nickel net yes A sort of use widely of Material , use widely , from filter and separation arrive electromagnetic shield and industry process . nickel net of characteristic and performance Instead of grain structure closely related , therefore optimization grain structure by improve performance Very important .
nickel net microscopic structure , Right now grain arrangement Way , deal with matter of method , right That Wholeness able have Decide Qualitative effect , involving mechanical , Electricity and Thermal characteristic . pass fine Adjustment grain structure , theory superior Can Significantly Enhance nickel net Mechanics strength , pass guide efficiency as well as other core Performance .
optimization nickel net grain structure of most often Square Law one yes grain refine . Should process involving reduce Material Inside single grain of size , usually pass Cold working or heat treatment Waited Procedure . pass refine grain structure , Can improve Material of strength and toughness , make That Even Suitable Require harsh of application .
exist fine Adjustment nickel net grain structure process middle , conduct of process middle , one The essential and complex factor manage exist exist right Grain boundaries accurate control . Grain boundaries as adjacent grain between dividing line , right Material Wholeness able have far-reaching Influence . of great importance , Influence too Pass far-reaching ! pass efficient Grain boundaries Control Strategy , Goals of method , were able Significantly promote nickel net Corrosion resistance , Plasticity and other criticality signifier mark , Can imagine this Once passed Procedure not only Require go deep understand material science Fundamental , return need use advanced processing technology and Precision experiment method , Solve the problem of way , by accomplish right Grain boundaries form , density as well as grain between interaction Accurate control .
Apart from grain refine and control Grain boundaries outside , consider Material Inside grain of orientation also Very heavy want . pass make grain along specific direction arrangement , Can Enhance Material of Mechanical behavior , For example Increase stretch strength or improve Anti-fatigue sex .
have Various technology Available At optimization nickel net of grain structure . For example , annealing and re-crystallize Craftsmanship Available At control grain size and orientation , and Grain boundaries project Available At improve Material of Corrosion resistance and Ductility .
In short , optimization nickel net grain structure yes improve That performance of The key factor . pass carefulness control grain size , orientation and boundary , Can improve Material of strength , conductivity and other criticality able . this Can exist widely of application middle improve performance and Durability , make nickel net become right each industry Even have value of Material .
