Laser Zone-Remelted Alumina-Based Eutectic In Situ Composite
TL;DR: In this paper, the laser zone-remelted Al2O3/YAG/ZrO2 eutectic in situ composite has different microstructure showing fine interpenetrated network with Al 2O3, YAG and ZrO 2 phases continuously intergrown, while none of pores, grain boundaries and amorphous phases is found.
Journal ArticleDOI
The structure between TaC fibers and matrix interface in a Ni, Cr, Al-TaC in situ composite
TL;DR: The Ni, Cr, Al-TaC composite was directionally cast from a nickel-base alloy with a nominal weight composition of Ni-10Cr-50-Al139Ta-09C (wt%) The thermal gradient in the solid-liquid interface was approximately 250 K/cm A withdrawal rate of 5 mum/s was used as discussed by the authors.
Journal ArticleDOI
On real-time control of microstructure of TiAl specimens with varied cross-sections based on numerical calculation and machine learning
TL;DR: In this paper , the authors proposed a real-time adjusted processing method to stabilize the temperature field, which can eliminate equiaxed grain and obviate the occurrence of intergranular fracture during tensile deformation.
Book ChapterDOI
Grain Refinement on Microstructure and Mechanical Properties of IN718 Superalloy
TL;DR: In this article, a mixed refiner of Co3FeNb2 and CrFeNB ternary intermetallic compounds and melt superheating treatment under the modified thermally-controlled solidification (TCS) process have been designed to achieve grain refinement and further improve mechanical properties of IN718 superalloy.
Journal ArticleDOI
Investigation on the Electromagnetic Contactless Shaping and Directional Solidification of Plates of Stainless Steel and Supperalloy under Vacuum
TL;DR: In this article, the authors investigated the distribution of electromagnetic pressure and the coupling between shaping force and temperature field in the electromagnetic contactless shaping process for plates of stainless steel and superalloy.
