Microstructure evolution of directionally solidified DZ125 superalloy with melt superheating treatment
TL;DR: In this paper, the microstructure evolution of directionally solidified DZ125 superalloy is systematically investigated by changing the melt superheating temperature, and the results show that the dendrite is refined with the melting temperature increasing from 1500°C to 1650°C.
Journal ArticleDOI
Microstructure and room temperature fracture toughness of directionally solidified NiAl–Mo eutectic in situ composites
TL;DR: In this article, the microstructure and room temperature fracture toughness of pseudo-binary NiAl and Mo in situ composites were investigated, showing that uniform and well-aligned Mo fibrous structures were directionally solidified by the liquid metal cooling process at the growth rate of V = 6μm/s.
Journal ArticleDOI
Effect of power on microstructure and mechanical properties of Ti44Al6Nb1.0Cr2.0V0.15Y0.1B alloy prepared by cold crucible directional solidification
TL;DR: A newly designed alloy Ti 44 Al 6 Nb 10 Cr 20 V 015 Y 01 B ingot was prepared by the cold crucible directional solidification (CCDS) technique under a range of input power with the constant drawing speed of 833μm/s as discussed by the authors.
Journal ArticleDOI
Microstructure and properties of Ni–Ni3Si composites by directional solidification
TL;DR: In this paper, the authors investigated the relationship between solidification microstructure and the properties of Ni-Ni 3 Si in situ composites and showed that the Ni−Ni 3 si hypoeutectic composites have lower micro-hardness than pure Ni 3 Si.
Journal ArticleDOI
Dependency of microstructure parameters and microhardness on the temperature gradient for directionally solidified Ti–49Al alloy
TL;DR: In this article, the authors measured the primary dendritic spacing, interlamellar spacing, and microhardness of a directionally solidified alloy with different temperature gradients.
