nickel net The reason exist Many kinds industry application middle get widely used , actual use , main benefit exist That excellence Mechanical behavior and Corrosion resistance . Material grain structure right nickel net mechanical strength produce Significantly Influence , right thing of effect , this make go deep understand two By between relation right exist promote nickel net exist filter , Battery electrode , catalytic Convert device and electromagnetic shield wait field performance have arrive close important significance… precise Evaluate Grain size and distributed how Influence nickel net mechanical strength , Shocked . as well as how pass Adjustment Production Process by optimization and promote These characteristic , unique of Attributes , become Got it material science field Form 1 item complex and Tool challenge Task .
exist preparation nickel net process middle , conduct of process middle , pass implement annealing , Cold working and heat treatment wait process , so absolute Can control Metal grain arrangement state , type very many , include grain size , form , orientation as well as distributed pattern , I think These factor Variety move meeting Significantly Influence nickel net Mechanical properties index .
Influence nickel Network machine machinery strength of The key factor one yes grain size . Generally speaking , compare Small of grain size meeting lead to compare high of strength , because compare Small of grain meeting hinder Material Inside Dislocation of sports , thereby make That Even able resistance deformation . grain refine Can pass Cold working wait Craftsmanship Come accomplish , Cold working involving exist low temperature Down make Material deformation by Will grain decomposed into Even Small of size . on the other hand , annealing Can pass general material material heating arrive high temperature and allow grain merge and grow up Come Promote grain grow .
nickel Within the network of grain orientation exist Decide That mechanical strength aspect also rise With crucial of effect . anisotropy Material ( like nickel net ) because grain of arrangement and exist different direction Above table appear different of Mechanical behavior . For example , and vertical direction compared to , have main elongation grain structure of Material exist elongation direction superior have Even high of strength . This kind of anisotropy Can pass rolling or stretch wait Craftsmanship Come design , so that grain along specific direction arrangement , thereby Enhance Material exist Should direction superior of strength and stiffness .
also , Material Inside grain of distributed also meeting Influence That mechanical strength . entire Material middle thin grain of Evenly distributed Can improve strength and toughness , because Grain boundaries of exist meeting hinder Dislocation of sports and Promote deformation process middle of energy dissipation . Improper correct of grain distributed , For example grain of gather or segregation , possible meeting lead to Material Inside Appear weak point , These weak point exist mechanical stress Down easy occur Fault .
In short , nickel net of grain structure right That mechanical strength have major Influence , pass processing technology carefulness manipulate This kind of structure for optimization That exist Various application middle of performance crucial . learn grain size , orientation and distributed how Influence nickel net of Mechanical behavior for develop industrial use high performance Material crucial . pass according to specific of application Require custom made grain structure , engineer and material science Home Can Enhance nickel net exist Various industry application middle of mechanical strength and Wholeness able .
