Fracture split-type connecting rod, internal combustion engine, transportation apparatus, and production method for fracture split-type connecting rod

摘要

A connecting rod (1) is a fracture split-type connecting rod made of an ±+² type titanium alloy, including a rod main body (10) and a big end (30) provided at an end of the rod main body (10), the big end (30) being fracture-split. The structure of the rod main body (10) is an equiaxed ± structure, and the structure of fractured surfaces (A) of the big end (30) is an acicular ± structure.
