摘　　要：为论证非晶合金作为新型换能元的可行性,设计制作了桥丝式非晶合金换能元,采用DSC热分析方法研究构成组分对非晶合金材料释能效果的影响,通过实验探究了非晶合金桥丝换能元在恒定电流激发下的电热温度响应、电阻温度系数变化以及电容放电激发的电爆特性。结果表明,非晶合金是一种亚稳态的含能材料,在晶化过程中释放能量。桥丝式非晶合金换能元具有电阻负温特性,电阻相对变化率为6.38%,电热换能功率可提高17.5%,与电阻-温度线性变化的镍-铬桥丝换能元相比,表现出更优良的释能效果。研究初步论证了非晶合金作为新型换能元材料的可行性,为电火工品换能增效技术发展提供了新方案。In order to demonstrate the feasibility of amorphous alloy as a new type of micro‑heater material,the amorphous alloy bridge wire micro‑heater was designed and fabricated,and the influence of constituent components on the energy release effect of amorphous alloy material was studied by DSC thermal analysis.On this basis,the electrothermal temperature response,change in temperature coefficient of resistance and the electro‑explosive characteristics of the amorphous alloy bridge wire micro‑heater were investigated.Results show that the amorphous alloy is regarded as a metastable energetic material when it releases energy,and exhibits negative temperature coefficient of resistance during crystallization process,leading to that relative change in resistance is 6.38%,and the electrothermal energy transfer power is increased by 17.5%.Compared to the Ni‑Cr bridge wire micro‑heater with linear temperature coefficient of resistance,amorphous alloy bridge wire micro‑heater characterizes a better energy release effect.These preliminarily demonstrate the feasibility of amorphous alloy as a promising initiator micro‑heater material,and expand the approach on efficiency improvement of electrical initiator micro‑heater.
