High Purity Nano Fe Powder yeHigh-Entropy Alloys

Mashandisirwo emaindasitiri esimbi semasimbi ekabhoni akawanda uye anopfuura chero 410 IRONother alloys. Carbon steels alloys esimbi ine kabhoni muzvikamu zvakasiyana, kazhinji inosvika 1.7% kabhoni. Mamwe masimbi zvakare anopinzwa mucarbon steels kuti abudise masimbi akaderera-alloy. Simbi dzakadaro dzinowanzoita nickel uye chromium uye dzinoiswa sesimbi isina tsvina, simbi yemidziyo, uye simbi isingapise kupisa. Asina-simbi simbi alloys senge simbi yakakandwa, simbi yakakandwa, nickel iron uye silicon iron zvakare ine akawanda akakosha maapplication. Kumwe kushandiswa kwakakosha kwesimbi kwakafanana neindasitiri inosimudzira. Inoshandiswa muzvinyorwa zvinokonzeresa muHaber process ye synthesis yeammonia, uye muFischer-Tropsch process yekugadzira peturu yekugadzira.Izvi zvinotevera mimwe mienzaniso yezvishandiso zvakajairika: mishonga, mishonga yezvipembenene, poda metallurgy uye zvichingodaro; seinopisa hydrogen jenareta, gel propellant, combustion activator, catalyst, mvura yekuchenesa adsorbent, sintered active agent, etc; inoshandiswa kugadzira poda metallurgy zvigadzirwa, marudzi ese emakanika zvikamu uye zvigadzirwa zvezvinhu, simende zvigadzirwa zve carbide, nezvimwe; sechinhu chinoderedza pamwe nekushandiswa kwekugadzirwa kwesimbi munyu uye indasitiri yemagetsi; sezvokudya zvinovaka muviri (iron fortifier), yekukandira, kana seanoderedza mumiririri; muindasitiri yemagetsi, poda metallurgy. Iron iminerari inoshandiswa mukusimbisa chikafu inodiwa kudzivirira kupererwa neropa, iyo inoderedza kunyura kwehemoglobin uye nekudaro huwandu hweokisijeni hunounzwa kumatishu. Zvinyorwa zvinosanganisira ferric ammonium sulfate, chloride, fructose, glycerophosphate, nitrate, phosphate, pyrophosphate uye ferrous ammonium sulfate, citrate, sulfate, uye sodium iron edta. iyo ferric fomu (fe3+) isimbi iri munzvimbo yepamusoro-soro yevalence uye iyo ferrous fomu (fe2+) isimbi iri pasi pevalence state. iyo iron sosi haifanirwe kudzima kana kuwedzera kuravira uye inofanira kunge yakagadzikana. iron powders inoburitsa yakaderera discoloration uye rancidity. inoshandiswa kusimbisa hupfu, zvinhu zvakabikwa, pasta, uye zvigadzirwa zvezviyo. Kunyungudutswa kwesimbi kubva musimbi yayo kunoitika muchoto chinoputika umo kabhoni (coke) uye limestone zvinopiswa nesimbi izvo zvinoita kuti simbi iri musimbi ideredzwe uye ichishandurwa simbi yakanyungudutswa, inonzi "simbi yenguruve." Nguruve yakanyunguduka ichine imwe kabhoni nesilicon pamwe chete nekumwe kusvibiswa sezvainounganidza muzasi mechoto ine slag yakanyungudutswa inoyangarara pamusoro pesimbi. Ose ari maviri anodirwa uye anodirwa. Iyi nzira inogona kuenderera mberi sezvo zvimwe zvinongedzo zvinogona kuwedzerwa sezvo simbi uye slag inobviswa kubva pasi pechoto.Iyi fomu yesimbi haibatsiri zvakanyanya pakugadzira zvigadzirwa, zvichipiwa kuti ine brittle uye haina kusimba zvakanyanya.Imwe yekufambira mberi kukuru. mune tekinoroji yekunyungudutsa simbi kwaive kuvandudzwa kweBessemer process naHenry Bessemer (1813-1898). Mukuita uku, mweya wakamanikidzwa kana oxygen inomanikidzwa kuburikidza nesimbi yakanyungudutswa yenguruve kuti iite oxidize (kupisa kunze) kabhoni uye kumwe kusvibiswa. Steelis yakabva yagadzirwa muchoto cheokisijeni chinomanikidzwa, umo kabhoni inonyungudutswa musimbi pakupisa kwakanyanya. Kusiyana kwekuoma uye mamwe maitiro esimbi anogona kuwanikwa nekuwedzera kwealloys uye nekudzima, kudzima kuomesa, uye kupisa simbi. Powder metallurgy (sintering) inzira iyo simbi yeupfu kana mamwe simbi inosanganiswa pamwe pakumanikidzwa kukuru pasina kupisa kwakanyanya. kukodzera mafomu akaumbwa. Iyi nzira inoshandiswa kugadzira homogenous (yunifomu mukati mese) zvikamu zvesimbi. Imwe yeanonyanya kubatsira maitiro esimbi ndeye yakasikwa magineti, iyo inorasikirwa nematembiricha. Magnetism inogona zvakare kuunzwa muzvigadzirwa zvesimbi nemagetsi induction. Magnets ehukuru hwese uye maumbirwo anoshandiswa mumamotor, maatomu anopwanya, maCT scanner, uye TV nemakomputa skrini, toname mashoma ekushandisa. Magineti epamusoro anogona kugadzirwa nekuwedzera zvimwe zvinhu (ona cobalt) kusimbi yemhando yepamusoro. Iron chinhu chakakosha kugadzira hemoglobin muropa, inotakura oksijeni kuenda kumasero emiviri yedu. Izvo zvakakosha zvakare sechinhu chinoteedzera mukudya, kubatsira neoxidation yechikafu kugadzira simba. Tinoda mamirigiramu gumi kusvika gumi nemasere eirone zuva rega rega, sechicherwa chicherwa. Iron inowanikwa muzvigadzirwa zvechiropa nenyama, mazai, magoko, muriwo wemashizha egirinhi, pizi, bhinzi, uye zviyo. Kushaikwa kwesimbi kunogona kukonzera anemia (yakaderera masero matsvuku eropa), kushaya simba, kuneta, musoro, uye kupfupika kwekufema. Yakawandisa iron mukudya inogona kukonzera kukuvara kwechiropa, asi ichi chiitiko chisingawanzo. Simbi yakachena yakanyanya kuwanda murabhoritari uye haiwani kushandiswa kukuru kwemaindasitiri.
