The cold precision forging processes of a multi-row sprocket are still in the experimental stage because of the complicated processing conditions.
At present, spur bevel gears are mainly processed by forging, showing advantages of high processing efficiency, low processing cost and fine microstructure material.
With respect to the wrought processing of γ-TiAl alloys, the hot forging processes for ingot-breakdown is one of the most important steps.
Microstructure evolution, tensile and creep properties of designing bimodal size lamellar O phases by thermo-mechanical processing including conventional forging, isothermal forging process and heat treatment for Ti 22Al 25Nb (at%) orthorhombic alloy were investigated.
A hot forging process of an as-cast NiTi shape memory alloy was designed by processing maps and a finite element method analysis.
Due to limitations in forming speeds, tooling strength and narrow processing windows, complex thin-walled parts cannot be made by traditional warm drawing or hot forging processes.
The post processing like forging, rolling, extrusion of these composites further improves their properties in addition to the confirmation to the final shape and size.
Design and control of microstructure of engineering parts made from nickel based superalloys with superior mechanical properties for high temperature applications, require the parts to be subjected to certain thermo-mechanical processing during forging.
It includes atomic and molecular interactions and structures, synthetic chemistry, phase equilibria and phase diagrams, a variety of characterization methods, mechanical testing and fracture mechanics, visco-elasticity, rheology, materials processing from forging through sintering to injection molding, as well as prepreg making and composite manufacturing.
