Environmental Embrittlement and Preferred Orientation of Cold-Rolled and Annealed Fe_3 (Al, Cr, Zr) Alloy at Ambient Temperature

摘要

The room temperature tensile properties of cold-rolled and annealed Fe_3 (Al, Cr,Zr) alloy are similar to those of warm--rolled Fe_3Al alloys. The cold-rolled Fe_3 (Al,Cr, Zr) alloy is also susceptible to test environments. It has been shown that the ductility in vari- ous environments decreases in sequence of oxygen-- oil-- air-- distilled water. The results of X-ray diffraction analysis show that (211 ) preferred orientation of B2 phase appears in cold-rolled Fe_3 (Al, Cr, Zr) alloy after recrystallization annealing.
