This paper briefly introduces the principle of near net shape forming and technical characteristics of electrical additive manufacturing（EAM）. A preliminary study on the properties and characteristics of EAM08CrMo that is manufactured by EAM is carried out

which provides technological support for the application of EAM. By testing and analyzing the chemical composition

micro-structure and macro-mechanical properties of EAM08CrMo

it is verified that the properties of material manufactured by EAM

the macro-properties are well-distributed

without thickness effect and directionality. By testing and analyzing the changes of micro-structure and macro-mechanical properties of EAM08CrMo before and after thermal aging treatment

it is concluded that the effect of thermal aging treatment on microstructure and impact toughness is little

but the strength has a slightly decrease.
