BEHAVIOUR OF AUSTENITE UNDER IMPACT ABRASION
|
Abstract:
On the basis of the experimental results of resistance to impact-abra-sion of a newly developed austenite-bainitic ferrite dual-phase high carbon lowalloy steel with high strength, toughness and strain-hardening ability, discussionwas made on the behaviour of austenite under impact abrasion. It was found thata favourable austenite resisting to impact abrasion is only more stable and fine onewith certain high dispersion in the matrix of high strength and proper toughnesssteel. But the mechanically poor stable and coarse austenite in quantity, especiallydistributed as continuous matrix, is extremly harmful to impact abrasion resistance.
