Ko te paerewa e hiahia ana mehemea he tohu te ahua crimping o te tauranga honohono. Ko te porosity o te waea crimping kāpeka e pā ana ki te ōwehenga o te rohe kore whakapā o'Ko te waahanga hono i roto i te tauranga crimping ki te katoa o te rohe, he tawhā nui e pa ana ki te haumaru me te pono o te tauranga crimping. Ko te porosity tiketike rawa ka paheke te whakapiri, ka piki ake te parenga me te wera, na reira ka pa ki te pumau me te haumaru o te hononga hiko. Na reira, ka hiahiatia nga taputapu tātari metallographic ngaio mo te kitenga porosity mata me te tātari. Ko te tapahi tauira Metallographic, te tauira whakarewa me te miihini whakakorikori, me te miihini miihini hei whakatauira me te whakarite i te tauranga, katahi ka tātarihia te whakaahua whakairoiro e te rorohiko miihini miihini mo te tirotiro i te waahanga whiti.
Te tukanga whakarite tauira: Ko te tauira hei tirotirohia (me karohia nga riu whakakaha o te tauranga) ka tapahia me te tauira ki te miihini tapahi tauira miihini-e taunaki ana kia whakamahia he miihini tapahi tika mo te tapahi, a ko te mea mahi ka whakauruhia ki roto i te tauira me nga papa e rua ma te whakamahi i te miihini whakakikorua metara, katahi ko te mata o te tirohanga kua whakakohia me te mata whakaata me te whakakorikori me te mata whakaata me te whakakorikori. kua waikura matū ka waiho ki raro i te karuiti whakarewa hei tirotiro me te tātari.
