Influence that nanosecond electromagnetic pulses have on the acquisition of tin and the properties of its alloys
It is established experimentally that the influence that nanosecond electromagnetic pulses (NEMPs) have on the charge melt during the carbothermic reduction of cassiterite in the Na 2 CO 3 -NaNO 3 medium (1: 0.3) at t = 900–950°C accelerates the formation of the metal phase by a factor of ∼2 and aff...

= 900–950°C accelerates the formation of the metal phase by a factor of ∼2 and affects its composition. As the duration of irradiation increases to 30 min, the tin content in the crude alloy increases to ∼95%. The influence that the NEMP treatment of the bronze melt has on its physicomechanical properties is revealed. It is shown that the influence of pulses for 10–15-min increases the alloy density to 8.92 g/cm
