Abstract: A method and apparatus for in-process transient spectroscopic analysis of a molten metal, wherein a probe (10) containing a pulsed high-power laser (14) producing a pulsed laser beam having a substantially triangular pulse waveshape is immersed in the molten metal and irradiates a representative quantity of the molten metal. The pulsed laser beam vaporizes a portion of the molten metal to produce a plasma plume having an elemental composition representative of the elemental composition of the molten metal. Before the plasma plume reaches thermal equilibrium shortly after termination of the laser pulse, a spectroscopic detector (241) in the probe (10) detects spectral line reversals, during a short first time window. Thereafter, when the afterglow plasma is in thermal equilibrium, a second spectroscopic detector (242) also in the probe (10) performs a second short time duration spectroscopic measurement. A rangefinder (22) measures and controls the distance between the molten metal surface and the pulsed laser (14).

Abstract: A process for producing a galvanneal layer on a steel substrate, including forming a Zn-Fe coating having a predetermined Fe content F (wt.%) on the steel substrate; and heat treating the Zn-Fe coating on the substrate from a predetermined starting temperature T1 (°C) to a predetermined ending temperature T2 (°C) at a predetermined heating rate R (°C/min.), wherein F, T1, T2, and R are selected so that the following condition is met, a.R?2 + b.T2¿ + c.R.F + d.R.T + e.R + f.T = g, where a, b, c, d, e, f and g are predetermined constants, thereby to form a virtually 100 % δ¿1? phase galvanneal structure. Alternatively, the heat treatment can be performed until the specimen temperature is just below a minimum temperature of the δ1 phase stability range at a selected Fe content and heating rate, followed by an isothermal hold for a predetermined time period until transformation to the δ1 phase occurs.

Abstract: A electrokinetic system (10) and method are provided for removing charged species from a sample (9) in which said charged species is commingled with at least one radionuclide. The apparatus comprises an anode compartment (11) comprising an anode (12), a cathode compartment (15) comprising a cathode (16), and a treatment zone (19) in fluid communication with the anode and cathode compartments (11, 15) for containing the sample (9). The anode compartment (11), cathode compartment (15), and treatment zone (19) are arranged so that a voltage gradient applied between the anode (12) and the cathode (16) induces an electrical current flow through the sample (9) in the treatment zone (19). The current causes migration of the positively charged species in the sample (9) toward the cathode (16) and the negatively charges species toward the anode (12). A pH controller is provided for monitoring and adjusting acidity and basicity. In carrying out the method of the present invention, a sample (9) of the contaminated waste to be treated is introduced into the treatment zone (19) of the electrokinetic system (10), a voltage gradient is applied between the anode (12) and the cathode (16), thereby inducing an electrical current flow through the sample (1); and monitoring and adjusting the pH of the system (10) to facilitate the removal of salts while maintaining contaminants within the sample (9).
