Additive kev tsim khoom: {17-4 ps vs . Cx Hmoov Ua Haujlwm

 

Vim li cas roj-atomized 17-4 p p p dominates aerospace am?
Spheroidal powder (15-45μm) achieves >99 {. 5% ntom tom qab sling {}} uts {}} Cx's $ 350 / kg.

 

Thaum tooj liab-ntxiv cx tau teev?
Rau kev txhaj tshuaj tiv thaiv kev txhaj tshuaj uas yuav tsum muaj 200 w / mong a. Koj siab dua 3x -}

 

Cov hmoov tseem ceeb rau cov yam ntxwv?
Flowerability:<25 s/50g Hall flow
Cov ntsiab lus Oxygen:<300 ppm for 17-4PH, <100 ppm for CX
Satellites:<0.5% by particle count
Rov ua dua tshiab: tsawg dua los yog sib npaug rau 5 siv ua ntej cov khoom siv

 

Kev ua haujlwm tom qab?
Kev nyuaj siab ntxhov siab: 650℃/ 1hr rau 17-4 pH (tiv thaiv back cracking)
Ntsiav: 1,180℃/ 100 MPA / 4HR rau CX (tshem tawm microporosity)
Deg tas: Raws li-ua RA 10μm → machined rau RA 0.8μm

 

Kev Kuaj Mob Li Cas?
Tensile tests at 0°, 45°, 90° to build direction. Fatigue testing >10⁷ Cycles .}}}}}}}}}}}}}}}}}}}}}}}}}}
