Nā māwae lehulehu
Ma ke alo crystallization solidified, ma lalo o ka hana o ke kiʻekiʻe wela a me ka stress, ka lattice defects neʻe a aggregate e hana i ka lua palena, i loko o ka haʻahaʻa plastic moku'āina i kiʻekiʻe wela, a me nā māwae ma lalo o ka hana o ke kaumaha.Loaʻa nā māwae multilateral i nā welds o nā metala maʻemaʻe a i ʻole nā ʻāpana austenitic hoʻokahi-phase a i ʻole ma kahi kokoke i ke kuʻina, a no ke ʻano o nā māwae wela.
Hoʻā hou i nā māwae
No nā kila me ka papa mānoanoa i hoʻopili ʻia a me kekahi mau mea hoʻohuihui e hoʻoikaika i ka ua, ua kapa ʻia nā māwae i loko o nā ʻāpana coarse-grained o ka wahi i hoʻopili ʻia i ka wela i ka wā o ka mālama ʻana i ka wela a i ʻole ka lawelawe ʻana i kekahi mahana.Hana ʻia nā māwae hoʻomaʻamaʻa ma nā ʻāpana koʻikoʻi o ka ʻāpana i hoʻopili ʻia i ka wela o nā kila ikaika kiʻekiʻe haʻahaʻa, nā kila pale wela pearlitic, nā kila kuhili ʻole austenitic a me nā mea hoʻoheheʻe nickel.
Nā māwae anu
ʻO nā māwae anu he ʻano maʻamau maʻamau o nā māwae i hana ʻia ma ka wiliwili, i hana ʻia i ka wā e hoʻomaha ʻia ai ka mahana i kahi haʻahaʻa haʻahaʻa ma hope o ka wili.Loaʻa nā māwae anu ma ka ʻāpana wela i hoʻopili ʻia o ke kila kila haʻahaʻa, ke kila kila waena, ke kalapona waena a me ke kila kalapona kiʻekiʻe.I kēlā me kēia hihia, e like me ke kuʻi ʻana i nā kila ikaika loa a i ʻole kekahi mau ʻāpana titanium, ʻike pū ʻia nā māwae anu ma ka weld metala.
E like me nā ʻano kila like ʻole a me nā hale e hoʻopili ʻia, aia nā ʻano like ʻole o nā māwae anu, hiki ke hoʻokaʻawale ʻia i nā ʻano ʻekolu.
Māka Hoʻopanee
He ʻano maʻamau o nā māwae anu.ʻO kāna hiʻohiʻona nui ʻaʻole ia e ʻike koke ʻia ma hope o ke kuʻi ʻana, akā he manawa incubation maʻamau, a he māwae me nā hiʻohiʻona lohi i hana ʻia ma lalo o ka hana i hui ʻia o ka hana paʻakikī, hydrogen a me ke koʻikoʻi kāohi.
Hoʻopi i nā māwae
ʻAʻole lohi kēia ʻano māwae, ʻike koke ʻia ma hope o ke kuʻi ʻana, i kekahi manawa i loko o ka weld, i kekahi manawa ma ka wahi wela.ʻO ka mea nui he hale paʻakikī, nā māwae i hana ʻia ma lalo o ka hana o ke koʻikoʻi welding.
Māwae Pīpika Haʻahaʻa
No kekahi mau mea me ka plasticity haʻahaʻa, i ka wā anuanu a haʻahaʻa haʻahaʻa, ʻoi aku ke koʻikoʻi i hoʻokumu ʻia e ka ikaika shrinkage ma mua o ka mālama ʻana i ka plastic o ka mea ponoʻī a i ʻole nā māwae i hoʻokumu ʻia e ka mea i lilo i mea palupalu.No ka mea, ua hana ʻia ma kahi haʻahaʻa haʻahaʻa, ʻo ia kekahi ʻano o ka māwae anu, akā ʻaʻohe mea lohi.
Haehae Lamina
Ma ke kaʻina hana o nā papa hana aila nui a me nā moku kaomi pā mānoanoa, nā māwae wāwae e like me ke kuhikuhi ʻōwili i kekahi manawa, i kapa ʻia ʻo laminar tearing.
ʻO ka mea nui ma muli o ka loaʻa ʻana o nā mea i hoʻopili ʻia (ma ka ʻaoʻao o ka ʻōwili) i loko o ka pā kila, ʻo ke koʻikoʻi i hana ʻia i ka wā kuʻi ʻana e pili pono ana i ka ʻōkuhi ʻōwili, e hopena i kahi ʻano "stepped" i loko o ka ʻāpana wela i kahi mamao loa mai ke ahi. haehae ʻia.
ʻO ka māhā ʻinoʻino
Hoʻopaneʻe ka pohā o kekahi mau hale welded (e like me nā moku a me nā paipu) ma lalo o ka hana hui ʻana o ka media corrosive a me ke kaumaha.ʻO nā mea e pili ana i ka hoʻoheheʻe ʻana i ke koʻikoʻi, ʻo ia ka mea o ka hale, ke ʻano o ke ʻano corrosive, ke ʻano o ka hale, ka hana ʻana a me ke kaʻina hana wili, ka mea wili, a me ke kiʻekiʻe o ke kaumaha.Loaʻa ka ʻinoʻino i ka wā lawelawe.
