1. Te Hanga Metallography
Ko te metallography tētahi o ngā tikanga matua mō te wehewehe i ngā paipa maitai whakarewa mai ingā paipa maitai kore honongaKāore ngā paipa maitai whakarewa ātete-teitei e tāpiri rauemi whakarewa, nō reira he tino whaiti te hononga whakarewa i roto i te paipa maitai whakarewa. Mena ka whakamahia te tikanga huri taratara, kātahi ka waikura, kāore e kitea mārama te hononga whakarewa. Kia oti te whakarewa i te paipa maitai whakarewa ātete-teitei, ā, kāore anō kia whakamahanatia, ka rerekē te hanganga whakarewa i te rauemi matua o te paipa maitai. I tēnei wā, ka taea te whakamahi i te tikanga whakarewa hei wehewehe i ngā paipa maitai whakarewa mai i ngā paipa maitai kore hononga. I roto i te tukanga wehewehe i ngā paipa maitai e rua, me tapahi he tauira iti he 40mm te roa me te whānui i te pūwāhi whakarewa, ka mahi i te huri taratara, te huri pai me te whakakanapa, kātahi ka tirohia te hanganga i raro i te karu hiko whakarewa. Ina kitea te ferrite me te widmanstatten, te rauemi matua me te hanganga rohe whakarewa, ka taea te wehewehe tika i te paipa maitai whakarewa me te paipa maitai kore hononga.
2. Tikanga waikura
I roto i te tukanga whakamahi i te tikanga waikura hei wehewehe i ngā paipa maitai whakarewa me ngā paipa maitai kore hononga, me whakakanapa te whakarewa o te paipa maitai whakarewa kua tukatukahia. Kia oti te whakakanapa, me kitea ngā tohu whakakanapa. Kātahi ka whakakanapahia te mata pito ki te pepa kirikiri i te whakarewa, ā, ka rongoatia te mata pito ki te otinga waipiro waikawa hauota 5%. Mena ka puta he whakarewa mārama, ka taea te whakaatu he paipa maitai whakarewa te paipa maitai. Kāore he rerekētanga mārama i te mata pito o te paipa maitai kore hononga i muri i te waikura.
3. Wehewehea ngā paipa maitai whakarewa me ngā paipa maitai kore hononga i runga i te tukanga
I roto i te tukanga wehewehengā paipa maitai kua whakarewainame ngā paipa maitai kore hononga e ai ki te tukanga, ka honoa ngā paipa maitai kua whakapirihia katoatia kia rite ki ngā tukanga pēnei i te hurihuri makariri me te whakaputa. Hei tāpiri, ina whakamahia ngā paipa whakarewa pewa auau-teitei, auau-iti me ngā paipa whakarewa ātete ki te whakarewa i ngā paipa maitai, ka hangaia te whakarewa paipa porowhita me te whakarewa paipa tuitui tika, ka hangaia he paipa maitai porowhita, he paipa maitai tapawhā, he paipa maitai porowhita, he paipa maitai tapatoru, he paipa maitai hexagonal, he paipa maitai memenge, he paipa maitai waru-taumata, me ngā paipa maitai uaua ake. I roto i te poto, ka hangaia he paipa maitai o ngā āhua rerekē e ngā tukanga rerekē, kia mārama ai te wehewehe i ngā paipa maitai kua whakapirihia me ngā paipa maitai kore hononga. Heoi, i roto i te tukanga wehewehe i ngā paipa maitai kore hononga e ai ki te tukanga, ka wehewehea te nuinga i runga i ngā tikanga maimoatanga hurihuri wera me te hurihuri makariri, ā, e rua ngā āhua matua o ngā paipa maitai kore hononga, arā, he paipa maitai kore hononga hurihuri wera me ngā paipa maitai kore hononga hurihuri makariri. Ka hangaia ngā paipa maitai kore hononga hurihuri wera mā te poka, te hurihuri me ētahi atu tukanga, inā koa ko ngā paipa maitai kore hononga whānui me te matotoru ka honoa e tēnei tukanga; Ka hangaia ngā paipa e tōia ana i te matao mā te tōia matao o ngā paipa, ā, he iti ake te kaha o te rauemi, engari he maeneene ngā mata o waho, o roto hoki.
