摘要
Thermal explosion (ignition) of various Ni-Al samples - such as powder blends, rolled and magnetron sputtered films, compacts of mechanically activated and non-activated mixtures - was explored with special emphasis on the role of mechanical activation. The critical ignition temperature (T c) was found to diminish from 650 C for starting (non-activated) Ni-Al mixtures down to 280 C for properly activated samples. For the thin films of alternating Ni and Al layers prepared by magnetron sputtering, T c turned out to be as low as 230 C. © 2013 Allerton Press, Inc.
