Cov yam ntxwv tseem ceeb ntawm titanium thiab titanium alloy vuam
High rhiab rau cov pa phem
Qhov chaw vuam yuav hnov mob nrog roj av hauv ib puag ncig thaum nws tshaj 350 degree:
Hydrogen pollution (>300 Degree): Ua rau hydrogen embrittlement
Oxygen pollution (>600 Qib): Tsim ntawm Braintle Oxides
Nitrogen pollution (>700 DEGREE): Ua rau nitrogen embrittlement
Cov yam ntxwv xim ntawm oxide zaj duab xis (ntsuas kub): α Qib-Nyiaj Daj Daj α 600℃α 900 degree: grey tsaus
Thaum cov ntsiab lus carbon yog dhau lawm, tic brittle theem yog tsim
Qhov tseem ceeb theem hloov pauv
Qhov tseem ceeb tshaj plaws ntawm Alpha / Beta theem hloov: 882 degree
Cov yam ntxwv ntawm Cov Cheeb Tsam Cuam Tshuam: ✓ Qhov tseem ceeb coarsening li {}} pegase cov nplej ✓ Kev kub lub sijhawm 3-4 zaug ntawm cov hlau dog dig
Kev tswj cov txheej txheem tsim nyog: → Cov Lus Qhia Kub Kub:<1.5kJ/mm → Cooling rate:>30 Degree / s
Kev Tiv Thaiv nruj yuav tsum muaj
Cov Roj Tiv Thaiv: Argon / Helite Kub: Pib Kub: 200℃Kev Tiv Thaiv Cheeb Tsam Kev nthuav dav: 20-30% nce rau stainless hlau vuam
Nyuaj rau hauv deformation Controlation tswj: Elastic Modulus (110gpa) tsuas yog ib nrab ntawm cov hlau, thiab cov tshuaj tiv thaiv zoo dua lossis sib npaug ntawm 3MPA) thiab tooj liab pads.
Pom tseeb porosity: hydrogen pores account rau ntau dua 70% ntawm tag nrho cov tsis xws luag, thiab nws yog ib qho tsim nyog los tswj cov av noo (<30%) and clean before welding (acetone degreasing).
Cov kev pheej hmoo txaus ntshai: hydrogen inducts cracking yog qhov kev pheej hmoo ntau, xav tau cov ntsiab lus hydrogen ntawm tsawg dua 50ppm hauv cov khoom siv vuam thiab tsawg dua 150 degree.
Cov kev txwv ntawm cov sib npaug
NCO TSEG: Qhov tseeb vuam yuav tsum tau txais cov mem tes TB / T4747, thiab nws raug nquahu kom siv mem tes ua haujlwm (zaus 2-5hz) lossis hluav taws xob nqaj vuam.
