Physical Modelling of Cross-Wedge Rolling of Ball Studs [PDF]

Archives of Metallurgy and Materials
The publication presents and reviews the results of a physical modelling study of the Cross Wedge Rolling process of ball-studs. The ball-studs was formed in a double system from C45 steel at 1050°C, while the physical modelling process was performed on ...

Novel damage calibration test based on cross-wedge rolling

Journal of Materials Research and Technology, 2021
This article presents a new calibration test for damage functions that uses the cross-wedge rolling method (CWR). In this test, the forming conditions were altered by applying wedges with decreasing forming angle on conical-cylindrical samples.

Study on the spiral microstructure defect of workpiece with a small area reduction formed via cross wedge rolling

工程科学学报, 2018
Local deformation of workpieces is a main process characteristic of cross wedge rolling; thus, it is difficult to cross wedge rolling the workpiece with a small area reduction owing to the weak ability to flow in the axial direction and the significant ...

A Machine Vision-Based Method for Detecting Surface Hollow Defect of Hot-State Shaft in Cross Wedge Rolling

Metals, 2022
In order to solve the problems of low detection efficiency and safety of artificial surface defects in hot-state cross wedge rolling shaft production line, a machine vision-based method for detecting surface hollow defect of hot-state shafts is proposed.

Numerical simulations of screw spike, worm and gear rolling [PDF]

, 2010
Cross wedge rolling (CWR) is a very efficient technological process which has a favourable effect on properties of rolled products. At the same time, however, this forming technique causes complex non-linear problems resulting from variable contact ...

Multimodal Mechanical Testing of Additively Manufactured Ti6Al4V Lattice Structures: Compression, Bending, and Fatigue

Advanced Engineering Materials, EarlyView.
In this experimental study, the mechanical properties of additively manufactured Ti‐6Al‐4V lattice structures of different geometries are characterized using compression, four point bending and fatigue testing. While TPMS designs show superior fatigue resistance, SplitP and Honeycomb lattice structures combine high stiffness and strength. The resulting
