摘要: Ti–48Al–6Nb porous alloys with different phase skeletons were synthesised by powder metallurgy at temperatures. TiAl3 achieved 700°C covered corrosion products and fractures led to pores collapse. TiAl 900°C obvious pits pore diameter increasing. And Ti3Al/TiAl 1350°C exhibit the best acid resistance least mass loss of 1.853 mg m–2. Skeletons diameters remained stable just fully lamellar structures emerged. In addition, Nb2Al phases presented better than NbAl3 in contributing alloys.
