Effect of nano-fillers on the thermal conductivity of epoxy composites with micro-Al2O3 particles
Zhifang Gao,Lei Zhao +1 more
TL;DR: In this article, the structures, morphologies of synthesized nano-materials were examined by X-ray diffraction (XRD), scanning electron microscope (SEM) and transmission electron microscopy (TEM).
Journal ArticleDOI
Influence of microstructure and elemental partitioning on pitting corrosion resistance of duplex stainless steel welding joints
TL;DR: In this article, the influence of microstructure and elemental partitioning on pitting corrosion resistance of duplex stainless steel joints welded by gas tungsten arc welding (GTAW) and flux-cored arc welding with different shielding gas compositions were studied by optical microscopy, electron backscatter diffraction, scanning electron microscopy (SEM) and electron probe microanalysis.
Journal ArticleDOI
Investigation on microstructure evolution and properties of duplex stainless steel joint multi-pass welded by using different methods
TL;DR: In this paper, the microstructure, impact toughness, and pitting corrosion resistance of duplex stainless steel (DSS) welding joints fabricated by using gas tungsten arc welding (GTAW) and flux-cored arc welding with different shielding gas compositions were investigated.
Journal ArticleDOI
Effects of annealing on the structure and mechanical properties of FeCoCrNi high-entropy alloy fabricated via selective laser melting
TL;DR: In this article, the microstructure, residual stress, and mechanical properties of the as-printed specimen and specimens annealed at 773-1573 K for 2'h were compared.
Journal ArticleDOI
Evaluation of constraint effects on creep crack growth by experimental investigation and numerical simulation
TL;DR: In this article, the effects of constraint induced by crack depth on creep crack behavior of P92 steel was investigated by experimental investigation and numerical simulation, which revealed that the high constraint affected creep crack initiation time and steady creep crack growth rate.
