Imvula yenza lukhuni intsimbi engatyiwayo, ebizwa ngokuba yi-PH Steel, ibhekisa kuhlobo lweyenziwe ngentsimbi eshayinayoeyongeza iintlobo ezahlukeneyo kunye nobuninzi bezinto eziqinisayo, kunye neentlobo ezahlukeneyo kunye nobuninzi be-carbides, i-nitrides, i-carbonitrides kunye ne-intermetallic compounds ziyaqiniswa ngenkqubo yokuqina kwemvula. Imvula yenza lukhuni intsimbi engatyiwayo ayipheleli nje ngokuba namandla aphezulu, kodwa ikwanazo nokuqina okuhle kunye nokumelana nomhlwa. Imvula eyenza lukhuni intsimbi engatyiwayo ingaphoswa apha kuthiisiseko sotyalo-malingokwemizobo yakho, iimfuno kunye nemeko yokusetyenziswa.
Ngokomxholo wezinto eziphambili zealloyi kwimvula eyenza lukhuni intsimbi engatyiwayo kunye nezinto ezongeziweyo zokuqina, imvula enokuqina intsimbi inokwahlulwa ngokweendidi ezine kwezi zilandelayo:
(1)Imvula yeMartensitic Ukwenza lukhuni intsimbi engatyiwayo. Ngokuqhelekileyo iqulethe i-carbon engaphantsi kwe-0.1%. Yomeleza ngokudibanisa izinto ezilukhuni (ubhedu, i-aluminium, i-titanium kunye ne-aluminium, njl.) ukwenza ukungabikho kwamandla. Umxholo we-chromium uphezulu kune-17%, kwaye inani elifanelekileyo le-nickel liyongezwa ukuphucula ukuxhathisa ukubola.
(2)Imvula eMaraging Ukwenza lukhuni intsimbi engatyiwayo, kunye nomxholo wekhabhoni ongekho ngaphezu kwe-0.03% ukuqinisekisa ukuqina, ukuxhathisa kwe-corrosion, i-weldability kunye nokusebenza kwe-matrix ye-martensite, kunye ne-12% ye-chromium yokuqinisekisa ukuxhathisa ukubola. Ukongezelela, i-cobalt ye-alloy element yongezwa ukuqhubela phambili ukuphucula umphumo wokushisa ukushisa kwentsimbi.
(3)iSemi-Austenitic Precipitation Ukwenza lukhuni intsimbi engatyiwayo, oko kukuthi, imvula eguqukayo yenza lukhuni isinyithi esingenasici, equlethe akukho ngaphantsi kwe-12% yechromium. Inomxholo wekhabhoni ephantsi, kunye ne-aluminiyam njengeyona nto iphambili yokuqina kwemvula. Olu hlobo lwemvula eyenza lukhuni intsimbi engatyiwayo inomsebenzi ongcono xa iyonke kunemvula yemartensitic eyenza lukhuni intsimbi engatyiwayo.
(4)iAustenitic Precipitation Ukwenza lukhuni intsimbi engatyiwayoyintsimbi engenasici kunye nesakhiwo se-austenite esizinzile kuzo zombini iindawo ezicinyiweyo kunye nokuguga. Umxholo wayo we-nickel kunye nomxholo we-manganese uphezulu, kwaye umxholo we-chromium uphezulu kune-13% ukuqinisekisa ukuxhathisa okulungileyo kokubola kunye nokumelana ne-oxidation. Kwangaxeshanye, iaustenitic precipitation eyenza lukhuni intsimbi engatyiwayo ihlala yongeza ititanium, ialuminiyam, ivanadium okanye iphosphorus njengezinto eziqina imvula, kwaye yongeza inani elincinci leboron, vanadium, nitrogen kunye nezinye izinto ukufumana iipropathi ezigqwesileyo.
Imvula eyenza lukhuni intsimbi engenasici isetyenziswa kakhulu kumashishini aphambili. Umzekelo, imvula eqhelekileyo eyenza lukhuni intsimbi ye-17-4PH ingasetyenziselwa ukwenza izakhiwo ezingaphantsi kwe-370 ° C ezifuna ukuxhathisa ukubola, ukumelana nokunxiba, kunye namandla aphezulu.
