Historiographical studies were carried out to clarify the regional origin and establish the dating periods of the Persian Shamshir blade. It was revealed that every section of the Persian Shamshir blade consists of damask surface areas having different macrostructure. The damask surface in the forte resembles the highest-grade Taban Damascus steel, the pattern of the middle section of the blade is typical of a medium-grade Kum Hindi steel, and the foible pattern corresponds to the lowest quality Sham steel. The features of carbide banding in the longitudinal and transverse directions were studied. It was determined that the damascene structure comprises a regular layered morphology of carbide banding of score 4 of inhomogeneity. It was concluded that the width ratio of the troostite sections to the carbide layers obeys the golden ratio rule (61.8%:38.2%). It was established that the main background of the damascene structure of the 17th-century saber blade Shamshir is the matrix phase of lamellar troostite, with a volume fraction of 78%, and the excess phase of pebble-type cementite carbide, with a volume fraction of at least 85%.

进行了史学研究，以澄清波斯沙姆希尔刀片的区域起源并确定年代。据透露，波斯沙姆希尔刀片的每个部分都由具有不同宏观结构的锦缎表面区域组成。长处的锦缎表面类似于最高等级的塔班大马士革钢，刀片中间部分的图案是典型的中等级库姆印地钢，而弱点图案对应于最低质量的沙姆钢。研究了碳化物带状碳化物在纵向和横向上的特征。确定镶嵌结构包含不均匀性分数为4的碳化物带的规则层状形态。结果表明，屈氏体截面与碳化物层的宽度比服从黄金比例规则（61.8%：38.2%）。确定17世纪Shamshir军刀镶嵌结构的主要背景为层状屈氏体基体相，体积分数为78%，剩余相为卵石型渗碳体碳化物，体积分数至少 85%。
