UTyalo-mali olwenziwayo lweMvula Ukwenza lukhuni intsimbi engatyiwayo

Inkcazelo emfutshane:

Material: Imvula iQinisa iStainless Steel 17-4PH, 15-5PH

Inkqubo yokuCasa: Ukwenziwa koTyalo-mali

Ukuze imvula iqiniswe iintsimbi eziqulethwe ngobhedu, ukuqina kweentsimbi zentsimbi kunyuswa ngenxa yemvula yezigaba ezinobhedu oluqinileyo kwimeko yokupholisa ngexesha lokupholisa. Ukuze uthambise ulwakhiwo kunye nokuphucula ukusebenza kokusetyenzwa, iintsimbi ezinjalo zetsimbi zifuna unyango lobushushu besisombululo. Ubushushu besisombululo esiluqilima semvula esenza lukhuni iintsimbi zokujula eziqulathe ubhedu ngokuqhelekileyo yi-900 ℃ ~ 950 ℃. Emva kokupholisa, i-supersaturated-single-phase structure kunye ne-copper mass fraction ye-1.0% ~ 1.5% inokufumaneka.

Injongo ephambili yonyango oluluqilima lwesisombululo sensimbi engenasici kukuchitha i-carbides okanye ezinye izigaba ezinqambileyo kwisisombululo esiqinileyo sokufumana i-supersaturated single-phase structure. Ukugalelwa kwentsimbi engatyiwa yi austenitic, intsimbi ye austenitic manganese kunye nemvula eyenza lukhuni intsimbi engatyiwayo kufuneka ngokubanzi ibe sisisombululo esomeleleyo.

Imvula yeMartensitic eyenza lukhuni intsimbi engatyiwayo ngokubanzi inekhabhoni 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.

Ukuguguleka kwemvula eqinisa intsimbi luhlobo lwentsimbi yealloyi enomxholo wekhabhoni engekho ngaphezulu 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.

Imvula ephantsi kwe-Semi-austenitic yenza lukhuni intsimbi engatyiwayo, oko kukuthi, imvula eguqukayo yenza lukhuni intsimbi engatyiwayo, equlethe ukungabikho 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.

I-Austenitic precipitation iqinisa insimbi engenasici yintsimbi engenasici enesakhiwo esizinzileyo se-austenite 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.
