摘      要：Besides a typical high‐density plasma source,electrical explosion of conductors is also indispensable in switches,nanomaterial synthesis,shock‐wave sources,*** this paper,an experimental study regarding plasma dynamics of electrical wire explosions(μs‐timescale)is presented,with spatiotemporal resolved *** Cu/Ni wire and Cu‐Ni alloy wire were used and *** alloy wire usually has a higher resistivity,resulting in a higher initial energy deposition(heating)*** inverse transformation indicated that the plasma radiation focussed on the outer region of the discharge channel for the alloy *** addition,the metallic vapour determined by the material properties had a considerable influence on the plasma process and resulting *** particular,both transverse and axial‐layered structures were observed in alloy wire *** addition,for the first time,the expanding arc‐like plasma of explosion products was understood and examined from aspects of material properties and energy *** later stage of wire explosion resembled the state of regular metal vapour arcs under 1 MPa ***,the core factor for the fast energy deposition stage of wire explosion was *** between pre‐exposition circuit parameters and post‐explosion dynamic effects were found,which is significant for practical applications.
