Turbine Disk Forging Process Optimization
Volume 1: 25th Design Automation Conference, 1999Abstract This paper addresses one of the important aspects of the turbine disk forging process — the design of die geometry to achieve near-net-shape forging. The problem is formulated as a parametric geometry and high-fidelity analysis based optimization problem.

Evaluation of Forging Process Induced Residual Stress in Aluminum Die Forgings
Heat Treating Conference, 2021Abstract Forging processes include various steps to attain favorable material properties such as heat treatment, rapid quench, cold work stress relieving, and artificial aging. These steps, however, also contribute to bulk residual stress.

Claw-Pole Closed Forging Process
Advanced Materials Research, 2014Aimed at the present domestic problems in the forging process of claw pole, such as insufficient corner filling, excessive forming force and short life of dies. On the basis of the analyzing in the claw pole, a new process named the closed hot die forging, direct extrusion process of claw pole is constituted.

Analysis of forging defects for selected industrial die forging processes
Engineering Failure Analysis, 2016Abstract The main goal of this paper is to identify defects in forgings in selected die forging processes. The major problem is the formation of underfills due to air pockets between the forging and the tool. In the literature there is no information about modeling of such defects using FEM software, therefore, attempts were made to build numerical ...

Upper bound analysis of forging penetration in a radial forging process
International Journal of Mechanical Sciences, 2015Abstract A theoretical model based on upper bound approach is proposed to study forging penetration in a radial forging process. Using the transformations for both the geometric coordinate system and the velocity field, the parabolic discontinuity boundaries in axisymmetric problem are mapped into straight lines in the transformed field. As a result,

MOLYBDENUM FORGING PROCESS DEVELOPMENT
1963Abstract : The main effort on Phase IV to date has been directed towards arriving at a forging design suitable for use on the balance of the program. A search for such a forging and a review of prints received as a result of earlier inquiries were not rewarding in that no shapes were found which were suitable without extensive modification.
