The Hugoniot equation-of-state(EOS)of porous iron with an average initial density of 6.904g/cm^(3) has been measured in the pressure range from 90 to 160GPa,and a good straight fitting D=2.997+1.603u has accordingly been obtained,where D is the shock wave velocity and u the particle velocity,both in units of km/*** this with the Hugoniot EOS of non-porous iron,the Grüneisen EOS and the Rankine-Hugoniot energy conservation relation,and taking the possible solid-liquid transition correction,we have calculated the Grüneisen parameterγof iron and obtained the resultγ0ρ0=γρ=const,withγ0=1.945 andρ0=7.856g/cm^(3),ρbeing the density.

Innovative pulsed current-assisted multi-pass rolling tests were conducted on a 12-roll mill during the rolling deformation processing of SUS304 ultra-thin *** results show that in the first rolling pass,the rolling reduction rate of a conventionally rolled sample(at room temperature)is 33.8%,which can be increased to 41.5%by pulsed current-assisted rolling,enabling the formation of an ultra-thin strip with a size of 67.3μm in only one rolling *** three passes of pulsed current-assisted rolling,the thickness of the ultra-thin strip can be further reduced to 51.7μ*** clearly compare the effects of a pulsed current on the microstructure and mechanical response of the ultra-thin strip,ultra-thin strips with nearly the same thickness reduction were *** was found that pulsed current can reduce the degree of work-hardening of the rolled samples by promoting dislocation detachment,reducing the density of stacking faults,inhibiting martensitic phase transformation,and shortening the total length of grain *** a result,the ductility of ultra-thin strips can be effectively restored to approximately 16.3%while maintaining a high tensile strength of 1118 ***,pulsed current-assisted rolling deformation shows great potential for the formation of ultra-thin strips with a combination of high strength and ductility.

Sound velocities in shock-loaded solids are not only important to determine bulk moduli of solids at high pressures, but are also crucial to inform the shock melting of solids upon loading. In this letter, we first report on shock melting of porous solids at high pressures by measuring sound velocities in the porous iron of average density 6.90 g/cm^(3) in the pressure range of 110-180 GPa. The measured sound velocity softens at pressures from 122 to 156 Gpa, which may be attributed to shock melting of the porous iron.
