Abstract

Product composition and combustion parameters for non-activated and mechanically activated Ti–Ni mixtures were explored as a function of preheating temperature T₀. Upon an increase in T₀, frontal combustion of activated blends was found to change to a mode of thermal explosion at T₀ around 190°С. Frontal combustion of non-activated blends was accompanied by local melting over the entire range of T₀. Our results may turn helpful in theoretical modeling of SHS reactions.

Ti-Ni系统中的机械活化SHS：预热温度的影响

摘要

研究了未活化和机械活化的Ti-Ni混合物的产物组成和燃烧参数，它们是预热温度T ₀的函数。随着T ₀的增加，发现活化混合物的正面燃烧在190°C附近的T ₀处转变为热爆炸模式。未活化混合物的正面燃烧伴随着在整个T ₀范围内的局部熔化。我们的结果可能有助于SHS反应的理论建模。
