Effect of initial temper on mechanical properties of creep-aged Al-Cu-Li alloy AA2050
MATEC Web of Conferences, 2018 The evolution of mechanical properties of a third generation Al-Cu-Li alloy, AA2050, with different initial tempers (T34 and as-quenched (WQ)) during creep-ageing has been investigated and analysed in this study. A set of creep-ageing tests under 150 MPa

Springback Prediction of Dieless Forming of AZM120 Sheet Metal Based on Constitutive Model
Metals, 2020 Springback control is a key issue of the sheet-metal-forming process. In this paper, the mechanism of sheet-metal-forming along the folding trajectory of the computer numerical control (CNC) four-side automatic panel bender was studied, based on the bend-

Electrohydraulic sheet metal forming with flexible tools
MATEC Web of Conferences, 2018 In cold metal forming usually a die and a punch are required to form sheet metal in the desired shape. These two parts of the tool need to be produced of hardened materials in high precision.

EXPERIMENTAL EVALUATION OF DRAW BEAD COEFFICIENT OF FRICTION
Acta Metallurgica Slovaca, 2017 In this paper the results of both friction coefficient and springback testing using a drawbead test are presented. Deep drawing quality steel sheet (DC04 according to EN 10130:2009 standard) was used as the test material.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1989 The forming limit of sheet metals is examined in terms of the uniqueness of the solution. There are two cases indicating multiplicity, one is statically admissible and another is kinematically admissible. The multiplicities are considered to correspond to plastic instabilities.

The Use of Non-Edible Green Oils to Lubricate DC04 Steel Sheets in Sheet Metal Forming Process
Lubricants, 2022 Lubrication is a basic and relatively effective way to reduce friction in sheet metal forming operations. The drive to eliminate synthetic and mineral oils, which are difficult to recycle, from the manufacturing process has opened up opportunities for ...
