Shock heating can cause temperature rise prior to the porous liner collapse process because of its porous nature, which is possible to increase the jet temperature and enhance the jet ductility. The temperature rise calculation method was presented, and the porous effect on the jet behavior was studied with the pulse X-ray photograph. It was shown that the jet ductility increased with the initial porosity within some value, and the jet diameter became smaller with increasing initial porosity.
