✦ Synopsis

We report observations oT.a chemical reaction on a 100 ns rime scale in a nickel-aluminum powder mixurr while under high-pressure shock loading OpGcal pyrometer measurememx show values of spectral radiance thal can only be explained by high remperatures due Lo an enothermic reacrion. Srrealr photography shows spatial evolulion of rhe reaction zone in regions OC thr sample predicted IO experience shock pressures and temperatures known Lo initiate formation of nickel-aluminum alloys.
