Highly reliable packaging interlayer materials are essential for utilizing the benefits of wide band-gap power devices. In this study, a two-dimensional mesh structure of Cu-10Ni (wt.%) alloy skeleton-reinforced SAC305 (Sn-3.0Ag-0.5Cu, wt.%) solder was employed to create solid-liquid interdiffusion (SLID) bonding connections on a Cu substrate at 250 °C and 0.03 MPa auxiliary pressure. The microstructural evolution and the mechanical property strengthening mechanisms of bonded joints with different composite solders were investigated. Due to the addition of Cu-10Ni alloy skeleton, the Cu-Ni atoms diffused into the Sn melt and acted as heterogeneous nucleation sites, contributing to the rapid nucleation and growth of (Cu,Ni)6Sn5 grains. The incorporation of Ni inhibited the merging and coarsening of intermetallic compound (IMC) grains, and the joint was composed of fine-grained (Cu,Ni)6Sn5 phase and interspersed Cu10Ni skeleton. Shear strength of the joint at soldering time 210 s reached 47.75 MPa, marking a 104.58% enhancement compared to the pristine SAC305 solder joint. The influence of grain refinement on the mechanical properties of the joint was discussed based on the Hall–Petch relationship. The grain boundary strengthening effect synergized with the toughening effect of the alloy skeleton, ultimately achieving highly reliable joints. © 2023, The Authors. All rights reserved.

High-carbon steel consisting of soft ferrite and hard cementite is susceptible to micro-defects owing to the mismatched deformation between the ferrite and cementite during cold forming, which seriously deteriorates the fatigue life. However, the investigation of the damage and failure behavior in high-carbon steel during cold deformation remains largely undisclosed, which hinders further control of the microstructure and forming process. The current work investigates the damage evolution and fracture behavior related to the microstructural characteristics of spheroidized ferrite-cementite steel. A multiscale modeling framework is presented by coupling macroscale finite element (FE) simulation, mesoscale representative volume element (RVE) modeling, and nanoscale molecular dynamics (MD) simulation to analyze largescale plastic deformation and damage characteristics. In particular, the Gurson-Tvergaard-Needleman (GTN) damage model is used to predict the fracture behavior of the macroscale FE model. The uncoupled Rice-Tracy law and the maximum principal stress criterion are utilized to simulate the mesoscale damage behavior. The cohesive zone model (CZM) in the form of B-K constitutive law is utilized to simulate the interfacial decohesion. The GTN model parameters are evaluated by the response surface method (RSM). The nanoscale molecular dynamics simulations are conducted to obtain matrix-particle interface strength properties under the mixed loading. The mechanical property of ferrite phase was calibrated by the inverse analysis method based on genetic algorithm (GA). The failure model parameters of two phases are identified by DIC test results. The macroscale simulations accurately predict damage and fracture behavior of high-carbon steel. The results show that the voids preferentially initiate at the two-phase interface with the smallest spacing between particles. Subsequently, voids grow along the boundary of the cementite particles and then coalesce to form a c
