Summary

Shock induced reactions in the Ni-Al and Mo-Si systems are experimentally investigated with consideration of the pretreatment effect on the shock reactivity. The milling-type and the repeated-forging type mechanical alloying (MA) procedures were first used to reduce the elemental powder size from micron to submicron and further to yield nano-structured solid solution by varying the processing time. These pretreated powders were consolidated by uniaxial pressing into a powder compact, which was employed as a sample for shock synthesis. With comparison to thermally-ignited and mechanically-ignited SHS and shock reactive synthesis from elemental powder mixture, reaction mechanism of shock induced reactions is considered to make advancement in shock chemistry for processing of refractory metal aluminides and silicides.
