中文摘要：研究模拟发射后不同速度段Cu-Cr-Zr合金轨道的损伤特性.采用XRD、XPS、EBSD、SEM、硬度测试、电化学测试和DSC等手段对合金样品的显微组织、形貌和性能进行研究.研究发现,在模拟发射样品表面形成了沉积层.沉积层的厚度和表面粗糙度随着热效应的增加而增加,表明电弧烧蚀损伤程度与发射速度的相关性.样品的硬度变化归因于沉积层和变形硬化的影响.表面沉积层影响样品的耐腐蚀性和结晶特性,从而导致后续服役性能发生变化.此外,样品的表面织构和塑性变形能力与再结晶程度和变形晶粒数量有关.

外文标题：Damage characteristics of Cu-Cr-Zr alloy rail of electromagnetic railgun after simulated launch

外文摘要：The damage characteristics of different speed sections of Cu-Cr-Zr alloy rail after simulated launch were studied.The microstructure,morphologies and properties of samples were investigated by using XRD,XPS,EBSD,SEM,hardness test,electrochemical test and DSC techniques.It was found that deposition layers were formed on the surfaces of the simulated launch samples.The thickness and surface roughness of these deposition layers increased with increasing the heat effect,suggesting a launch speed dependent damage degree of the arc ablation.The hardness variation of samples is attributed to the effects of the deposition layer and deformation hardening.The surface deposition layer affects corrosion resistance and crystalline characteristics,leading to changes in subsequent service performances.Additionally,the surface texture and plastic deformation ability of the samples are related to the recrystallization degree and deformation grain amount.
