A new kind of magnesium alloys has been synthesized by high energy ball-milling of Mg and Fe mixed powders.Due to the high corrosion speed and reacting efficiency,the alloys are generally called super-corroding alloys.A SCA bulk is fabricated through cold-pressing and sintering the mechanically alloyed Mg-Fe powders.The chemical reaction of SCA with seawater rapidly releases heat and hydrogen gas,which may play very important roles in many ocean applications.For example,the reaction heat can be used to keep diver clothes warm;SCA corrosive links with the function of self-destruction can be utilized to control the sinking and floating of sonobuoy, and to salvage the training torpedo or other instruments.In addition,the reaction heat of SCA can be applied to heat food,machinery and ice or snow,which is thus very helpful for mountaineers.
