What is the difference between austenite and martensite?
Thread Content
I’m new to this subject, so I have a rather basic question: what’s the difference between austenite and martensite? I just can’t figure it out
For more details, see: http://zhidao.baidu.com/question/10153430.html?fr=qrl&fr2=query
It is mainly due to magnetism; austenite is non-magnetic, while martensite is magnetic
Is austenitic stainless steel used in the production of most branded products?
Austenite is a interstitial solid solution of carbon in γ-Fe, with a face-centered cubic crystal structure; it possesses good plasticity and is easy to deform； Martensite is a supersaturated solid solution of carbon in α-Fe, possessing significantly high strength and hardness.
Austenite has good weldability, while martensite has poor weldability; it tends to undergo welding hardening, and cold cracks appear after welding
The tempering temperatures are different, and so are the composition levels
