reveal nickel net of Grain boundaries
nickel net because of strength , Durability and Corrosion resistance and become Various industry and project application Zhongguang pan- use of Material . However , nickel net of performance meeting receive Material Inside Grain boundaries exist of Significantly Influence . Grain boundaries yes Metal middle each grain between of interface , they right That mechanical and electric performance produce far-reaching of Influence .
learn and reveal nickel net middle of Grain boundaries yes optimization That performance as well as for This kind of Multifunction Material develop new of and Improve of application of The essential step . pass learn Grain boundaries of Location and nature , engineer and Research personnel Can custom made Material of microscopic structure by satisfy specific of need and Require .
reveal nickel net Grain boundaries of The essential method one yes electronic backscatter diffraction ( EBSD ) . EBSD yes A sort of powerful of technology , Can draw Material Inside of crystal orientation and grain boundary . pass use focus Electron beam scanning nickel net sample and analyze reverse scattering electronic , Research personnel Can generate high resolution image , reveal Material middle grain and grain boundary of distributed .
exist through electronic backscatter diffraction〔EBSD〕 technology conduct Material representation hour , the scientist them were able identify Many kinds Grain boundaries type , type very many , include Xiaojiao Spend Grain boundaries , Dajiao Spend Grain boundaries as well as have unique crystallography Attributes special Grain boundaries , Just like dividing line Xiaojiao Spend Grain boundaries feature for grain between exist small orientation difference , abnormal nervous ! and Dajiao Spend Grain boundaries So show Got it Significantly orientation No match , impressive revel . special Grain boundaries not only have unique crystallography characteristic , unique of Attributes , That Physical properties like mechanical and electric characteristic often and specific application Scenes closely related .
reveal nickel net middle of Grain boundaries not only for understand Material of microscopic structure Very heavy want , and for predict That exist Various condition Down of Behavior also Very heavy want . Grain boundaries Can as Dislocation sports of obstacle , Influence Material of deformation Behavior and mechanical strength . they return Can Influence atom of diffusion and Material of electronic characteristic , this make they for catalytic , Sensing and Electronic equipment wait application crucial .
Apart from EBSD outside , Research personnel return use transmission electron microscope (TEM) , X Rays diffraction (XRD) and atomic force microscope (AFM) wait other technology Come Research nickel net middle of Grain boundaries . These method middle of Every A sort of All supply Got it right Grain boundaries nature and feature of unique opinion , helpful comprehensive learn Material of microscopic Structure .
pass reveal nickel net middle of Grain boundaries , Research personnel and engineer Can develop new of Strategy Come improve Material of characteristic and performance . For example , pass control Grain boundaries of distributed and feature , Can improve Material of strength , Ductility and Corrosion resistance , for That exist Require harsh of application middle use open up new Chance .
In short , nickel net Grain boundaries of Research yes material science and project of one important aspect . pass use EBSD wait advanced technology , Research personnel Can reveal Material of complex microscopic structure , and get right That characteristic and Behavior of valuable opinion . Then Can use These Knowledge Come develop innovation of solution , by improve nickel net exist Various application middle of performance and Versatility .
