Q460 saxan bir daawaha leh oo dhumucdiisuna way culus tahay
sharaxaada alaabta
Sharaxaada:
Q460 waa bir aad u yar oo awood sare leh. Q waxay ka dhigan tahay xoogga birta, 460 waxay ka dhigan tahay 460 MPa, mega waa awoodda 6aad ee 10,
iyo Pa waa unugga cadaadiska Pascal. Q460 waxay ka dhigan tahay in qallafsanaanta caagga ah ee birta ay dhici doonto oo keliya marka xoogga birta
wuxuu gaarayaa 460 MPa, taas oo ah, marka xoogga dibadda la sii daayo, birta waxay ilaalin kartaa oo kaliya qaabka xoogga mana soo laaban karto.
qaabkeeda asalka ah. Xooggan ayaa ka weyn kan birta caadiga ah.
Iyadoo lagu saleynayo hubinta kaarboonka hooseeya ee u dhigma, Q460 waxay si habboon u kordhisaa nuxurka walxaha microalloying. alxanka wanaagsan
Waxqabadku wuxuu u baahan yahay kaarboon yar oo u dhigma birta, iyo kororka walxaha microalloying waxay kordhisaa xoogga birta
iyadoo sidoo kale kordhinaysa kaarboonka u dhigma birta. Nasiib wanaag, kaarboonka dheeriga ah ee u dhigma waa mid aad u yar, markaa ma saameyn doonto
weldability ee birta.
