具有共价键/离子键的硬脆固体广泛用于现代制造技术中。优化成形工艺可以缩短制造时间和部件生产成本，同时延长部件寿命。相同的过程可能会导致使用中的磨损和疲劳退化。这类固体的先进整理协议的教育发展需要从材料科学的角度全面了解小规模接触的损伤机制。本文综述了压痕应力场脆韧转变的基本原理，并对轴向载荷和滑动载荷以及钝接触和锐接触进行了区分。在脆性和韧性加工和严重和轻度磨损的背景下，微接触过程中伴随的变形和去除机制进行了分析和讨论。材料的微观结构在材料去除模式的核心作用。
Hard and brittle solids with covalent/ionic bonding are used in a wide range of modern-day manufacturing technologies. Optimization of a shaping process can shorten manufacturing time and cost of component production, and at the same time extend component longevity. The same process may contribute to wear and fatigue degradation in service. Educated development of advanced finishing protocols for this class of solids requires a comprehensive understanding of damage mechanisms at small-scale contacts from a materials science perspective. In this article the fundamentals of brittle–ductile transitions in indentation stress fields are surveyed, with distinctions between axial and sliding loading and blunt and sharp contacts. Attendant deformation and removal mechanisms in microcontact processes are analyzed and discussed in the context of brittle and ductile machining and severe and mild wear. The central role of material microstructure in material removal modes is demonstrated.
