1. Nā waiwai mīkini o ke kila
1. Ke kiko hua (σs)
Ke hohola ʻia ke kila a i ʻole ka laʻana, ke ʻoi aku ke koʻikoʻi ma mua o ka palena elastic, ʻoiai inā ʻaʻole e piʻi ke koʻikoʻi, ke hoʻomau nei ke kila a i ʻole ka laʻana i ka deformation plastik maopopo.Ua kapa ʻia kēia ʻano ʻo ka hāʻawi ʻana, a ʻo ke koʻikoʻi haʻahaʻa loa i ka wā e hāʻawi ai ʻo ia no ka helu hua.E lilo ka Ps i ka ikaika o waho ma ke kiko hua s, a o Fo ka apana kea o ka laana, alaila, ke kiko hua σs =Ps/Fo(MPa).
2. Ka ikaika hua (σ0.2)
ʻAʻole ʻike nui ʻia ka helu hua o kekahi mau mea metala, a paʻakikī ke ana ʻana.No laila, no ke ana ʻana i nā hiʻohiʻona hua o ka mea, ʻo ke koʻikoʻi i ka wā e like ai ka deformation plastic residual mau i kahi waiwai (maʻamau 0.2% o ka lōʻihi kumu), i kapa ʻia ke kūlana.Ka ikaika hāʻawi a i ʻole ka hāʻawi wale ʻana i ka ikaika σ0.2.
3. Ka ikaika uʻi (σb)
ʻO ke koʻikoʻi koʻikoʻi koʻikoʻi i loaʻa e ka mea mai ka hoʻomaka a hiki i ka manawa o ka haki ʻana i ka wā o ke kaʻina hana.Hōʻike ia i ka hiki o ke kila ke pale i ka haki.E pili ana i ka ikaika tensile, ʻo ia ka ikaika compressive, ka ikaika flexural, etc. E hoʻokuʻu iā Pb ka ikaika tensile kiʻekiʻe loa i hiki ma mua o ka haki ʻana o ka mea, a ʻo Fo ka ʻāpana cross-sectional o ka hāpana, a laila ka ikaika tensile σb=Pb/Fo (MPa). ).
4. Elongation (δs)
Ma hope o ka haki ʻana o ka mea, ua kapa ʻia ka pākēneka o kāna elongation plastic i ka lōʻihi o ka hāpana kumu mua.
5. Lakiō hua (σs/σb)
ʻO ka lakio o ka helu hua (ka ikaika hua) o ke kila i ka ikaika tensile i kapa ʻia ʻo ka yield ratio.ʻOi aku ka nui o ka ratio hua, ʻoi aku ka kiʻekiʻe o ka hilinaʻi o nā ʻāpana hana.ʻO ka mea maʻamau, ʻo 0.6-0.65 ka hopena o ke kila kalapona, ʻo ke kila haʻahaʻa haʻahaʻa he 0.65-0.75, a ʻo ke kila kila kila he 0.84-0.86.
6. Oolea
Hōʻike ka paʻakikī i ka hiki i kahi mea ke pale aku i ke kaomi ʻana i kahi mea paʻakikī i kona ʻili.ʻO ia kekahi o nā hōʻailona hana nui o nā mea metala.ʻO ka maʻamau, ʻoi aku ka kiʻekiʻe o ka paʻakikī, ʻoi aku ka maikaʻi o ka pale ʻana.ʻO nā hōʻailona paʻakikī maʻamau ʻo Brinell hardness, Rockwell hardness a me Vickers hardness.
1) ʻO Brinell paakiki (HB)
E kaomi i ka pōpō kila paʻakikī o kekahi nui (maʻa mau 10mm ke anawaena) i loko o ka ʻili o ka mea me kahi ukana (maʻamau 3000kg) a mālama iā ia no kekahi manawa.Ma hope o ka wehe ʻia ʻana o ka ukana, ʻo ka lakio o ka ukana i ka ʻāpana indentation ka waiwai paʻakikī Brinell (HB).
