The heavy 30Cr 2 Ni 4 MoV forging ingots have been extensively used to fabricate the low-pressure rotors, which play a crucial role in the large nuclear power plant. However, the quality of the heavy ingots has been commonly affected by various inner defects. One of the most typical defects is the centerline shrinkage porosity, which has been found to be always accompanied by inclusions...
In this study, Al–10.8Zn–2.8Mg–1.9Cu alloy was synthesized by the spray atomization and deposition technique. The microstructure and mechanical properties of the alloy were studied using optical microscopy, transmission electron microscopy, X-ray diffraction, and tensile tests. The secondary phases in the microstructure of the spray-deposited alloy were examined. The tensile test results indicate...
