A polymethyltrimethoxysilane (PMTMS)/hydroxyapatite (HA) hybrid coating was successfully fabricated on a magnesium alloy by hydrothermal treatment and immersion method.The microstructure and composition of the coating were characterized by using X-ray dif
In situ Study on the Growth Behavior of Primary Al3Ni Phase in Solidifying Al-Ni Alloy by Synchrotro
The growth behavior of Al3Ni intermetallic compounds (IMCs) during the directional solidification of Al-10 wt% Ni alloy was investigated by synchrotron radiography. Two main growth patterns of primary Al3Ni phase, I-like and V-like, appeared during solidi
Effect of Solution Treatment on the Microstructure and Mechanical Properties of Sand-Cast Mg-9Gd-4Y-
Sand-cast Mg-9Gd-4Y-0.5Zr (wt%) alloy was solution-treated at 500-565 ℃ in the time range of 0.5-30 h in air or vacuum to investigate its microstructure evolution and mechanical properties.The results showed that solution treatment temperature had a signi
The different solution and migration behaviors of tetrahedral and octahedral interstitial helium in bcc iron have been investigated by using first principles calculations.We showed that the tetrahedral site has less charge transfer and less redistribution
The Mg-8Sn-4Zn-2Al (TZA842,in wt%) alloys with different initial microstructure (as-cast-AC and homogenization treatment-HT) subjected to hot extrusion.Also,the strengthening responses to AC and HT for the extruded TZA842 alloys were reported.The results
Effect of Heat Treatment on Microstructure and Mechanical Properties of Quenching and Partitioning S
In order to investigate the effect of microstructural characterization on the mechanical properties and retained austenite stability,a different type of quenching and partitioning steel (I-Q&P) through intercritical annealing before the quenching and part
Spherical Nb-20Si-24Ti-2Cr-2Al pre-alloyed powders were processed by selective laser melting (SLM) on Ti6Al4V substrates with different energy densities.A series of single tracks and single layers were produced using different processing parameters,includ
In order to investigate the microstructure and mechanical property evolution of low-carbon reduced activation ferritic/martensitic (RAFM) steel during isothermal aging,the normalized and tempered specimens were aged at 600 ℃ for 500,1000,and 3000 h,respec
A multi-phase-field model has been developed to simulate the microstructure evolution and kinetics of the austenite static recrystallization (SRX) in a C-Mn steel.In this model,the bulk free energy that coupling the deformation stored energy with a specia
Influence of Island Scanning Strategy on Microstructures and Mechanical Properties of Direct Laser-D
To investigate the influence of island scanning on the microstructures and mechanical properties of direct laser-deposited Ti-6Al-4V structures,two samples are prepared using island scanning and orthogonal successive scanning,respectively.The microstructu
