Paipu hukihuki anu

ʻO ka wehewehe pōkole:

ʻO ka paipu hukihuki anu i nā hiʻohiʻona o ke kiʻekiʻe kiʻekiʻe, kiʻekiʻe maʻalahi, maikaʻi ka hoʻomaʻemaʻe ʻana o ka paia o loko, ʻo ka paipu kila ke kū i ke kaomi kiʻekiʻe me ka ʻole o ka leakage, ke kuʻi anu me ka ʻole o ka deformation, flaring, flattening me nā māwae, etc., a hiki ke hoʻohana ʻia no nā ʻano paʻakikī. deformations a me ka hana mechanical.ʻO ka hoʻohui kemika o nā paipu huki anu me ka kalapona C, silicon Si, manganese Mn, sulfur S, phosphorus P, a me chromium Cr.

1, ʻO ka hiʻohiʻona nui o ka paipu kila liʻiliʻi maʻamau, ʻaʻohe ona wili wili a hiki ke kū i ke kaomi nui.Hiki i ka huahana ke 'ano 'o'ole'a loa e like me ka ho'olei 'ia a i 'ole nā ​​'āpana huki anu.

2, ʻO ka paipu kikoʻī kikoʻī i huki ʻia ʻo ia ka lua o loko, a ʻo ka nui o ka pā o waho he ʻoluʻolu a me ka palaka, a he kiʻekiʻe loa ka pololei.

ʻO ke anu anuanu

Hōʻike ʻia ka haʻahaʻa anu (a i ʻole ka haʻahaʻa haʻahaʻa haʻahaʻa) o ka paipu kila ʻālohilohi i ʻōwili ʻia e ka wela hoʻololi Tc.Loaʻa ka hao maʻemaʻe kiʻekiʻe (0.01%C) i ka Tc o 100C, a ua hoʻopau piha ʻia ma lalo o kēia mahana.ʻO ka hapa nui o nā mea hoʻohui i loko o ka paipu kila alohilohi e hoʻokiʻekiʻe i ka paʻakikī o ka hoʻololi ʻana i ka mahana o ka paipu kila a hoʻonui i ke ʻano o ka brittleness anu.Ke ʻoi aku ka haʻihaʻi ductile ma luna o ke ana wela, ʻo ka haʻihaʻi o ka paipu kila ʻālohilohi i hoʻoheheʻe ʻia he dimple fracture, a i ka wā e haʻihaʻi ai i ka haʻahaʻa haʻahaʻa, he haʻihaʻi ia.

ʻO nā kumu o ka haʻahaʻa haʻahaʻa embrittlement o ke anuanu-rolled precision ʻālohilohi paipu kila:
(1) Ke ālai ʻia nā dislocations i hana ʻia e ke kumu dislocation i ka wā deformation e nā pilikia (e like me nā palena o ka palaoa, ka lua like), ʻoi aku ke koʻikoʻi kūloko ma mua o ka ikaika theoretical o ka paipu kila a me ke kumu o nā microcracks.
(2) Hoʻokumu ʻia kekahi mau dislocations i hoʻopili ʻia i microcrack ma ka palena ʻai.
(3) ʻO ka pane ʻana ma ka hui ʻana o ʻelua {110) mau kaula paheʻe ke kumu o ka hoʻoneʻe ʻana i ka %26lt;010%26gt;, ʻo ia ka microcrack me ke ʻano wedge, hiki ke māhele ʻia ma ka mokulele ʻoki {100} (e nānā i ke Kiʻi 1b).

ʻO nā kumu e hoʻonui ai i ka palupalu anu o nā paipu kila ʻālohilohi i ʻōwili ʻia:
(1) Mea hoʻoikaika paʻa paʻa.Hoʻonui ka Phosphorus i ka wela hoʻololi ʻoi aku ka ikaika loa;aia kekahi molybdenum, titanium a me vanadium;ke haʻahaʻa ka ʻike, he liʻiliʻi ka hopena, akā i ka wā kiʻekiʻe ka ʻike, ʻo nā mea e hoʻonui ai i ka paʻakikī-brittle hoʻololi wela he silicon, chromium a me ke keleawe;ho'ēmi i ka toughness-brittleness ʻO ka mahana hoʻololi he nickel, aʻo ka mahana hoʻololi paʻakikī-brittle he manganese.
(2) Nā mea e hoʻokumu ana i ka pae ʻelua.ʻO ka mea koʻikoʻi loa no ka haʻalulu anu o nā paipu kila alohilohi me ka lua o ka hana he carbon.Me ka piʻi ʻana o ka ʻike kalapona i loko o nā paipu kila māmā, hoʻonui ka ʻike o ka pearlite i loko o nā paipu kila kila kila, me ka piʻi ʻana o 1% o ka nui o ka pearlite.Ua hoʻonui ʻia ka mahana hoʻololi ʻoʻoleʻa-brittle e 2.2°C ma ka awelika.Hōʻike ka Figure 2 i ka hopena o ke kalapona i loko o ke kila ferrite-pearlite ma ka brittleness.ʻO ka hoʻohui ʻana o nā mea microalloying e like me ka titanium, niobium a me ka vanadium e hana i nā nitrides i hoʻopuehu ʻia a i ʻole carbonitrides, e hoʻonui ai i ka wela o ka hoʻololi ʻana i ka paʻakikī o nā paipu kila alohilohi.
(3) Hoʻopili ka nui o ka palaoa i ka wela o ka hoʻololi ʻana i ka paʻakikī.Ke hoʻomāhuahua aʻe ka ʻōpala, piʻi ka wela o ka hoʻololi ʻana i ka paʻakikī.ʻO ka hoʻomaʻemaʻe ʻana i nā kīʻaha e hōʻemi ana i ke ʻano o ke anuanu o nā paipu kila ʻālohilohi i ʻōwili ʻia, ʻo ia ke ʻano i hoʻohana nui ʻia.
