Anisotropic hardening in cold forging
, 2022 The goals of metal forming process design have long exceeded the mere shaping of components. Changes of the component properties which are caused by forming, including residual stresses, damage and work-hardening have received increasing attention in the last years.

Differences between traditional cold forging and cold orbital forging of a spur bevel gear
Procedia Engineering, 2017 Abstract Cold orbital forging, as an advanced incremental forming process, has been widely researched and used to fabricate the spur bevel gear. However, the mechanism of cold orbital forging is quite different from that of traditional cold forging, which leads to the different forming laws and different properties of forged gear. In this paper, cold
