Design of hole-clinching process for joining of dissimilar materials – Al6061-T4 alloy with DP780 steel, hot-pressed 22MnB5 steel, and carbon fiber reinforced plastic
TL;DR: In this article, hole-clinching tools were designed based on the geometrical relationship between the forming volume and the joint strength, and practical experiments were performed to verify the practicality of the hole clinching process.

Design of hole-clinching process for joining CFRP and aluminum alloy sheet
TL;DR: In this paper, a hole-clinching process for joining carbon fiber reinforced plastic (CFRP) with an AA6061 alloy sheet was proposed, in which the AA60 61 alloy sheet is indented into a hole in the CFRP and interlocked via deformation of the AA 6061 alloy only.

On critical surface strain during hot forging of lubricated aluminum alloy
TL;DR: In this paper, the Coulomb friction coefficient was formulated as a function of temperature, pressure, and material strain, and optimized by minimizing the difference between the predicted and experimental results.

Development of L-sectioned ring for construction machines by profile ring rolling process
TL;DR: In this article, a profile ring rolling process for large-scale profile rings with an L-section for construction machine parts is developed. But the work is limited to a single pass to minimize the cycle time.
