Sigma phase in the cast alloy based on the FeB3BAl intermetallic phase
Journal Title: Archiwum Odlewnictwa - Year 2011, Vol 11, Issue 2
Abstract
The paper presents study results for cast alloy based on the FeB3BAl intermetallic phase. The study material was Fe-28Al-5Cr-1Mo-0,1Zr- 0,005B% at. alloy in the cast state. The microscopic research, phase analysis with X-ray diffraction, bending test and observation of the alloy surface exposed to corrosion have been performed. It has been found that presence of the sigma phase in the material structure influences high hardness of the tested alloy, its susceptibility to brittle fracture and favours the intercrystalline corrosion.
