This melt-cast explosive shares comparable explosive properties to those of COMP B explosives and is melt-pourable and castable under conditions comparable to those of COMP B explosives, but experiences less impact, shock, and thermal sensitivity and avoids the issues of toxicity associated with COM

This melt-cast explosive shares comparable explosive properties to those of COMP B explosives and is melt-pourable and castable under conditions comparable to those of COMP B explosives, but experiences less impact, shock, and thermal sensitivity and avoids the issues of toxicity associated with COMP B. A fundamental and well-accepted component of COMP B, i.e., trinitrotoluene (TNT), is replaced with one or more mononitro-substituted or dinitro-substituted melt-cast binders, such as dinitroanisole, which can be melt cast without presenting the toxicity drawbacks experienced with the use of TNT. The melt-cast binder can also be combined with a processing aid selected from the group consisting of alkylnitroanilines and arylnitroanilines. Preferably, the composition also includes coarse oxidizer particles and energetic filler in fine particulate form.

A method according to claim 1, wherein said inductive member comprises a ferrite core or a silicon steel sheet. 7. A method of hardening a crankshaft having a hole, comprising the steps of: inserting an inductive member covered with an electrically insulating member into a plurality of oil holes defined in each of at least pins and journals of a crankshaft such that the inductive member is loosely fitted in the oil hole; effecting induction hardening on each of at least the pins and the journals while said inductive member is being held in said oil hole by a holder member of an electrically conductive material which engages in an opening of said oil hole, thereby producing a treated layer in said oil hole; quenching said workpiece and said hole by cooling said treated layer to produce a hardened layer; and removing said inductive member, said electrically insulating member, and said holder member from said oil hole.
