I-nickel-based wrought superalloys yiklasi yezixhobo zokusebenza eziphezulu ezenzelwe amandla akhethekileyo omatshini, ukuxhathisa kwe-creep, kunye nokuzinza kwesakhiwo kumaqondo okushisa aphakamileyo, ngokuqhelekileyo ngaphezu kwe-540 ° C (1000 ° F). Igama elithi "ukwenziwa" libonisa ukuba ezi alloys zenziwe ngendlela yazo yokugqibela ngokusebenzisa iinkqubo ze-thermomechanical ezifana ne-forging, rolling, okanye i-extrusion, ekhokelela kwi-fine, i-directional grain structure ebonelela ngeempawu eziphezulu kunye nokudinwa xa kuthelekiswa nabalingani babo. Ziyintsika yamacandelo ajikelezayo obushushu obuphezulu kwi-aerospace kunye nokuveliswa kwamandla, apho ukungaphumeleli akuyiyo inketho.

I-nickel-based based corrosion-resistant alloys luhlobo lwemathiriyeli yentsimbi ephucukileyo eyenzelwe ukuba imelane nemekobume edlekayo. Isiseko sabo yi-nickel (Ni) matrix, echasene ngokwemvelo kwizinto ezininzi ezidliwayo, ezixutywe kunye nezinye izinto eziphambili-ngokuyinhloko i-chromium (Cr), i-molybdenum (Mo), kwaye ngamanye amaxesha ubhedu (Cu) kunye ne-nitrogen (N) -ukudala usapho oluguquguqukayo kunye nolunamandla lwezixhobo zezona zinto ziyingozi kakhulu kwiikhemikhali kunye nezicelo zoshishino. Ziyisisombululo xa iintsimbi ezingenastainless zingasanele.

I-iron-based esetyenzisiweyo i-alloys yobushushu obuphezulu yiklasi yezixhobo zetsimbi ezinentsimbi (Fe) njengeyona nto iphambili, eyenzelwe ukugcina amandla omatshini kunye nokuchasana nokuthotywa (njenge-oxidation) kumaqondo okushisa aphakamileyo, ngokuqhelekileyo kuluhlu lwe-540 ° C ukuya kwi-760 ° C (1000 ° F ukuya kwi-1400 ° F). Ukutyunjwa "okwenziwayo" kubonisa ukuba zibunjwe ziinkqubo ze-thermomechanical ezifana nokuqengqeleka okushushu, ukubunjwa, okanye ukukhupha, okucokisa i-microstructure yabo ukubonelela indibaniselwano efanelekileyo yamandla, i-ductility, kunye ne- fabricability. Zisebenza njengesisombululo esingabizi kakhulu kwaye siguquguquka kakhulu kuluhlu olubanzi lwezicelo zobushushu obuphezulu, ukuvala umsantsa wokusebenza phakathi kweentsimbi ezingenasici kunye ne-nickel ebiza kakhulu okanye i-cobalt-based superalloys.

I-cobalt-based superalloys yiklasi yezixhobo zetsimbi ezisebenza kakhulu ezenzelwe ukugcina amandla akhethekileyo omatshini, ukuzinza komphezulu, kunye nokumelana nokubola kumaqondo obushushu aphezulu kakhulu, ahlala edlula lawo apho i-nickel-based superalloys iqala ukuba buthathaka. Zizinto ezisisiseko sembombo kumacandelo abalulekileyo kwezona ndawo zifunwa kakhulu, ngakumbi kwi-aerospace, iiinjini zegesi yemizi-mveliso, kunye nokufakelwa kwezonyango. Ukusebenza kwabo okuphezulu kuphuma kwi-matrix ye-cobalt-chromium eyomeleziweyo kunye nomthamo ophezulu we-carbide particles ezinzima, ezichasayo.
