GH4145 alloy

GH4145 alloy feem ntau yog nickel-raws li high-temperature alloy ntxiv dag zog rau kev laus nrog [Ni3(Al, Ti, Nb)] theem. Nws muaj kev tiv thaiv corrosion zoo thiab oxidation tsis kam qis dua 980 degree, siab zog hauv qab 800 degree, zoo so tsis kam qis dua 540 degree, thiab zoo tsim thiab vuam zog. Cov hlau no feem ntau yog siv los tsim lub dav hlau caij nplooj ntoos hlav thiab kauv springs rau cov tshuab dav hlau uas ua haujlwm qis dua 800 degree thiab xav tau lub zog siab thiab so kom txaus. Nws kuj tseem siv tau los tsim cov khoom xws li turbine blades rau roj turbines. Muaj ntau yam xws li daim hlau, strips, tuav, forgings, rings, xov hlau thiab kav.

GH4145 Superalloy alloy tshuaj muaj pes tsawg leeg:

GH4145 Alloy Mechanical Property:

1. GH4145 (GH145) siab kub alloy txoj kev ua haujlwm:Lub alloy yog ib qho yooj yim rau tsim ntawm forging kub ntawm 1220 thiab 950 degree. Cov cua kub ntawm qhov ingot forging tuaj yeem yog 1200 degree. Yuav kom tau txais cov qauv zoo thiab kev ua tau zoo ntawm qhov kawg forging los yog bar, tom qab forging cua sov kub yuav tsum tau nqa tawm ntawm qhov kub thiab txias. Qhov kawg forging kub yuav tsum tsis txhob qis dua 950 degree. Cov hlau yuav tsum tau muab kho tom qab cov txheej txheem nruj heev.

2. GH4145 (GH145) kub alloy vuam kev ua tau zoo:Cov alloy muaj qhov zoo vuam kev ua tau zoo thiab tuaj yeem siv rau ntau yam vuam, tab sis nws yog ib qho nyuaj rau kev ua fusion vuam ntawm qhov chaw nrog cov hlaws loj, thaum nws muaj kev vuam zoo dua ntawm qhov chaw nrog cov ntu me me thiab nyias daim hlau. Vuam yuav tsum tau ua tom qab annealing los yog daws kev kho mob, thiab kev kho kev ntxhov siab yuav tsum tau ua tom qab vuam, siv 980 degree, moisturizing rau 0.5h los yog 900 degree moisturizing rau 2h. Lub welded los ua ke yog tom qab hnub nyoog kom tau txais lub zog nyob ze ntawm lub siab kho cua sov.

3. Kev kho cua sov txheej txheem ntawm GH4145 (GH145) kub kub alloy qhov chaw:Kev kho cua sov ntawm qhov chaw yuav tsum tau ua nyob rau hauv qhov tsis muaj leej faj tsis muaj leej twg nyob nruab nrab lossis txo qhov cua kom tsis txhob muaj sulfidation. Cov khoom yuav tsum tsis txhob "kub-txias" kev kho mob ntawm 870 thiab 650 degree C. Rau qhov chaw uas muaj qhov sib txuam loj, txhawm rau tiv thaiv cov kab nrib pleb, lawv yuav tsum tau txias hauv huab cua tom qab kev daws teeb meem.

Cov hlau no muaj kev tiv thaiv zoo corrosion thiab creep rupture lub zog nyob rau hauv qhov kub thiab txias ib puag ncig, zoo mechanical zog, thiab yog dav siv. Nws muaj zog txaus thiab corrosion thiab oxidation kuj qis dua 980 degree

1. Tsim cov springs thiab bolts ua haujlwm ntawm qhov kub thiab txias; rotor hniav, impellers thiab lwm yam khoom siv ntawm cov roj turbines;

2. Thrust chambers ntawm foob pob ua ntxaij cav;

3. Rov qab thrust khoom ntawm lub dav hlau;

4. Cov hlab ntsha loj loj;

5. Elastic gas seals, elastic sealing pwm, roj hmab txhua yam hluav taws xob cua sov hniav.
