Abstract:
Because of the need of environmental protection and energy saving,automobile lightweight has become the trend of world automobile development.Low density steel with low density、high strength and toughness can reduce automobile weight as far as possible without sacrificing the strength of automobile structural parts.The current status of Fe-Mn-Al-C low density steels both at home and abroad was summarized,including the way of automobile lightweight,the structure and properties of different kinds of low density steels,and the strengthening mechanism of low density steels.
