Download or read book Rapid Solidification and Consolidation of Iron Base Alloys written by R. G. Bourdeau and published by . This book was released on 1986 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rapidly solidified powders of iron base and steel compositions were produced and consolidated for the Massachusetts Institute of Technology (MIT) for use on a companion ONR program. A total of seven compositions were converted to rapidly solidified powder in a P & W experimental rotary atomization device. The powders were screened, canned in extrusion containers, extruded to bar stock and delivered to MIT. Manganese containing TRIP steels and an iron base alloy were produced with refined structures where the contaminants in the steel such as sulfides were finely dispersed. Lanthanum added to the alloy steel gettered the phosphorus and refined phosphides as well as oxysulfides were produced for grain coarsening resistance. The latter steel is being evaluated in sharp-crack k sub IC toughness and k sub ISCC stress corrosion resistance. In addition, Fe-Ni base compositions were produced which are being used to study the effect rapid solidification in as solidified material.

Available in PDF, EPUB and Kindle. Book excerpt: The response of iron-base alloys to rapid solidification is reviewed with an emphasis on the effects of processing on the microstructure and mechanical property behavior. The processing topics addressed are powder atomization, powder consolidation, joining, and thermal-mechanical exposure. The value of rapid solidification processing (RSP) lies in the ability to promote compositional homogeneity and retention of fine and stable (to high temperatures) microstructures. Achieving the maximum benefit from RSP requires proper application of the basic principles of composition control and rapid crystallization. This investigation has disclosed two very important facets of the RSP approach that can be applied using current technologies. Dissociated oxygen appears to play a significant role in stabilizing microstructural features. In conjunction with oxygen, vacancies trapped during crystallization provide a very stable matrix dispersion for enhanced strengthening. With a fundamental understanding of the response of iron-base alloys to RSP, alloys can be designed that will have substantially better properties and performance than their conventionally processed counterparts. 77 refs., 94 figs., 14 tabs.

This book was released on 1991 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: The properties and performance of metallic alloys for heat resistant applications depend on the fineness, homogeneity, and stability of their microstructures, particularly after high temperature exposures. Potential advantages of rapid solidification processing (RSP) of alloys for such applications are the homogeneity in composition and fine microstructural features derived from the nature of the RSP process. The main RSP product form is powder, is which obtained by atomizing a narrow melt stream into fine molten droplets. Rapid cooling of the droplets is typically achieved through convective cooling with noble gases such as argon or helium. Consolidation of RSP powder, either using near-net-shape methods or into forms that can be converted to final product shapes, requires exposures to fairly high temperatures, usually 900 to 1200°C for iron- and nickel-base alloys. Full consolidation, i.e., complete densification with accompanying particle bonding, usually requires pressure or stress assistance. Consolidation, as well as any subsequent thermal-mechanical processing, may affect the chemical homogeneity and fine microstructures. A study has been performed on a series of RSP iron- and nickel-base alloys. The results of microstructure examinations and mechanical properties tests of the consolidated powders, and their correlation, will be covered in this paper. 14 refs., 10 figs., 1 tab.

Book excerpt: Treatise on Materials Science and Technology, Volume 20: Ultrarapid Quenching of Liquid Alloys investigates the relationship between the science and utility of materials, with emphasis on the ultrarapid quenching of liquid alloys. Topics covered range from rapid solidification of non-metals and crystalline iron-base alloys to corrosion behavior of amorphous alloys. Experimental methods in rapid quenching from the melt are also discussed. This volume is comprised of nine chapters and begins with a historical overview of various methods that have evolved for producing rapidly solidified materials. The criteria for the formation of highly metastable states and how these relate to experiment are described. Subsequent chapters explore rapid solidification of non-metals; the industrial implications of rapid solidification of iron-based alloys by means of plasma spraying; annealing effects in metallic glasses; and the corrosion behavior of amorphous alloys. The mechanical properties of metallic glasses are also considered, along with the electrical properties of rapidly solidified materials.
