This study explores the plastic deformation mechanism and microstructural evolution of as-homogenized as-forging Inconel 718 alloy through low temperature slow strain rate hot compression deformation. The stress-strain curves were analyzed by modulating temperature, rate, strain, extreme grain refinement process from cast billets (with abnormally coarse grains) to final sample was revealed. results show that true stress levels are lower during both compression, relative high fast For sample,...
Textured magnesium alloys usually exhibit anisotropic mechanical behavior due to the asymmetric activation of different twinning and slipping modes. This work focuses on <c+a> pyramidal slip responses rolled AZ31 alloy under two loading conditions, compressive tensile along normal direction. Under condition where direction is closely parallel c-axis unit cell, basal slips are prohibited, dislocations then active tend accumulate at grain boundaries form dislocation walls. Meanwhile, these...
In many alloy systems, the segregation and strengthening of solute atoms are caused by mechanical chemical contributions. To uncover origins behaviors Cd, Si, Sc Zr at (001)α-Al//(001)θ' (010)α-Al//(010)θ' interfaces, first-principles calculations were conducted. Results show that contribution primarily dominates oscillatory on Al matrix side. The θ' side mainly governed both tendency Cd interface (or interface) throughout platelets is small strong) because charge accumulation between host...
Isothermal solidification process of pure metal Al was studied by molecular dynamics (MD) simulation using EAM potential. The effects different cooling rates on the isothermal metallic were studied. first subjected to a rapid process, and then it annealing under conditions. mean first-passage times (MFPT) method Johnson-Mehl-Avrami (JMA) law used qualify kinetic processing, nucleation rate, critical nucleus size, Avrami exponent growth grains calculated. Results show that rate size decrease...
Over the past several years, coherent interface strengthening was proposed and has since drawn much attention. Unfortunately, many fabrication techniques are restricted to very small size. Recently, a brand new method of in-situ nanoparticle systematically investigated, which proved be an efficacious way optimize microstructure improve mechanical property by utilizing uniformly dispersed nanoparticles. In this review, we summarized recent related advances in investigated steels Cu alloys,...
In this paper, the research progress on strengthening of copper and alloy is reviewed. The shows that traditional methods are often accompanied by decrease plasticity, there limitations in size, cost, other aspects process. in-situ nanoparticle plasticizing technology proposed recent years can avoid above problems. idea introduced to realize simultaneous enhancement strength ductility as-cast pure tin bronze alloys. effects precipitation iron-rich nanoparticles microstructure, mechanical...
The Nb-V-Ti-N-C system microelements coupling precipitation behavior in high strength naval steel was thermodynamically analyzed. effects of micron/nano particles on the microstructure, mechanical properties, and corrosion resistance were also studied by an situ scanning electron microscopy (SEM) tensile test, transmission (TEM) analysis, electrochemical polarization measurements. results show that solid solution amount Nb, V, Ti, N, or C decreases steels as temperature decreases....
