nickel net yes A sort of Multifunction Material , Available At Various industry application , include filter , Screening and electromagnetic shield . nickel net of characteristic , For example mechanical strength , conductivity and Corrosion resistance , right That exist These application middle of performance crucial .
Influence nickel net performance of important factor one yes Material of grain size . grain size yes refer to constitute Material structure of single crystal or grain of size . At once nickel In terms of , grain size Can from Several nanometer arrive a few microns , specific depending on manufacture Craftsmanship and heat treatment .
” grain size right nickel net mechanical and corrosive able exist Significantly Influence” this one thesis exist2019 Year《 material science and project : A》 Magazine superior publish Research middle get Got it verify , show grain size Variety change meeting direct Influence nickel net Mechanics characteristic and Corrosion resistance .
Research Discover , nickel net middle of grain size cross Small , mechanical strength and hardness cross high . This is because compare Small of grain supply Got it More of Grain boundaries , Grain boundaries act as Dislocation sports of obstacle and Enhance Material of anti- deformation ability . on the other hand , Discover Larger of grain size meeting lead to mechanical strength compare Low , but Ductility compare high .
exist Corrosion resistance aspect , Research show compare Small of grain size and Corrosion resistance of improve related . This is because More of Grain boundaries for corrosive penetration Material create Got it Even tortuous of path , thereby Enhance Got it That anti- degradation sex .
exist2020 Year 《 alloy and compound Magazine》 superior release one item Research middle , the scientist them Discuss Got it nickel net electricity guide Rate Instead of grain size between relation , Close cooperation , mutual benefit common win , reveal Got it one complex Phenomenon : when grain size Variety Hour , nickel net electricity guide Rate instead Significantly promote . this one result behind Come principle lies in , exist Some party noodle , compare Small grain size guide To Material internal Grain boundaries increase Quite a few , and then Enhance Got it electronic exist Grain boundaries at scattering effect , finally promote Got it overall electricity guide Rate .
exist Quite a few Dimensions analyze later , existing Academic Research reveal Got it grain size and nickel net performance between complex relation : small grain Significantly Hoist machinery strength , hardness , Corrosion resistance and guide Electricity , and Thick grain So favorable exist improve Material Ductility , Can imagine this One shot now right nickel net exist All kinds industry Scenes preparation and application have deep influence . of great importance , Influence too Pass far-reaching !
Looking to the future , need further of Research Come completely reveal control nickel net grain size and performance between relation of potential mechanism . also , explore advanced of manufacture technology Come control and manipulate nickel net of grain size possible meeting lead to develop against specific application have Reinforcement able of custom made Material . finally , right This kind of relation of Deeper enter learn Can for nickel net performance of optimization and technology ability of progress Pave the way .
