Mutengo wepamusoro Fe-b alloy particle FeB 95:5wt High-Entropy Alloys(HEA) Manufacturing

Boron ine huremu hweatomu hwe10.81. Iyo yemagetsi chimiro ndeye 1s2s2p. Kuwanda kwecrystalline boron i2.31g/cm(20°C), ukuwo density yeamorphous boron iri 2.30g/cm(20°C). Kunyungudika 2079 ℃, kuvira poindi 3660 ℃. Iyo equilibrium phase diagram ye boron-iron binary system inoratidzwa muMufananidzo 1. Muchirongwa cheboroferric, pane eutectic point inenge 3.8% boron content, uye eutectic tembiricha i1149℃. Iron neboron zvinoumba maviri epakati makomisheni, Fe2B neFeB, ayo zvakare akagadzikana zvakanyanya pakupisa kwakanyanya. FeB ine mhando mbiri dzekristaro: tembiricha yepamusoro uye yakaderera tembiricha. Kugadzirwa kwemaindasitiri kwesimbi boride (10% ~ 20% B) kunyunguduka tembiricha ye1400 ~ 1550 ℃, iyo density ye5.8 ~ 6.5g/cm

Nhamba yeboron (0.001%) inogona kupeta kuoma kwesimbi. Kuwedzerwa kweinenge 0.003% B kune simbi isina tsvina kunogona kuvandudza mashandiro ayo. Boron ine zvinhu zvekutora manyutroni, izvo zvinogona kutadzisa kana kumisa cheni kuita kweuranium-graphite nuclear reactions. Naizvozvo, simbi ine boron yakakwira (> 1% B) inoshandiswa muindasitiri yesimba reatomu. Boron musimbi yakakandwa inogona kukanganisa graphitization, nekudaro ichiwedzera kudzika kwemuromo. Kana huwandu hweboron hwakawedzerwa hunopfuura 0.01%, mhedzisiro yekudzikamisa carbide iri pachena, saka kusagadzika kwesimbi yakakandwa kunovandudzwa. Iron rolling, boron content 0.02% ~ 0.1%, inogona kuvandudza kuoma kwepamusoro uye kugadzirisa kusimba kwechena. Kuwedzera Borda 0.001% ~ 0.005% kune inogadzika simbi yakakandwa inobatsira pakugadzira inki yespheroidal. Panguva imwecheteyo, inogonawo kuwedzera zvikamu zve graphite uye kuvandudza kugoverwa kwayo. Izvi zvinoita kuti annealing kurapwa. [2]

Iyo iron base, cobalt base uye nickel base poda inoshandiswa kupfapfaidza (welding) ine 0.5% ~ 4.0% boron. Amorphous fe-silicon-boron alloys ane boron, akadai Feg2SisB3, anogona kutsiva oriented silicon simbi kugadzira magetsi anoponesa transformers uye zvimwe midziyo ine yakaderera iron kurasikirwa uye vhoriyamu diki. Ndfeb magineti echigarire akadai seNd2Fe14B uye Nd15Fe77B8 ane zvakanakira remanence yakakwirira, yakakwira coercivity uye yakakwira magineti simba chigadzirwa, izvo zvinhu zvakanaka zvekugadzira zvikamu zvemagineti zvechigarire.
