Fa'agasologa mo Vasega Eseese
Vasega D, E (DH32, DH36, EH 32, EH 36)
Vasega D ma E faasologa (inlcuding AH32 /36, DH32, DH36, EH32, EH36) fau vaa ipu uʻamea e manaʻomia lelei le maualalo o le vevela toughness ma lelei faatinoga uelo. Le gaosiga maualuga-malosi ipu uʻamea fau vaa e tatau ona normalized e ala i le pulea taʻavale ma pulea cooling po o le vevela faagasologa togafitiga ma meafaigaluega atoatoa. I le taimi lava e tasi, o le mama i totonu o le uamea o loʻo tuʻuina atu e manaʻomia le maualuga, aemaise lava o mea o loʻo i totonu o le S, P, N, 0 ma le H i totonu o le uamea e tatau ona matua faʻatonutonuina.
Fa'aopoopo Elemene Alloy e Fa'aleleia le Malosi
Ina ia faʻamautinoa le faʻatinoina o ipu vaʻa malosi-maualuga, faʻaaogaina tekinolosi micro-alloying. E ala i le faʻaopoopoina o Nb, V, Ti ma isi elemene faʻafefiloi i le uamea, faʻatasi ma le faʻatonuina o le taʻavale, o le saito e faʻamamaina ma faʻaleleia le malosi.
Fa'atonuga ole Atina'e mo le Fausiaina o Vaa
Malosiaga maualuga, faʻamatalaga maualuga, faʻatasi ai ma le tele o le vaʻa ma le saogalemu, ma suiga i faʻamatalaga faʻapipiʻi, o le manaʻoga mo panela masani A-vasega ua faasolosolo malie ona faʻaitiitia, ma o loʻo faʻateleina le manaʻoga mo paneli maualuga, lea e faʻapipiʻiina i vaʻa tetele. e 5m lautele. Papatusi, 200-300mm mafiafia laupapa vaa mafiafia faapitoa.
