Noticing that strong exothermic reaction due to large negative enthalpy of mixing can occur among major components of ti - zr - based quasicrystal alloy systems and zr - based bulk amorphous alloy systems, we developed for the first time a new technique for fabricating both ti - zr - ni systems quasicrystal materials and zr - al - ni - cu systems amorphous - based composite materials using laser - induced self - propagating reaction synthesis ( lsrs )
注意到構成ti - zr基準晶合金體系和zr基大塊非晶合金體系的主要組元之間具有很大的負混合焓，因而能夠發生很強的放熱反應。利用這一特點，我們首次開展了激光誘導自蔓延反應合成ti - zr - ni系準晶材料和zr - al - ni - cu系非晶復合材料的探索研究。 -
During the course of ball milling, there was a rise of temperature, which accord with the value of theory well and proved that there was a exothermic reaction which happened suddenly and completed soon. this ball milling reaction was a sudden and fast self - propagating reaction, not a gradually diffusing reaction
在球磨過程中，檢測到有溫度突然升高的現象，而且與理論計算值符合很好，可以證明球磨時存在一個突然發生、瞬間完成的放熱反應；該球磨反應的是一個突然爆發的自蔓延反應，是瞬間合成過程，而不是一個逐漸擴散的反應過程。 -
3, considering of the combustion reaction controlled by multi - mechanism, calculated results showed combustion wave of the continual combustion also changed to an unstable combustion way, the combustion temperature and wave propagating velocity changed periodically. by changing factors about the reaction mechanism, results showed the periodic oscillation combustion was mainly caused by the effect and feedback between chemical reaction and thermal conduction
3 、計算結果同時顯示， shs燃燒過程中的不穩定主要來源於燃燒過程的熱反饋造成的化學反應機理變化，在這種存在多機理控制的反應體系中，燃燒過程的溫度會隨時間變化而出現有規律的振蕩。 -
