum and Aluminum Alloys Casting Problems
Aluminum castings have played an integral role in the growth of the aluminum industry since its inception in the late 19th century. The first commercial aluminum products were castings, such as cooking utensils and decorative parts, which exploited the novelty and utility of the new metal. Those early applications rapidly expanded to address the requirements of a wide range of engineering speci...
متن کاملCast Structure and Mechanical Properties of Fine Grained Superalloy K4169 by Addition of Refiners
Grain size and microstructural features of cast superalloy K4169 were investigated under various melting and casting conditions together with the addition of grain refiners. It is found that lowering the pouring temperature and adding refiners to the melt before pouring can lead to grain refinement of matrix and improve the proportion of equiaxed grains. At a conventional pouring temperature of...
متن کاملParadise at a Loss: Estimating Market Power in Hawaiian Gasoline Markets
We present a method for analyzing the exercise of market power in an industry in which each firm produces multiple competing goods. We use the method to study the market power of refiners in Hawaii. These refiners sell in two principal markets: jet fuel, with a buyers consortium, and gasoline, with diffuse buyers. With data from January 1992 through the new millennium, we find significant evide...
متن کاملA NEW GENERATION OF OXYNITRIDE GLASSES CONTAINING FLUORINE
Oxynitride glasses are found as grain boundary phases in silicon nitride ceramics. They are effectively alumino-silicate glasses in which nitrogen substitutes for oxygen in the glass network, and this causes increases in glass transition and softening temperatures, viscosities (by two to three orders of magnitude), elastic moduli and microhardness. Calcium silicate-based glasses containing fluo...
