▎ 摘　　要

NOVELTY - The graphene reinforcing high-performance lightweight iron-based powder metallurgy material has 0.1 to 0.5 % of iron-based material. The iron-based material includes graphite powder 0.5%, less than or equal to 0.02% phosphorus, less than or equal to 0.02% of sulfur, less than or equal to 0.15 of manganese, less than or equal to 0.05% of silicon and the rest is iron. USE - Graphene reinforcing high-performance lightweight iron-based powder metallurgy material for use in vehicle. ADVANTAGE - Improves the strength and toughness of the iron-based powder metallurgy material, which can obviously reduce the importance of iron-based powder metallurgy powder, providing a technique method for effectively made of lightweight iron base portion for vehicles. DESCRIPTION OF DRAWING(S) - The drawing shows the surface metal phase diagram after sintering graphite iron-based powder metallurgy material.
