美国华特弗利特兵工厂以前的研究发现,热导率是对炮管烧蚀速度影响较大的材料性能之一。热导率的很小变化就会引起钢的烧蚀速度产生很大变化。为了改变热导率,对炮钢(SAE4330钢的变型)材料的成分做了少许调整,减少含硅量同时相应地增加含钼量,结果使烧蚀速度产生了很有利的变化。烧蚀速度全 A previous study by the Walter Arsenal in the United States found that thermal conductivity is one of the material properties that greatly affects barrel ablation speed. Small changes in thermal conductivity can cause significant changes in the rate of steel ablation. In order to change the thermal conductivity, a slight adjustment was made to the composition of the material of the gun steel (variant SAE4330) to reduce the amount of silicon and to increase the amount of molybdenum accordingly, resulting in a very favorable change in the rate of ablation. Ablation rate full
