Kuputika Phenomenon yeCold Drawn Seamless Steel Pipe

Kana machubhu esimbi asina musono achidhonzwa, inopisa yakatenderedzwa chubhu kukanganisa senge makatsemuka kana kuvapo kwepamusoro-chaiyo yekudhirowa tangi yemafuta inogadzirwa mushure mekutyoka kwakaitika mukosi, kunenge kusina kushanduka kwepurasitiki kwakaitika, kazhinji kutsemuka. Brittle fracture inokonzerwa nezvikonzero zvakasiyana-siyana. Zvakadai se: muganhu wezviyo unopera, pasinei nokuti chii chakasimba kudarika simba rematrix kana risina simba, zvose zvinokonzera kuputika; kupatsanurwa pamuganhu wezviyo inclusions yakaputsika zvikonzero; Uyezve, kunyangwe mune zvishoma kudarika muganho wegoho wemuchinjikwa pasi pemitoro yakasiyana, inogona kukonzera kuneta kutsemuka kwakaitika.

Muzhinji, iyo mechanical properties ye hydraulic (pneumatic) zvikamu zvinoshandiswa mukugadzira, zvinhu zvinofungidzirwa kuva homogeneous, zvinopfuurira, isotropic, maererano nenzira iyi yekuongorora inofungidzirwa yakachengeteka dhizaini, dzimwe nguva njodzi ichaitika kuputika. Chidzidzo chacho chakawana kuti yakaderera kushushikana brittle fracture process inoitika mune yakakwira simba simbi zvinhu, iyo zvinhu sangano iri kure nehomogeneous, isotropic. Masangano ane kuputika, pachava ne-inclusions, porosity uye zvimwe zvikanganiso zvinogona kuonekwa sezvinhu microcracks. Mukuwedzera, iyo brittle fracture uye zvakare inhengo yeakakodzera tembiricha. Kana vanhu kuburikidza netsvagiridzo vakawana kuti kana tembiricha yadonha pasi peimwe tembiricha, zvinhu zvacho zvinozoshandurwa kuita brittle state, simba rinotora simba rakaderera, chiitiko chinozivikanwa sekutonhora brittleness, saka dhizaini asiwo zvinoenderana neanoshanda tembiricha nhengo sarudza. ine yakakodzera inotonhora-brittle shanduko yekushisa yezvinhu.
