<\/p>\nPurdue Al\u00fcminyum Ak\u0131 Ara\u015ft\u0131rma Merkezi, ge\u00e7en ay ara\u015ft\u0131rmac\u0131lar\u0131n al\u00fcminyumun mikro yap\u0131s\u0131n\u0131 de\u011fi\u015ftirerek s\u00fcnekli\u011fi art\u0131rabilen ve paslanmaz \u00e7eli\u011fe e\u015fde\u011fer bir mukavemet sa\u011flayan bir teknoloji geli\u015ftirdiklerini duyurdu.<\/p>\n
Bu teknoloji, \u00e7arp\u0131\u015fma onar\u0131m\u0131 s\u0131ras\u0131nda al\u00fcminyum ala\u015f\u0131mlar\u0131nda ortaya \u00e7\u0131kan sorunlar\u0131 ortadan kald\u0131rmay\u0131 ama\u00e7lamaktad\u0131r. Purdue Malzeme M\u00fchendisli\u011fi Fak\u00fcltesi\u2019nden Profes\u00f6r Xinghang Zhang\u2019\u0131n belirtti\u011fi \u00fczere, ara\u015ft\u0131rmac\u0131lar baz\u0131 hafif al\u00fcminyum ala\u015f\u0131mlar\u0131n\u0131n yumu\u015fakl\u0131\u011f\u0131n\u0131 ve d\u00fc\u015f\u00fck mekanik mukavemetini iyile\u015ftirerek, bu ala\u015f\u0131mlar\u0131n end\u00fcstride daha yayg\u0131n bir \u015fekilde kullan\u0131lmas\u0131n\u0131n \u00f6n\u00fcn\u00fc a\u00e7mak istiyorlar. Ona g\u00f6re, paslanmaz \u00e7elikler kadar mukavemetli, y\u00fcksek mukavemetli ve hafif al\u00fcminyum ala\u015f\u0131mlar\u0131, otomotiv ve havac\u0131l\u0131k end\u00fcstrilerinde devrim yaratacakt\u0131r.<\/p>\n
O, bu s\u00fcrecin ticari olarak piyasaya sunuldu\u011funda, al\u00fcminyum kapaklar\u0131 OEM\u2019ler i\u00e7in halihaz\u0131rda beklendi\u011finden daha da cazip hale getirebilece\u011fine inan\u0131yor.<\/p>\n
Purdue\u2019ya g\u00f6re, bir metalin kristal kafesi tekrarlanan atom katmanlar\u0131ndan olu\u015fur; bilim insanlar\u0131 eksik katmanlara \u201ckatmanlama kusuru\u201d, katmanlama kusurlar\u0131ndan olu\u015fan \u00e7ift katmanlara ise \u201cikiz s\u0131n\u0131rlar\u0131\u201d ad\u0131n\u0131 verir. Bak\u0131r ve g\u00fcm\u00fc\u015f katmanlama kusurlar\u0131na yatk\u0131n olsa da, al\u00fcminyumun daha y\u00fcksek katmanlama kusuru enerjisi, bunlar\u0131n yapay olarak olu\u015fturulmas\u0131n\u0131 zorla\u015ft\u0131r\u0131r.<\/p>\n
Purdue ara\u015ft\u0131rma ekibi, al\u00fcminyum ala\u015f\u0131mlar\u0131nda mukavemet ve s\u00fcneklili\u011fi art\u0131rman\u0131n ve termal kararl\u0131l\u0131\u011f\u0131 iyile\u015ftirmenin yolunu buldu.<\/p>\n
Sonu\u00e7lar, paslanmaz \u00e7eliklerle e\u015fde\u011fer veya onlardan daha dayan\u0131kl\u0131 al\u00fcminyum ala\u015f\u0131mlar\u0131n\u0131n nas\u0131l \u00fcretilebilece\u011fini ortaya koyuyor. Zhang yapt\u0131\u011f\u0131 a\u00e7\u0131klamada, \u201cBu bulgunun ticari a\u00e7\u0131dan b\u00fcy\u00fck bir etkisi olabilir\u201d dedi.<\/p>\n

Al\u00fcminyum eriyik maddesi \u00fcreticisi olarak ADTECH, metalurjik malzeme \u00fcretimine odaklanmaya devam eden ve International Enterprise\u2019\u0131n izinden giden \u00f6nc\u00fclerden biridir.<\/p>\n
AdTech\u2019in ar\u0131tma ak\u0131s\u0131, \u00fcr\u00fcnlerin ara\u015ft\u0131r\u0131lmas\u0131, geli\u015ftirilmesi ve yap\u0131land\u0131r\u0131lmas\u0131nda erimi\u015f metalin kar\u0131\u015ft\u0131r\u0131lmas\u0131 ve birle\u015ftirilmesi ilkesini temel al\u0131r. Duman ve tozu azalt\u0131r, yanma at\u0131klar\u0131n\u0131 d\u00fc\u015f\u00fcr\u00fcr ve \u00e7evreyi ekonomik bir \u015fekilde korur.<\/p>\n
Ar\u0131tma ak\u0131s\u0131, b\u00fcy\u00fck miktarlarda hammadde kullan\u0131m\u0131 ve k\u00fcl \u00e7\u0131k\u0131\u015f\u0131 gibi geleneksel ar\u0131tma sorunlar\u0131n\u0131 ortadan kald\u0131r\u0131r. AdTech\u2019in ar\u0131tma katk\u0131 maddeleri ton ba\u015f\u0131na 1,5-2,0 kg olup, k\u00fcl \u00e7\u0131k\u0131\u015f\u0131 0,8-1%'dir; bu, y\u00fcksek hassasiyetli al\u00fcminyum ala\u015f\u0131ml\u0131 d\u00f6k\u00fcm gereksinimlerini kar\u015f\u0131lar, erimi\u015f metal verimini 0,6-0,8% oran\u0131nda etkili bir \u015fekilde art\u0131r\u0131r ve enerji tasarrufu amac\u0131na ula\u015f\u0131r.<\/p>\n
Ar\u0131tma ak\u0131s\u0131, uygun \u0131s\u0131l i\u015flem ve eleme i\u015flemlerinden sonra boyut bak\u0131m\u0131ndan homojen hale gelir; bu da, ar\u0131tma tank\u0131ndaki al\u00fcminyumun N\u2082 veya Ar gaz\u0131 ta\u015f\u0131y\u0131c\u0131 olarak kullan\u0131larak erimi\u015f al\u00fcminyumun alt tabakas\u0131na aktar\u0131lmas\u0131n\u0131 kolayla\u015ft\u0131r\u0131r ve b\u00f6ylece geleneksel t\u0131kanma sorununu tamamen ortadan kald\u0131rarak d\u00f6k\u00fcm kalitesini garanti eder.<\/p>","protected":false},"excerpt":{"rendered":"
