Analysis, Validation and Optimization of the Multi-Stage Sequential Wiredrawing Process of EN AW-1370 Aluminium

open access: yesMetals, 2019
For the wiredrawing of aluminium, the initial wire rod is obtained by continuous inverted casting. The raw geometry is industrially processed in a linear multi-step wiredrawing sequence to obtain a wire that is commonly used for the manufacture of ...

Analysis of Forming Behavior in Cold Forging of AISI 1010 Steel Using Artificial Neural Network

open access: yes, 2020
Cold forged parts are mainly employed in automotive and aerospace assemblies, and strength plays an essential role in such applications. Backward extrusion is one such process in cold forging for the production of axisymmetrical cup-like parts, which is ...

Ecological lubrication in cold forming of sintered powder metallurgical components [PDF]

open access: yes, 2018
In this contribution a new lubrication approach for cold bulk metal forming is presented. By exploiting the process-related porosity of pm components as a lubricant storage, the resulting pressure of a forming process forces the stored oil to leak out ...

Probing the potential of structured and surface functionalized tools for dry cold forging of aluminium

open access: yesMATEC Web of Conferences, 2018
In order to reduce friction and wear in cold forging of aluminium and its alloys a tremendous amount of lubricants is used. The main task of the liquid lubricants is the separation of tool and workpiece surfaces to avoid adhesion and abrasion.

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

open access: yesFEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...
