Ucoceko oluPhezulu lweNano Fe Powder ye-High-Entropy Alloys

Ukusetyenziswa kwimizi-mveliso yentsimbi njengentsimbi yekhabhoni zininzi kwaye zodlula naziphi na ii-410 IRONother alloys. Iintsimbi zekhabhoni zi-alloys zentsimbi equkethe i-carbon ngomlinganiselo ohlukeneyo, ngokuqhelekileyo ukuya kwi-1.7% yekhabhoni. Ezinye iintsimbi nazo zifakwe kwiintsimbi zekhabhoni ukuvelisa iintsimbi ezisezantsi. Iintsimbi ezinjalo zihlala ziyi-nickel kunye ne-chromium kwaye zihlelwa njengensimbi engenasici, izixhobo zentsimbi, kunye neentsimbi ezikwazi ukumelana nobushushu. I-alloys yentsimbi engeyiyo intsimbi efana nentsimbi ekhandiweyo, intsimbi ekhandiweyo, intsimbi yenickel kunye ne-silicon iron nazo zinemisebenzi emininzi ebalulekileyo. Olunye usetyenziso olubalulekileyo lwentsimbi lusebenza njenge-industrial catalyst. Isetyenziswe kwiingqungquthela ze-catalyst kwinkqubo ye-Haber yokwenziwa kwe-ammonia, kunye nenkqubo ye-Fischer-Tropsch yokuvelisa i-petroli yokwenziwa.Oku kulandelayo yimizekelo yezicelo eziqhelekileyo: amayeza, i-pesticides, i-powder metallurgy kunye nokunye; njengejenereyitha ye-hydrogen eshushu, i-gel propellant, i-activator yokutshisa, i-catalyst, i-adsorbent yokucoca amanzi, i-agent esebenzayo e-sintered, njl. njenge-arhente yokunciphisa ngokunjalo nokusetyenziswa ukwenza ityuwa yentsimbi kunye neshishini lombane; njengezongezo zesondlo (i-iron fortifier), yokuphosa, okanye njenge-arhente yokunciphisa; kwishishini le-elektroniki, i-powder metallurgy. I-iron yiminerali esetyenziswa ekuqiniseni ukutya okuyimfuneko ekuthinteleni i-anemia, enciphisa ukugxila kwe-hemoglobin kwaye ngaloo ndlela isixa seoksijini esiziswa kwizicubu. imithombo iquka iferric ammonium sulfate, chloride, fructose, glycerophos- phate, nitrate, phosphate, pyrophosphate kunye neferrous ammonium sulfate, citrate, sulfate, kunye ne-sodium iron edta. ifom ye-ferric (fe3 +) yintsimbi kwindawo ephezulu ye-valence kunye nefom ye-ferrous (fe2 +) yintsimbi kwi-valence state ephantsi. umthombo wentsimbi kufuneka ungatshintshi okanye wongeze incasa kwaye kufuneka uzinze. umgubo wentsimbi uvelisa umbala ophantsi kunye nerancidity. isetyenziselwa ukuqinisa umgubo, izinto ezibhakiweyo, ipasta, kunye neemveliso zeesiriyeli. Ukunyibilikiswa kwentsimbi kwintsimbi ekrwada yayo kwenzeka kwiziko eliqhumayo apho ikhabhoni (coke) kunye nelitye elikrwada zifudunyezwa ngentsimbi ekrwada nto leyo ekhokelela ekuncitshisweni kwentsimbi ekrwada kuze kuguqulwe intsimbi enyibilikisiweyo, ebizwa ngokuba “yintsimbi yehagu.” Intsimbi yehagu enyibilikisiweyo isenayo ikhabhoni kunye nesilicon kunye nobunye ukungcola njengoko iqokelela emazantsi eziko kunye ne-slag etyhidiweyo edada phezu kwentsimbi. Zombini ziyacolwa kwaye zikhutshiwe. Le nkqubo inokuqhubekeka ekubeni i-moreingredients inokongezwa njengoko intsimbi kunye ne-slag zisuswa ezantsi kwe-furnace.Le fomu yentsimbi ayiloncedo kakhulu kwimveliso yokuvelisa, ngenxa yokuba i-brittle kwaye ayinamandla kakhulu.Enye yenkqubela phambili enkulu. kwitekhnoloji yokunyibilikisa isinyithi yayiluphuhliso lwenkqubo yeBessemer nguHenry Bessemer (1813-1898). Kule nkqubo, umoya ocinezelweyo okanye i-oxygen inyanzeliswa ngentsimbi yehagu enyibilikisiweyo ukuze i-oxidize (itshise) ikhabhoni kunye nobunye ukungcola. I-Steelis emva koko yaveliswa kwisithando somlilo se-oksijini, apho ikhabhoni inyibilika kwintsimbi kumaqondo obushushu aphezulu kakhulu. Iiyantlukwano zobulukhuni kunye nezinye iimpawu zentsimbi zinokufezekiswa ngokudityaniswa kwealloyi kunye nokuqhobosha, ukucima ukuqina, kunye nokushushumbisa isinyithi. Umgubo wesinyithi (i-sintering) yinkqubo apho intsimbi engumgubo okanye ezinye iintsimbi zidityaniswa kunye kuxinzelelo oluphezulu ngaphandle kobushushu obuphezulu ukuya. zilungele iifom ezibunjiweyo. Le nkqubo isetyenziselwa ukuvelisa i-homogenous (uniform kuyo yonke) iindawo zentsimbi.Enye yezona mpawu ziluncedo zentsimbi yimagnetism yendalo, elahlekelwa ngubushushu obuphezulu. I-Magnetism ingangeniswa kwiimveliso zentsimbi ngokufakwa kombane. Iimagnethi zabo bonke ubukhulu kunye neemilo zisetyenziswa kwiinjini, kwi-athom smasher, i-CT scanner, kunye ne-TV kunye nezikrini zekhompyutha, ukubiza ukusetyenziswa okumbalwa. Iimagnethi ezinkulu zinokubunjwa ngokongeza ezinye izinto (bona icobalt) kwi-iron ekumgangatho ophezulu. Intsimbi yinto ebalulekileyo eyenza i-hemoglobin egazini, ehambisa ioksijeni kwiiseli zemizimba yethu. Kukwabaluleke kakhulu njengento elandelwayo ekutyeni, inceda nge-oxidation yokutya ukuvelisa amandla. Sifuna malunga ne-10 ukuya kwi-18 milligrams ye-irone ngosuku, njengeminerali. I-iron ifumaneka kwimveliso yesibindi kunye nenyama, amaqanda, i-shellfish, imifuno enamagqabi aluhlaza, iiertyisi, iimbotyi, kunye neengqolowa ezipheleleyo. Ukunqongophala kwe-iron kunokubangela i-anemia (inani eliphantsi leeseli ezibomvu zegazi), ubuthathaka, ukudinwa, intloko ebuhlungu, kunye nokuphefumla nzima. I-iron eyongezelelweyo kwi-diet ingabangela umonakalo wesibindi, kodwa le yimeko enqabileyo. Intsimbi esulungekileyo iyinto eninzi yaselabhoratri kwaye ayifumani kusetyenziswa kakhulu kwimizi-mveliso.
