Abstract

The work aims to utilize laser heat treatment combined with ultrasonic rolling technology to explore the influence on the surface properties of the 4J32 invar alloy, so as to improve the surface integrity of the 4J32 Invar alloy and enhance its surface service performance. Through single-factor variable strengthening experiments, the effects of static pressure, ultrasonic amplitude, and rolling passes on the surface roughness, plastic deformation depth, and surface microhardness of the samples were investigated. The rolling parameters significantly influenced the surface roughness, depth of the grain refinement layer, and surface microhardness of the material. When the ultrasonic amplitude was set to 7 μm, the static pressure to 1 300 N, and the rolling passes to 6, the surface roughness reached a minimum value of 0.148 μm, a 64.4% reduction compared with the unrolled samples. The depth of the grain refinement layer reached a maximum of 144 μm when the ultrasonic amplitude was set to 7 μm, the static pressure to 1 300 N, and the rolling passes to 10. An excessive static pressure could lead to lattice distortion, affecting the depth of the grain refinement layer. After ultrasonic rolling treatment, a work-hardened layer was formed on the material surface. The surface microhardness increased with the increase of the rolling force, but an excessively large ultrasonic amplitude negatively impacted the surface microhardness. Under optimal conditions (1 300 N static pressure, 7 μm ultrasonic amplitude, 8 passes), the surface microhardness reached 241.7HV0.1, which was an 89.3% increase compared with the unrolled samples. Grain refinement is achieved through dislocation movement and stacking fault mechanisms by ultrasonic rolling treatment, thereby contributing to strength and work hardening capability, and effectively improving the surface integrity of Invar alloy, providing an important research foundation for its surface strengthening.
