1 sty 2021 · In order to improve the geometrical and mechanical thread quality, the influences of the initial tool temperatures and the heat input induced during the forming processes are analyzed within this paper.
24 cze 2024 · The model encompasses fluid flow, heat transfer, and solidification. The study identifies the optimal combination for flow field, temperature distribution, and equiaxed grain ratio within the specified parameter range at a casting speed of 4.0 m/min and a superheat of 40 °C.
13 sty 2021 · The aim of this study is to investigate mechanical and microstructural properties of 2024 aluminium tubes (2024 AA) which are produced by flow forming technique and make comparisons between the flow formed 2024 AA, full annealed (2024-O) and solution heat treated...
As its name describes, this advanced metalworking process forces the material to “flow” into the desired shape. In addition, flow forming starts with a machined, forged, or deep-drawn tube or cup-shaped “preform” that is much thicker than the thin circular disk found in spin forming operations.
9 lip 2019 · This paper mainly concerns the thermo-mechanical analysis to evaluate the process parameters in the hot press forming with the 22MnB5 sheet such as the austenitization temperature, transport and quenching time for enhancing the efficiency in the production cycle.
Material Properties in Metal Forming. Desirable material properties: Low yield strength and high ductility. These properties are affected by temperature: Ductility increases and yield strength decreases when work temperature is raised. Other factors: Strain rate and friction.
1 sty 2019 · The flow drilling technology and subsequent thread forming represents an economical and technically interesting manufacturing alternative. With Flow drilling, a bush is generated by a...
