Solid-state recycling is a direct conversion method for producing metal chips, whereas the
materials are plastically deformed into the final product without melting, offering lower …

This study aimed to explore the evolution of flow lines and microstructures of M50-steel
bearing ring and the anisotropy of its tensile mechanical properties after Multi-Stage Hot …

A multi-stage cold forging process was developed and complemented with finite element
analysis (FEA) to manufacture a high-strength one-body input shaft with a long length body …

The core of railway turnout is generally cast from high manganese steel, but the casting
turnout core will produce porosity, cracks, and other casting defects. By analyzing the …

This work is motivated by the fact that friction has a significant impact on the microstructures
of titanium forged parts, further influencing their mechanical properties. In this paper, a 3D …

Parametric investigations related to shoulder angle on tool geometry for a combined cold
extrusion of a drive shaft, which consisted of spur gear and internal spline structures, were …

This study evaluated dry-in-place lubricants used for cold forging. A group of isothermal
compression tests with a strain rate (ε˙) range of 0.001–1 s− 1 and temperature (T) range of …

Abstract Development of cracks along the center axis of large high strength steel bars
commonly occurs during the forging and leads to excessive part rejections. The present …

The formation of hot forging-upsetting finishing-radial extrusion (HF-UF-RE) compound into
conjunction gears is an innovative process. This study describes the most existing …

The article discusses the possibilities of introducing selected aspects and problems in the
robotization of the workstation in the hot die forging process, the production of the yoke …
