W6Mo5Cr4V2(M2) u'amea lapotopoto uamea taai vevela

M2 o le molybdenum faasologa maualuga-saosaoa uʻamea, o loʻo i ai le lelei o le carbide inhomogeneity laiti ma maualuga toughness. Faigofie i le overheating, e tatau ona matua pulea le tineia vevela vevela, o le sili atu le puipuiga malu mo togafitiga vevela. Ona o lona maaa ma le faʻaogaina, faʻaaogaina i le gaosiga o le tipi sili atu ona faigata i le tipiina o mea faigaluega. M2 maualuga-saosaoa uʻamea ma carbide orientation e sili atu, o lea o le sili atu le puipuiga malu mo togafitiga vevela e talafeagai mo le faʻafefeteina ma uta teʻi.
