I roto i ngā hua ahumahi, he whānuitia te whakamahinga o te maitai taputapu i roto i ngā pūnaha tuku hiko o ngā taputapu miihini maha nā te mea he kaha teitei, he ātete ki te kakahu me te ngenge. Ka pā tika tōna kounga ki te kounga me te roa o te ora o ngā taputapu. Nō reira, he mea tino nui te whakahaere kounga o te maitai taputapu. I te wā e whiriwhiri ana, me whai whakaaro ki tōna kaha, tōna pakari me tōna ātete ki te kakahu. I mua i te tukatuka i te maitai taputapu, me tātarihia te hanganga whakarewa, te pakeke, te hanganga matū, me ētahi atu o te rauemi. Ko te hanganga whakarewa me te pakeke o te maitai taputapu he tohu matua mō te aromatawai i ōna āhuatanga miihini, ngā pānga maimoatanga wera me te roa o te ora. Me tino whai te tātari whakarewa me te whakamātautau pakeke o te maitai taputapu i te tukanga paerewa, me te whakatakoto i tētahi mahere whakamātautau i runga i ngā āhuatanga rauemi me ngā tikanga mahi:
Tuatahi, te tātaritanga whakarewa. He nui te awe o te hanganga whakarewa o te maitai taputapu ki tōna mahi, pērā i te hohonutanga o te paparanga waro, te rahi o te kōpura, te tohatoha waro, me ētahi atu. Me whakatau ngā mahi tātari, pērā i te tauira, te whakarite tauira, te waikura, kātahi ka tirohia te hanganga. Me whakahua anō hoki ngā momo kiko noa, pērā i te martensite, te bainite, te pearlite, me pēhea te aromatawai mēnā ka tutuki ēnei kiko i ngā paerewa.
Kātahi ka tae mai te whakamātautau pakeke. He hononga tika te pakeke o te maitai taputapu ki te ātete kakahu me te kaha. Ko ngā tikanga whakamātautau pakeke noa ko te pakeke o Rockwell, te pakeke o Brinell, te pakeke o Vickers, me te pakeke pea o te mata o Rockwell mō ngā paparanga warowaihā. Me whakamārama ngā āhuatanga e tika ana mō ngā tikanga whakamātautau rerekē, pērā i te Vickers, te mata rānei o Rockwell mō ngā paparanga warowaihā, me te Brinell, te Rockwell rānei mō te pakeke whānui. I taua wā anō, me whakahua ngā paerewa whakamātautau, pērā i te ASTM, te GB rānei, me ngā whakatūpato i te wā o te whakamātautau, pērā i te whiriwhiri i ngā pūwāhi whakamātautau, te maimoatanga mata, me ētahi atu.
I mua i te tātari, me tapahi tuatahi tātou i te maitai taputapu me te tauira. Kei raro nei ka whakamahia e mātou te mīhini tapahi tauira whakarewa tika hei tauira hei whakaatu i te tukanga tapahi tauira.
1. Tangohia te mea mahi ka whakapiripiri ki te whakapiri tere.
2. I muri i te whakapuru i te mea mahi, whakakakahuria te taupoki tiaki.
3. Whakatakotoria ngā tawhā tapahi ki te mata, ka tīmata i te kaupapa tapahi
4. Whakatuwheratia te taupoki o runga, ka tangohia te tauira kua tapahia hei whakaoti i te tukanga tapahi tauira.
Ka taea te whakamahi i ngā tauira kua tapahia mō ngā tukanga whakarite tauira o muri mai pēnei i te whakairi, te huri, me te whakakanapa, ā, muri iho ka taea te whakahaere i te whakamātautau pakeke o ngā taputapu, te tātari whakarewa rānei.
