The variation in surface microrelief of the aluminum-lithium alloy Al-2% Li-2.5% Cu and pure aluminum as a result of irradiation by powerful pulsed hydrogen-plasma fluxes at heat-flux densities of 105-5·106 W·cm-2 and pulse length 20 μsec is investigated on a Desna unit. The minimum heat-flux density from the high-temperature plasma required to initiate surface melting of aluminum materials is determined. The temperature and corresponding vaporization rate from the sample surface are estimated for several characteristic heat-flux densities.
