Abstract High total strain-controlled creep-fatigue tests of 1.8% were performed for a directionally-solidified Ni-based superalloy, DZ445, at 900 °C in air. Dwell times of 0, 2, and 5 min. were introduced at the tensile peak strain for each cycle. Experimental results show a decrease in fatigue life with increasing dwell time. The significant cyclic softening is observed after the application of the dwell time. The mean compressive stress and large plastic-strain accumulation are produced due t...

Abstract The mechanical-property improvement of directionally-solidified Nickel-based single crystal (SC) superalloy with the single-direction magnetic fields is limited by their destructiveness on the dendritic microstructure. Here, the work present breaks through the bottleneck. It shows that the application of the cusp magnetic field (CMF) ensures that the dendrites are not destroyed. This feature embodies that the primary dendrite trunks arrange regularly and orderly, as well the secondary d...

Abstract The selective laser melting (SLM) technology is widely used for the manufacturing of Ti6Al4V alloy components in the biomedical and aerospace industries, and the residual pores are one of the significant defects obstructing its further application. X-ray computed tomography (XCT) technique was applied for the examination and analysis of the spatial and morphological features of pore defects, which will influence the tensile properties of the SLM-manufactured Ti6Al4V samples. Hence, the ...

ABSTRACTThe effects of axial static magnetic field (ASMF) on the columnar-to-equiaxed transition (CET) in directionally solidified low carbon steel including peritectic reactions were investigated. Experimental results show that the dendrite morphology of this peritectic steel can be modified under ASMF. The increases of the magnetic field intensity and temperature gradient and the decrease of the growth speed can promote the CET. The columnar dendrites become equiaxed dendrites at a low growth ...

Abstract In this paper, SiO2-based ceramic cores were prepared successfully by the preceramic polymer technique. Effects of sintering temperatures and silicone resin contents on the microstructure and properties of SiO2-based ceramic cores were investigated in N2 atmosphere. Results showed that in N2 atmosphere, the silicone resin transformed into the amorphous SiOC and C-nanowires. SiOC phases mainly adhered on the surface of ball-shaped SiO2 grains and C-nanowires were mainly located in the ga...
