17-4PH	Kunaya kwemvura kwakaoma.	Ndege, zvombo zvenyukireya	Kukwegura (mvura zhinji)

Mafomu Ekurapa Kupisa Kwesimbi Isina Kushanda

1. Kunyungudutsa

Chinangwa:

• Deredza kuomarara uye kuvandudza ductility

• Deredza kushushikana kwemukati

• Gadzirisa chimiro chezviyo

Maitiro:

• Pisa kusvika patembiricha yakatarwa (800–1100°C zvichienderana negiredhi)

• Bata kwenguva yakatarwa

• Tonhorera zvishoma nezvishoma, kazhinji muchoto

Yakashandiswa:

• Ferritic (430)uyemartensitic (410, 420)magiredhi

• Kunyorovesa mushure mekushanda muchitonhora

• Kuvandudza mashandiro emuchina

sakysteelinopa masevhisi ekugadzirisa annealing anodzorwa kuti ive nechokwadi chekuti magadzirirwo emuchina akafanana uye kupfava kwakanyanya pakugadzira.

2. Kugadziriswa kweMhinduro (Kurapwa kweMhinduro)

Chinangwa:

• Nyungudutsa makabhohaidhiretsi uye mvura inonaya

• Dzorerai kuramba ngura

• Kuwana chimiro chakafanana che austenitic

Maitiro:

• Pisa kusvika ~1040–1120°C

• Kudzima nekukurumidza mumvura kana mumhepo kuti chivakwa chiome

Yakashandiswa:

• Simbi dzisina ngura dzeAustenitic(304, 316)

• Zvakakosha mushure mekushongedza kana kupisa

• Inobvisa chromium carbide precipitates uye inodzorera ngura kuramba

sakysteelinoita kuti kunyungudika kwemvura kuitwe nekudzima nekukurumidza kudzivirira kusvibiswa uye ngura pakati pemagranular.

3. Kuomesa (Kudzima)

Chinangwa:

• Wedzera simba nekuomarara

• Kuvandudza kuramba kupfeka

Maitiro:

• Pisa simbi dzisina ngura dzemartensitic kusvika ~950–1050°C

• Bata kuti chivakwa chirambe chakasimba

• Kudzima nekukurumidza mumafuta kana mumhepo

Yakashandiswa:

• Simbi dzisina ngura dzeMartensitic(410, 420, 440C)

• Zvinhu zvinoda kuomarara kwepamusoro (mavharuvhu, mabheyaringi)

Cherechedza: Simbi dzeAustenitic hadzigoni kuomeswa nekupisa.

4. Kudzikisa

Chinangwa:

• Deredza kuputsika mushure mekuoma

• Wedzera kusimba

• Gadzirisa kuomarara zvichienderana nezvinodiwa zvekushandisa

Maitiro:

• Pisa kusvika 150–600°C mushure mekuomesa

• Gara kwemaawa 1-2 zvichienderana nehukuru hwechikamu

• Kutonhorera mumhepo yakanyarara

Yakashandiswa:

• Simbi dzisina ngura dzeMartensitic

• Kazhinji zvinosanganiswa nekuomesa mumatanho maviri

sakysteelinodzora kutenderera kwekudziya kwemhepo zvakanyatsoenderana nezvinodiwa zvemakanika zvebhechi rega rega.

5. Kuoma kwemvura (Kukwegura)

Chinangwa:

• Simbisa kuburikidza nekuumbwa kwakanaka kwe precipitate

• Wana simba guru rekukohwa pasina kukanganisa kwakanyanya

Maitiro:

• Kurapa mhinduro pa ~1040°C uye kudzima

• Zera pa480–620°C kwemaawa akati wandei

Yakashandiswa:

• 17-4PH (UNS S17400)uye ma alloys akafanana

• Zvikamu zvemuchadenga, zvenyukireya, uye zvine simba guru

Mabhenefiti:

• Chiyero chakanaka chesimba nehuremu

• Kudzivirira ngura zvakanaka

• Kukanganisa kudiki kana tichienzanisa nekuomesa martensitic

---

6. Kuderedza Kushushikana

Chinangwa:

• Bvisa kushushikana kwemukati kunokonzerwa nekugadzira, kugadzira, kana kusanganisa

• Dzivisa kuchinja kwehukuru panguva yebasa

Maitiro:

• Pisa kusvika 300–600°C

• Mira kwenguva yakatarwa

• Tonhorera zvishoma nezvishoma

Yakashandiswa:

• Zvikamu zvikuru zvakagadzirwa

• Zvikamu zvakagadzirwa nemazvo

sakysteelinopa mhinduro dzekuderedza kushushikana dzakagadzirwa kuti dzirambe dzakagadzikana pakugadzira zvinhu zvakaoma.

Mhedziso

Kurapa kupisa idanho rakakosha mukugadzirwa kwesimbi isina ngura, zvichibvumira kudzora kwakarurama simba remakanika, kuramba ngura, uye chimiro chemukati. Zvichienderana nealloy uye mashandisirwo ayo, kurapwa kwekupisa kunogona kusanganisira kunama, kurapwa kwemvura, kuoma, kudziya, kuderedza kushushikana, kana kukwegura.

Nekunzwisisamafomu ekurapa kupisa ekugadzira simbi isina ngura, mainjiniya nevatengi vanogona kutsanangura maitiro akakodzera ekushandisa zvakakosha.sakysteel, tinopa mabasa ekugadzira nekupisa anoenderana nezvinodiwa nenyika dzese uye zvinodiwa nevatengi.
