An experimental study together with numerical simulation was conducted to investigate the formation mecha-nisms and control methods for stray grains at melt-back of seed in this paper.The numerical simulation results showed that the convex solid/liquid (S
Combination of hot isostatic pressing (HIP) and rejuvenation heat treatment (RHT) technology was used to restore creep-damaged DZ125 directional solidified superalloy,and the influence of microstructure restoration on high temperature fatigue behavior of
CeO2-ZrO2 mixed oxides with controlled morphologies (i.e.,nanorod,nano-polyhedral and disordered shape)were synthesized through either hydrothermal or coprecipitation method,and the corresponding supported Pd/CeO2 ZrO2 catalysts were also prepared by conv
As a candidate material for hydrogen separation,Yb-doped SrCeO3 has attracted increasing attention in recent decades.In the present study,Yb-doped SrCe0.9Yb0.1O3-α ceramics were prepared by the dry pressing and sintering approach,with the microstructure e
The crosslinked gelatin/chitosan/poly(vinyl alcohol)/hydroxyapatite (GEL/CTS/PVA/HAp,GCPH) sponges were fabricated by a freeze-drying method to yield the reinforced composite sponges with proper features.The porosity value and pore size of the crosslinked
The influence of heat treatments on the microstructures and mechanical properties of the selective laser melting manufactured AlSi10Mg alloy modified with Sc was systematically investigated.The results showed that the addition of Sc element introduced pri
Effects of Al addition to a Mg-Sn-Ca ternary alloy on its microstructure and tensile properties after extrusion were studied via extrusion of Mg-1.0Sn-0.5Ca-xAl (x =0,0.8,2.4 wt%) sheets and analysis of the extruded materials.The results showed that Al ad
In this work,Cu/Al8011/Al1060 trilayered composite with an ultrathin copper layer was fabricated successfully by the hybrid process of cast-rolling and hot-roll-bonding.The effects of heat treatment were investigated on the microstructure and mechanical b
