The Effects of Forming Parameters on the Single Point Incremental Forming of 1050 Aluminum Alloy Sheet
The single point incremental forming (SPIF) is one of the dieless forming processes which is widely used in the sheet metal forming. The correct selection of the SPIF parameters influences the formability and quality of the product. In the present study, the Gurson-Tvergaard Needleman (GTN) damage model was used for the fracture prediction in the numerical simulation of the SPIF process of alum...
متن کاملLow-Carbon Steel Sheet Asymmetric Single-Point Incremental Forming: Analysis and Optimization of the Surface Roughness (TECHNICAL NOTE)
Surface roughness (SR) has an adverse effect on the appearance of low-carbon steel parts, formed in the asymmetric incremental sheet forming (AISF) process, particularly those requiring painting operation. The purpose of this study is to investigate the effects of AISF process parameters on the surface roughness of an asymmetric part formed on low-carbon steel sheets. The parameters are feed ra...
متن کاملInvestigation of Fracture Depth of Al/Cu Bimetallic Sheet in Single Point Incremental Forming Process
Single point incremental sheet forming (SPISF) has demonstrated significant potential to form complex sheet metal parts without using component-specific tools and is suitable for fabricating low-volume functional sheet metal parts economically. In the SPIF process, a ball nose tool moves along a predefined tool path to form the sheet. This work aims to optimize the formability and forming force...
متن کاملStrengthening Mechanisms in the Aged 2024 and 7075 Aluminium Alloys
Aluminum 2024 and 7075 alloys which are widely used in aerospace and marine applications were chosen to investigate their strengthening mechanisms. Using differential thermal analysis (DIA), metallography and tension tests, the best solutionizing conditions were determined to be 500±5°C and 2 hours for 2024 and 480?±5°C and 1 hour for 7075 alloy. Aging was performed in the range of 100 to 200°C...
متن کاملLocalised corrosion in aluminium alloy 2024-T3 using in situ TEM.
An approach to carry out chemical reactions using aggressive gases in situ in a transmission electron microscope (TEM), at ambient pressures of 1.5 bar using a windowed environmental cell, called a nanoreactor, is presented here. The nanoreactor coupled with a specially developed holder with platinum tubing permits the usage of aggressive chemicals like hydrochloric acid (HCl).
