“…The SSFM process can also operate through stages, including the first cooling or solidifying the semisolid blank into a solid blank and then reheating and forming the solid blank with suitable dimensions according to the production demands [34][35][36]. The SSFM process combines the advantages of liquid casting forming and solid plastic forming, as it has excellent flow mobility in the material and high physical properties in the product, which is regarded as one of the most potential green forming technologies [37][38][39]. As one of the important force transmission parts for the internal combustion engine, the connecting rod is often machined and manufactured with steel, cast iron, iron-based powder, and other materials [14][15][16][17].…”

As an important piece of equipment for hydrogen energy application, the hydrogen internal combustion engine is helpful for the realization of zero carbon emissions, where the aluminum connecting rod is one of the key core components. A semi-solid forging forming process for the 7075 aluminum alloy connecting rod is proposed in this work. The influence of process parameters, such as the forging ratio, sustaining temperature, and duration time, on the microstructures of the semi-solid blank is experimentally investigated. The macroscopic morphology, metallographic structure, and physical properties of the connecting-rod parts are analyzed. Reasonable process parameters for preparing the semi-solid blank are obtained from the experimental results. Under the reasonable parameters, the average grain size is 41.48~42.57 μm, and the average shape factor is 0.80~0.81. The yield strength and tensile strength improvement ratio of the connecting rod produced by the proposed process are 47.07% and 20.89%, respectively.
