讨论了使用标准维氏显微硬度计研究聚合物材料显微硬度的一些其他可能性。提出了两种新的研究方法：确定载荷作用下的压痕尺寸和获得穿透曲线。它们的优势和前景，特别是与标准方法相结合，已经在非聚合物和不同聚合物(塑料和弹性)材料上得到了展示。根据获得的附加信息，可以得出一些关于结构和物理力学性能的新的、更精确的结论。所提出的方法似乎特别适合于研究聚合物和复合材料的特定超分子结构，以及主要影响表层或非晶相的过程和结构变化，如老化、化学和物理修饰、辐射等。
Some additional possibilities for microhardness investigations of polymer materials using a standard Vickers microhardness device are discussed. Two new investigation methods have been suggested: determining the impression size under a load; obtaining penetration curves. Their advantages and prospects, especially in combination with standard methods, have been demonstrated on non-polymer and different polymer (plastic and elastic) materials. On the basis of the additional information obtained, some new and more precise conclusions concerning structure and physico-mechanical properties can be drawn. The proposed methods seem to be particularly appropriate for studying specific supermolecular structures of polymers and composite materials as well as processes and structural changes affecting predominantly surface layers or amorphous phase, for example ageing, chemical and physical modification, irradiation, etc.
