Cryogenic Mechanical Properties and Cutting Surface Topography of SiCp/Al

Abstract

Abstract:

SiCp/Al is one of the key materials for lightweight manufacturing of large aerospace structural components. However, its multi-phase heterogeneous characteristics lead to severe machining damage and challenges in surface quality control. Tensile tests across a wide temperature range from -196 ℃ to 20 ℃ are conducted in this study, revealing the evolution of mechanical properties dominated by cryogenic strengthening effects in SiCp/Al materials. Comparative experimental studies on cryogenic and room-temperature milling are performed to analyze the macro- and micro-scale mechanisms by which cryogenic characteristics and process parameters influence cutting forces and surface topography. The results demonstrate that the material exhibits higher yield strength and tensile strength in cryogenic environments, while liquid nitrogen cooling medium reduces cutting temperature and weakens local thermal softening effects, resulting in higher milling forces compared to room-temperature machining. However, the enhanced interfacial strength under cryogenic cooling reduces the extent of surface pits and crack damage, producing better surface roughness than conventional processing. This paper provides a novel theoretical foundation and engineering basis for precision manufacturing of difficult-to-machine aerospace composites.

Key words: cryogenic cutting, SiCp/Al, mechanical property, surface topography
