摘　　要：对压制成型Φ20mm×10mm高聚物粘结炸药PBX03试样进行了50℃条件下累积9天的热处理试验,采用超声波特性参量检测了热处理试样,获得了PBX03试样热处理作用及机理的新认识:PBX03试样的超声波增益和声速值在热处理过程中均呈现出趋同的特征;适当的热处理有助于改善PBX03压制件内部质量的一致性;PBX03中TATB的不可逆长大可能是前述结果的主要致因。The heat treatment of polymer bonded explosive PBX-03 with φ20 mm × 10 mm was carried out at 50 ℃, and was characterized by ultrasonic characteristic value. Some new information about the effect and mechanism of heat treatment on PBX-03 was obtained. The results show that the ultrasonic characteristic values of the specimens display a unified tendency during the heat treatment,and the adequate heat treatment is helpful to improve the internal quality of PBX-03,and the irreversible growth of TATB in PBX-03 is probably thc main reason causing the results above.
