Compression of Bimetallic Components – Analytical and Experimental Investigation

Present paper elaborates cold upsetting of dual‐material component which consists of an outer ring and inner solid cylinder. Assembly is compressed by parallel flat dies. Outer ring is of mild steel C45 and inner core of softer C15 steel. Process has been analyzed analytically and experimentally. Analytical analysis was performed by slab method by introducing appropriate assumptions and boundary conditions. Two different analytical models have been considered. In the experimental work assembly of two different materials, outer ring (C45E) and inner cylinder (C15E), was compressed to different heights. During the process, forming load was recorded. Results have shown reasonable agreement between analytical prediction and experimental measurements.
