Abstract

Transparent organic analogues were directionally solidified to investigate, via in-situ observation, the peritectic reaction occurring in the YBa{sub 2}Cu{sub 3}O{sub 7{minus}x} YBCO-superconductor system. Nucleation and growth of peritectic and properitectic phases were examined with respect to similarities with the solidification of the YBCO superconductor. The selected organic system, salicylic acid-acetamide, turned out to match the requirements concerning crystal shape, small nucleation rate of the peritectic phase on the properitectic phase, existence of stoichiometric phases with no solubility limits, common and undercooling ability of the peritectic phase. Several features of YBCO growth which were previously deduced only from metallographic cross sections could be verified by direct observation. The organic analogue system will also be used in the future to improve numerical simulations. {copyright} {ital 1997 Materials Research Society.}

Coupled peritectic growth of the {alpha}- and {gamma}-phases in binary titanium aluminides

Book Meissen, F; Busse, P; Laakmann, J

Coupled growth during three phase equilibrium solidification is well known from directionally solidified eutectic systems, and was recently generated in monotectic systems. Several theories predict a stationary peritectic reaction and coupled growth of the properitectic and the peritectic phases therefore should be possible. In spite of these theories coupled growth has not been observed up to now. The TiAl system was selected for further investigation on this topic because of its technical relevance and the fact that it meets the condition mentioned for coupled growth. In a Bridgman laboratory furnace, TiAl with 53.4 at.% Al was directionally solidified with solidificationmore »« less
Coupled growth of the properitectic {alpha}- and the peritectic {gamma}-phases in binary titanium aluminides

Journal Article Busse, P; Meissen, F - Scripta Materialia

Intermetallic compounds are interesting materials for structural, electro-magnetic, chemical or metallurgical applications. They often result from solidification via the peritectic reaction. Because of their low density, high melting point and the resistance in creeping and oxidation, titanium aluminides are most promising high-temperature materials. During isothermal cooling, the properitectic {alpha}-phase solidifies first. At the peritectic temperature, this phase reacts with the melt L and forms the peritectic {gamma}-phase ({alpha}-Ti + L {yields} {gamma}-TiAl). Because the resulting {gamma}-phase envelops the primary {alpha}-phase, further growth of {gamma} is controlled by solid-state-diffusion through the {gamma}-phase. This leads to a relatively coarse microstructure of themore »« less

Effects of Undercooling and Cooling Rate on Peritectic Phase Crystallization Within Ni-Zr Alloy Melt

Journal Article Lü, P. - Metallurgical and Materials Transactions B, Process Metallurgy and Materials Processing Science

The liquid Ni-16.75 at. pct Zr peritectic alloy was substantially undercooled and containerlessly solidified by an electromagnetic levitator and a drop tube. The dependence of the peritectic solidification mode on undercooling was established based on the results of the solidified microstructures, crystal growth velocity, as well as X-ray diffraction patterns. Below a critical undercooling of 124 K, the primary Ni{sub 7}Zr{sub 2} phase preferentially nucleates and grows from the undercooled liquid, which is followed by a peritectic reaction of Ni{sub 7}Zr{sub 2}+L → Ni{sub 5}Zr. The corresponding microstructure is composed of the Ni{sub 7}Zr{sub 2} dendrites, peritectic Ni{sub 5}Zr phase, and inter-dendritic eutectic.more »« less

Grain alignment in bulk YBa[sub 2]Cu[sub 3]O[sub x] superconductors by isothermal peritectic reaction process

Journal Article Lee, Y; Kang, S; Suh, Jeonghun; ... - Journal of the American Ceramic Society; (United States)

An isothermal peritectic reaction (IPR) process has been developed to fabricate YBa[sub 2]Cu[sub 3]O[sub x] (123) superconductors with aligned grain structure in a relatively short time without a temperature gradient. The process consists of the preparation of Y[sub 2]BaCuO[sub 5] (211) powder compact in wire form and infiltration of a Ba-Cu-O glass melt into the 211 compact below the peritectic temperature of [approximately]1010 C. During the infiltration at 965 C the 123 phase forms at the surface of the compact by the reaction between 211 grains and the glass, and the newly formed 123 grains grow directionally towards the centermore »« less
Rapid solidification of undercooled Cu-Ge peritectic alloy

Journal Article Wang, N; Wei, B - Acta Materialia

Bulk samples of Cu-14.4 wt% Ge peritectic alloy has been undercooled by up to 200 K (0.166 T{sub 1}) with a glass fluxing technique. The solidified microstructures are mainly characterized by x-Cu dendrites plus {zeta} phase which forms in the interdendritic areas within the whole undercooling regime. With the increase of undercooling, both the secondary arm spacing of primary x-Cu dendrite and the layer thickness of the peritectic {zeta} phase decrease. The primary trunk and secondary arm of x-Cu dendrites show round shape under small undercooling condition, whereas they keep a good dendritic shape within a large undercooling regime, indicatingmore »« less
