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.

超腐蚀合金采用Mg和Fe混合粉末，经高能球磨机械合金化、冷压、烧结，形成Mg-Fe合金块体，具有很高的海水腐蚀速率和反应效率，该合金化学反应放出的热量和氢气可在海洋工程中发挥重要作用，例如：可为深海作业潜水衣的保暖提供热量；由其制造的腐蚀链通过自毁机制，可用来控制声纳浮标的沉浮时间，打捞和回收水中的贵重仪器、装置以及训练用的靶雷；在偏远地区和寒冷地带，利用该合金的反应放热特性，不仅可加热机械、仪表或食品，而且能为登山运动员提供取暖所需的热量。
