Abstract

Abstract

The embrittlement tendency of deep drawing shell steel 15A which hao two different morphologies of ferrite (W-ferrite and mass ferrite) has been studied by means of two methods, i.e,impact test with sharp notch at room temperture and high speed tensile test with notch at -80℃. The resulfs showed that the specimens with mass ferrite were more brittle than those with W-ferrite when the grain size of the prior Austenite is the same,These results haoe been further discussed.
