Hauv qhov tseem ceeb ntawm aerospace propulsion systems thiab roj turbine Cheebtsam, qhov kev puas tsuaj feem ntau "stealth killer" yog siab -cycle fatigue (HCF). Rau cov engineers nyob rau hauv aerospace thiab nuclear industries, ib tug loj mob taw tes nyob rau hauv lub unpredictable tsis ua hauj lwm ntawm structural phaj vim microscopic inclusions thiab grain ciam impurities.
Txuj kev lag luam-qib npib tsib xee alloys feem ntau raug kev txom nyem los ntawm cov ciam teb embrittlement vim muaj cov phosphorus (P), sulfur (S), thiab txhuas (Pb). Peb qhov zoo tshaj plaws GH4169 phaj (sib npaug rau Inconel 718) tshwj xeeb yog tsim los daws cov kev pheej hmoo no, ua kom muaj kev ntseeg siab tshaj plaws thiab kev ua haujlwm ntev.

3. VIM + VAR Dual Melting txheej txheem rau GH4169 Alloy daim hlau
Txhawm rau kom ua tiav "zero- tsis zoo", peb mus dhau qhov hluav taws xob arc rauv (EAF) melting. PebGH4169 steel phajntiav ob lub tshuab nqus tsev refining txheej txheem:
VIM + VAR Dual Melting Process
VIM (Nqus Induction Melting):Ua nyob rau hauv ib qho chaw nqus nqus nqus, tshem tawm cov pa yaj (oxygen, nitrogen) thiab cov impurities volatile.
VAR (Nqus Arc Remelting):Eliminates non-metallic inclusions, forming a highly dense, uniform grain structure, preventing "freckles" and segregation.
Qhov tshwm sim:Ib qho ultra- huv microstructure, ua rau 30% cov khoom siv lub neej ntev dua piv rau cov qauv kev lag luam hlau, txuas ntxiv lub sijhawm nruab nrab ntawm kev saib xyuas (MTBO) rau cov khoom siv hauv Lavxias.
