No ka mea, kuhiliʻolehao haohoʻohana pinepine ʻia i ke kūlana kī o ka mīkini, no laila ke ʻano o loko o ka stainlesshao haohe mea nui loa.No ka maikaʻi o loko o ka stainlesshao haoʻAʻole hiki ke hoʻāʻo ʻia e ke ʻano intuitive, no laila ua hoʻohana ʻia nā ʻano loiloi kino a me nā kemika e hoʻāʻo ai.

ʻO ka mea mua, nā waiwai mechanical o ka forgings
ʻO nā mea mechanical onā kalaiwahoʻoholo ʻia e like me nā koi huahana.Hoʻokaʻawale ʻia nā ʻano hoʻāʻo i ka hoʻāʻo paʻakikī, ka hoʻāʻo tensile, ka hopena hopena a me ka hoʻāʻo luhi.
1. Hoao paakiki
ʻO ka paʻakikī ke kūpaʻa deformation o ka ʻili waiwai, he kuhikuhi ia e ana i nā mea metala palupalu paʻakikī.Loaʻa i ka paʻakikī a me nā mea ʻenehana ʻē aʻe kekahi pilina kūloko, no laila hiki ke koho ʻia nā waiwai mechanical ʻē aʻe e ka waiwai paʻakikī.ʻAʻole pono ka hoʻāʻo paʻakikī e hoʻomākaukau i nā laʻana kūikawā, ʻaʻole hoʻi e luku i ka specimen, no laila ʻo ka hoʻāʻo paʻakikī ka mea maʻamau i hoʻohana ʻia i ka hana ʻana i kahi ʻano hoʻāʻo waiwai mechanical.
ʻO nā ʻano hoʻāʻo paʻakikī maʻamau a me nā waiwai like ʻole: Brinell hardness (HB), Rockwell hardness (HRC), Vickers hardness (HV), Shore hardness (HS), a me ka mea hōʻike paʻakikī e pili ana.
2. Ho'āʻo tensile
Ma ka hoʻohana ʻana i ka ukana tensile i ka specimen o kahi ʻano e ka mīkini tensile, ua ana ʻia ke koʻikoʻi elongation proportional, yield point, tensile ikaika, elongation a me ka hōʻemi ʻana o ka ʻāpana o ka mea metala.
3. Ho'āʻo hopena
Loaʻa ka paʻakikī paʻakikī o ka metala ma o ka hoʻohana ʻana i ka pendulum kiʻekiʻe e hoʻopā ai i ka specimen me ka notch.
4. Hoao luhi
Hiki ke ana ʻia ka palena luhi a me ka ikaika luhi o ka metala ma hope o ke koʻikoʻi hou a i ʻole ka hoʻololi ʻana.
ʻElua, non destructive inspection of forging
Hiki ke hoʻokaʻawale ʻia ka hoʻāʻo nondestructive i ka hoʻāʻo radiographic, ka hoʻāʻo ultrasonic, ka hoʻāʻo ʻana i ka ʻāpana magnetic, ka hoʻāʻo seepage a me ka hoʻāʻo ʻana i kēia manawa.Hoʻohana pinepine ʻia nā forgings i ka hoʻāʻo ʻana i ka ultrasonic a me ka hoʻāʻo ʻana i nā ʻāpana magnetic.
1. Nānā kani ultrasonic
ʻO ka hawewe kani kani (ʻoi aku ka nui o ka alapine ma mua o 20000Hz) e noʻonoʻo a hoʻopaʻa i ke kikowaena o nā mea like ʻole.No laila, inā loaʻa nā hemahema o nā mea like ʻole i nā mea paʻa, e hana ʻia ka noʻonoʻo nalu a me ka attenuation.Hiki ke hoʻoholo ʻia ke ola ʻana o nā hemahema e nā hōʻailona nalu.
No ka nui a me ka waenanā kalaiwa'O ka ho'ā'o ultrasonic kekahi o nā mea nui o ka ho'ā'o nondestructive.
2. Nānā mākēneki
Hiki ke ʻike ʻia nā hemahema e like me nā māwae, nā pores a me nā mea hoʻohui ʻole ma ka ʻili a kokoke i ka ʻili o ka forging e ka nānā ʻana i nā ʻāpana magnetic.Ma muli o kāna mau mea hana maʻalahi, hana maʻalahi a me ka naʻau kiʻekiʻe, hoʻohana pinepine ʻia kēia ʻano e hoʻāʻo ai i nā forgings make liʻiliʻi a me ka liʻiliʻi i hana ʻia i ka nui.
ʻEkolu, haʻahaʻa mana a me ka haʻihaʻi ho'āʻo
ʻO ka nānā haʻahaʻa haʻahaʻa ʻo ia ka laʻana ma hope o kahi nui o ka hana ʻana, a laila me ka maka ʻōlohelohe i 10 ~ 30 mau manawa i ke aniani hoʻonui e nānā i ka hāpana, no laila e ʻike i nā hemahema o ke kila kila.Hiki ke nānā ʻia ka streamline, dendrite, loose, naphthalene, stone fracture a me nā hemahema ʻē aʻe ma o ka ʻoki ʻana i nā laʻana wafer a me ka etching acid.I mea e ʻike ai i ka hoʻokaʻawale ʻana, ʻoi aku ka nui o ka puʻunaue like ʻole o ka sulfide, hoʻohana ʻia ke ʻano paʻi sulfur.
ʻEhā, nānā mana kiʻekiʻe
E hana ʻia nā mea hao kila i kekahi laʻana ma lalo o kahi microscope e nānā i nā forgings kūloko (a i ʻole nāhaʻi) ma ke kūlana o ka hui a i ʻole nā ​​hemahema microscopic.Hiki ke nānā ʻia ke ʻano o loko a me ka hoʻopili ʻana o ka forging ma ke ʻoki ʻana i ka hāpana longitudinal.Hiki ke nānā ʻia nā hemahema o ka ʻili e like me ka decarburization, coarse-grained, carburized a me nā papa paʻakikī ma ke ʻoki ʻana i nā laʻana transverse.
