Abstract Scope |
Liquid metal embrittlement (LME) in two newly developed alumina-forming austenitic alloys was studied at a temperature range between 600-350 °C in liquid Pb and 600-150 °C in LBE, with 50 °C intervals. Slow strain rate testing (SSRT) in a low-oxygen environment was used to evaluate the ductility of the alloys. No LME was observed in the alloys in liquid Pb and LBE, at any of the tested temperatures. The cubic FCC structure alloys and their ability to form a sufficiently protective oxide in the Pb and LBE environments are believed to be the cause that they remained unaffected by LME. Compared to BCC, the more tightly packed FCC structure may hinder or limit the ability of the HLM atoms to weaken the interatomic bonds in the solid metal atoms at the crack tip. |