2) ʻO ka paʻakikī o Rockwell (HR)
Ke liʻiliʻi loa ka HB>450 a i ʻole ka hāpana, ʻaʻole hiki ke hoʻohana ʻia ka hoʻāʻo paʻakikī Brinell a pono e hoʻohana ʻia ke ana paʻakikī ʻo Rockwell.Hoʻohana ia i ka cone daimana me kahi kihi vertex o 120 ° a i ʻole he pōpō kila me ke anawaena o 1.59mm a me 3.18mm e kaomi i ka ʻili o ka mea e hoʻāʻo ʻia ma lalo o kekahi ukana, a loaʻa ka paʻakikī o ka mea mai. ka hohonu o ka indentation.E like me ka paʻakikī o ka mea hoʻāʻo, hiki ke hōʻike ʻia i ʻekolu mau unahi like ʻole:
HRA: ʻO ia ka paʻakikī i loaʻa ma ka hoʻohana ʻana i ka ukana 60kg a me kahi indenter cone daimana, a hoʻohana ʻia no nā mea me ka paʻakikī kiʻekiʻe loa (e like me ka carbide cemented, etc.).
HRB: ʻO ia ka paʻakikī i loaʻa ma ka hoʻohana ʻana i ka ukana 100kg a me ka pōlele kila paʻakikī me ke anawaena o 1.58mm.Hoʻohana ʻia ia no nā mea me ka paʻakikī haʻahaʻa (e like me ke kila annealed, hao hao, etc.).
HRC: ʻO ia ka paʻakikī i loaʻa ma ka hoʻohana ʻana i ka ukana 150kg a me ka indenter cone daimana, a hoʻohana ʻia no nā mea me ka paʻakikī kiʻekiʻe (e like me ke kila paʻakikī, etc.).
3) ʻO ka paʻakikī o Vickers (HV)
E hoʻohana i ka indenter cone diamond square me ka haʻawe o lalo o 120kg a me kahi kihi vertex o 136° e kaomi i ka ʻili o ka mea, a e puʻunaue i ka ʻili o ka lua indentation me ka waiwai ukana e loaʻa ai ka waiwai paʻakikī Vickers (HV). ).
2. ʻO nā metala ferrous a me nā mea hao ʻole
1. Metala hao
E pili ana i ka huila o ka hao a me ka hao.E like me ke kila, ka hao puaʻa, ka ferroalloy, ka hao, a me nā mea ʻē aʻe.
ʻO ka hao puaʻa e pili ana i ka huahana i hana ʻia e ka hoʻoheheʻe ʻana i ka hao hao i loko o ka umu ahi, i hoʻohana nui ʻia no ka hana kila a me ka hoʻolei ʻana.
Hoʻoheʻe ʻia ka hao puaʻa i loko o ka umu hoʻoheheʻe hao e loaʻa ai ka hao (ka hao hao-carbon alloy me kahi kalapona ʻoi aku ka nui ma mua o 2.11%), a me ka hoʻolei ʻana i ka wai hoʻolei i ka hao, ua kapa ʻia kēia ʻano hao.
ʻO Ferroalloy kahi huila i haku ʻia me ka hao, silika, manganese, chromium, titanium a me nā mea ʻē aʻe.ʻO Ferroalloy kekahi o nā mea maka no ka hana kila.Hoʻohana ʻia ia ma ke ʻano he deoxidizer a me ka mea hoʻohui mea hoʻohui no ke kila i ka wā o ka hana kila.
Ua kapaʻia nā'āpana hao-carbon me kahi kalapona ma lalo o 2.11% i kapaʻia he kila, a loaʻa ke kila ma ka hoʻokomoʻana i ka hao puaʻa no ka hana kila i loko o ka umu ahi a hoʻoheheʻeʻia e like me kekahi kaʻina hana.Loaʻa nā huahana kila i nā ʻāpana kila, nā papa hoʻolei hoʻomau a me ka hoʻolei pololei ʻana i nā ʻano kila like ʻole.ʻO ka mea maʻamau, pili ke kila i ke kila i ʻōwili ʻia i loko o nā huahana kila like ʻole.
2. Nā metala non-ferrous
ʻIke ʻia hoʻi he metala non-ferrous, pili ia i nā metala a me nā mea ʻokoʻa ʻē aʻe ma mua o nā metala ferrous, e like me ke keleawe, ka tin, ke kēpau, zinc, aluminika, a me ke keleawe, ke keleawe, nā alumini alumini, a me nā alloys amo.Eia kekahi, hoʻohana ʻia ka chromium, nickel, manganese, molybdenum, cobalt, vanadium, tungsten, titanium, etc.Hoʻohana nui ʻia kēia mau metala e like me nā mea hoʻohui alloy e hoʻomaikaʻi i ka hana o nā metala.I waena o lākou, hoʻohana nui ʻia ka tungsten, titanium, molybdenum, etc. e hana i nā pahi.paʻa paʻa.ʻO nā metala non-ferrous ma luna nei ua kapa ʻia nā metala ʻoihana, ma kahi o nā metala makamae: platinum, gula, kālā, etc.
