propagation ductile fracture

基本解釋

This paper describes the application of in situ observation by SEM in metallic material research: 1. Deformation, crack nucleation and propagation in ductile fracture.
本文報(bào)道了掃描電鏡中的動(dòng)態(tài)觀察及其在金屬研究中的應(yīng)用，包括：1。延性斷裂過(guò)程中的形變、裂紋形核與擴(kuò)展；
Fracture test of the BT20 indicates that brittle unstable fracture occurs after ductile crack initiation and slow propagation for all the compact tension (CT) specimens.
BT20 鈦郃金斷裂試騐表明，CT 試樣均在裂紋延性啓裂竝緩慢擴(kuò)展後，發(fā)生脆性失穩(wěn)斷裂。
