Qhov porosity ntawm sintered ntxeem tau titanium daim hlau tuaj yeem muaj kev cuam tshuam loj rau lawv cov khoom siv dag zog. Feem ntau, raws li qhov porosity ntawm lub phaj nce, cov neeg kho tshuab lub zog txo.
Qhov no yog vim hais tias cov pores ua raws li kev ntxhov siab concentrators, uas tuaj yeem ua rau cov khoom tsis muaj zog thiab ua rau nws muaj kev cuam tshuam ntau dua rau kev puas tsuaj hauv qab load. Raws li tus naj npawb thiab qhov loj ntawm qhov pores nce, cov khoom yuav tsis ntom thiab ntxeem tau ntau, uas tuaj yeem txo nws lub zog tag nrho.

Txawm li cas los xij, kev sib raug zoo ntawm porosity thiab mechanical zog tsis yog ib txwm ncaj nraim. Qee zaum, qhov porosity tuaj yeem txhim kho cov khoom siv kho tshuab. Piv txwv li, ib qho me me ntawm porosity tuaj yeem txhim kho qhov toughness thiab ductility ntawm cov khoom, ua rau nws tiv taus deformation ntau dua thiab muaj peev xwm nqus tau lub zog ua ntej tawg.
Cov txiaj ntsig tshwj xeeb ntawm porosity ntawm lub zog siv tshuab yog nyob ntawm ntau yam, suav nrog qhov loj thiab kev faib tawm ntawm qhov pores, txheej txheem tsim khoom, thiab kev npaj siv cov khoom siv. Yog li ntawd, nws yog ib qho tseem ceeb kom ua tib zoo xav txog qhov porosity ntawm sintered ntxeem tau titanium daim hlau thaum tsim cov khoom lossis cov khoom uas yuav tsum tau muaj cov khoom siv tshwj xeeb.
