Fa'amaa'a tausaga uamea uamea fa'alava
Fa'amatalaga Puupuu:
O le faʻamaʻaina o tausaga, e taʻua foi o le faʻamaʻaina o timuga, o se togafitiga vevela lea e faʻaleleia ai le malosi ma le maʻaʻa o nisi uʻamea, e aofia ai le uʻamea uʻamea. fa'amalosia meafaitino.
Pa Fa'amea Fa'ama'a'i Vaitausaga-Ma'a'a:
Forgings o vaega uʻamea e faʻapipiʻiina e ala i se faʻagasologa faʻasolosolo, lea e faʻamafanafanaina ai le mea ma faʻamalo pe faʻapipiʻi i le fomu e manaʻomia. E masani ona filifilia le uʻamea uʻamea mo lo latou teteʻe, malosi, ma le tumau, e faʻaogaina ai mo le tele o talosaga, e aofia ai le aerospace. , suauʻu ma kesi, ma isi mea.O le faʻapipiʻiina o le paʻu o se ituaiga faʻapitoa o uʻamea faʻapipiʻi e masani ona i ai se umi, foliga saʻo, e tutusa ma se pa poʻo se faʻamau. e manaʻomia, e pei o le fausiaina o fausaga poʻo le avea ma mea mata mo le faʻaogaina atili.

O le a le u'amea fa'ama'a'a o timuga?
u'amea fa'ama'a'a uamea, e masani ona ta'ua o le "PH stainless steel," o se ituaiga o u'amea fa'ama'a'a e faia se fa'agasologa e ta'ua o le fa'ama'a'a o timuga po'o le fa'ama'a'a tausaga. O lenei faiga e faʻaleleia ai mea faʻainisinia o mea, aemaise lava lona malosi ma le maaa. O le timu e sili ona taatele faʻamaʻaina uamea stainless o17-4 PH(ASTM A705 Grade 630), ae o isi togi, e pei o le 15-5 PH ma le 13-8 PH, o loʻo pa'ū foi i lenei vaega. O uʻamea faʻamaʻaina faʻamaʻaina e masani ona faʻapipiʻiina ma elemene e pei o le chromium, nickel, copper, ma o nisi taimi alumini. O le faʻaopoopoga o nei elemene faʻafefiloi e faʻamalosia ai le faʻavaeina o faʻalavelave i le faagasologa o togafitiga vevela.
E fa'afefea ona fa'ama'a'a le timu uamea?
tausaga fa'ama'a'aina uamea e aofia ai se faiga e tolu-laasaga. I le taimi muamua, o le meafaitino e feagai ma se togafitiga fofo maualuga-vevela, lea e faʻamavaeina ai atoms solute, ma fausia ai se vaifofo e tasi. O lenei mea e oʻo atu ai i le fausiaina o le tele o microscopic nuclei poʻo "sone" i luga o le uamea. Mulimuli ane, o le fa'afefe vave e tupu i tua atu o le fa'atapula'aina o le solubility, o le fatuina o se vaifofo malosi supersaturated i se tulaga metastable. I le laasaga mulimuli, o le vaifofo supersaturated e vevela i se vevela vaeluaga, fa'aoso timuga. Ona teuina lea o mea i lenei tulaga seia oo ina maaa. O le fa'ama'a'a manuia o tausaga e mana'omia ai le tu'ufa'atasiga o mea fa'apipi'i ia i totonu o le tapula'a solubility, fa'amautinoaina le lelei o le fa'agasologa.
O a ituaiga o u'amea malo uamea?
O u'amea fa'ama'a'a o timuga e maua mai i ituaiga eseese, e fa'atutuina ta'itasi ina ia fa'amalieina fa'atinoga ma mana'oga fa'aoga. O ituaiga masani e aofia ai 17-4 PH, 15-5 PH, 13-8 PH, 17-7 PH, A-286, Custom 450, Custom 630 (17-4 PHMod), ma Carpenter Custom 455. O u'amea nei e ofoina atu le tu'ufa'atasiga o le malosi maualuga, tete'e o le pala, ma le ma'a'a'a, ma fa'aigoa mo pisinisi eseese e pei o le va'alele, ta'avale, foma'i, ma le gaosiga o vaila'au. Ole filifiliga ole u'amea-fa'ama'a'aina u'amea fa'alagolago i mea taua e pei ole siosiomaga fa'aoga, fa'atinoga o meafaitino, ma fa'amatalaga gaosiga.
