端面粘贴包覆火药界面粘结强度研究

包覆火药装药控制燃气生成速率，降低弹性温度系数，提高弹丸初速的效果部分来自于包覆层的作用，对预制包覆层端粘包覆火药，其包覆层的厚度，密度，强度等性能已根据弹道和装药表确控制，包覆层与基药的界面粘结度就决定了包覆层控制燃气生成速率的有效性和可靠性，它是检验端面粘贴包覆火药工艺质量的关键指标，本文采用落锤实实验检包覆火药的界面结强度，研究了粘结工艺条件对端面粘贴包覆火药界面粘结强度的影响，通过实验选择出了合适的粘结剂及粘结工艺条件，制备了界面粘结强度良好的端面粘贴包覆火药。

In‐line Rheological Behaviors of Gun Propellant Substitute Assisted with Supercritical CO2 in Extrusion Processing

To improve the rheological behaviors of gun propellants, SC‐CO₂ was injected into the gun propellant substitute in extrusion processing. A slit die rheometer was used to investigate the in‐line rheological behaviors of CA solution. A Power model was applied to describe the rheological behaviors of CA/SC‐CO₂ mixtures. The viscosity and pressure of CA solution obviously decrease with the assistance of SC‐CO₂. The viscosity of CA solution reduces by 16.64 % at 55 °C and 10 s⁻¹ with the presence of SC‐CO₂. Increasing the processing temperature makes the viscosity of CA/SC‐CO₂ mixture decrease remarkably, but it weakens the plasticization of SC‐CO₂ to CA. Although the increasing solvent content improves the flow of the CA/SC‐CO₂ mixture, it lowers the strength of CA/SC‐CO₂ mixture, which is not in favor of the quality of product. The investigation of the in‐line rheological behaviors of CA/SC‐CO₂ mixture is fundamental and important for the safe extrusion of gun propellants assisted with SC‐CO₂.

Processing of Composite Gun Tubes with GLEEM and Hammer Forging

Refractory metal liners have been shown to extend the service life of gun tubes a considerable amount. The major technical hurdle to date has been keeping the liners in place during firing. To address this problem, composite gun tubes made of steel and pure niobium have been fabricated through a combination of the GLEEM (gun liner emplacement with an elastomeric material) and the hammer forging. The three barrels made by this approach were test fired in single-shot and burst-fire mode. One of the barrels whose liner had been cold-sprayed with tungsten carbide particles before the GLEEM process showed no liner movement in any of the tests. The success of this new liner processing technology to prevent liner movement offers the potential for further investigations of refractory metals that are more suitable as liner materials.
