The Effect of Plasma Spraying on the Microstructure and Aging Kinetics of the Al-Si Matrix Alloy and Al-Si/SiC Composites
Journal of Materials Engineering and Performance, 2010Co-Authors: Yahya Altunpak, Hatem Akbulut, Fatih ÜstelAbstract:The Al-Si (LM 13)-based matrix Alloy reinforced with SiC particles containing 10, 20, and 30 vol.% SiC particles were spray-formed onto Al-Si substrates. The sprayed samples were directly subjected to a standard aging treatment (T551). From the experiments, it was observed that the high rate of solidification resulted in very fine silicon particles which were observed as continuous islands in the matrix and each island exhibited several very fine silicon crystals. Analysis showed that plasma-spraying caused an increased solid solubility of the silicon in the aluminum matrix. DSC measurements in the permanent mold-cast Al-Si matrix Alloy and plasma-sprayed Al-Si matrix Alloy showed that plasma-spraying causes an increase in the amount of GP-zone formation owing to the very high rate solidification after plasma-spraying. In the plasma-sprayed Al-Si/SiC composites GP zones were suppressed, since particle-matrix interfaces act as a sink for vacancies during quenching from high plasma process temperature. Introduction of SiC particles to the Al-Si Age-Hardenable Alloy resulted in a decrease in the time required to reach plateau matrix hardness owing to acceleration of aging kinetics by ceramic SiC particles.

Production and properties of INCOLOY{reg_sign} Alloy 908 tubing for sheathing of Nb{sub 3}Sn superconducting cables
Advances in cryogenic engineering, 1997Co-Authors: J. H. Weber, J. M. PooleAbstract:INCOLOY Alloy 908 is a controlled thermal expansion, Age-Hardenable Alloy developed for Nb{sub 3}Sn cable-in-conduit sheathing applications. It has been specified for the International Thermonuclear Experimental Reactor (ITER) model superconducting magnet coils and is being considered for other similar applications. Overviews of the production sequences for several types of tubing for sheathing are presented. Supporting studies, such as hot ductility, work hardening behavior, and heat treatment responses, used to develop the production schemes are also described. Finally, example properties of the tubing are presented and discussed.
