Manufacturing Processes for Roll Bonded Titanium Alloy Structural Sections.

摘要

The roll diffusion bonding manufacturing process program has resulted in the successful fabrication of a closed section airfoil shape. The airfoil is typical of jet engine inlet guide vanes,compressor stator blades and helicopter rotor blades. The airfoil shape fabricated was found to have excellent bonds,uniform fillets between component members and excellent dimensional accuracy. The deviation between design and actual airfoil thickness measurements ranged from 0.001inch to 0.010inches. A mechanical property evaluation program was conducted comparing the properties of as-received material,as-rolled parent material containing no joint and as-rolled bonded material. (Author)
