Abstract

Abstract

Crack formation of Fe-Cr-Al alloy in wiredrawing process has been studied by means of acoustic emiassion and electron microscopy techniques.It is found that the major reason is due to Hydrogen-induced cracking in wiredrawing deriction. As Carbide precipitates at grain boundary, Ductility of alloy is low.In addition, brittleness tranoformation temperture of alloy is high, Crack may be induced by thermal stress.
