Retrogression-reaging and hot forming of AA7075
The retrogression-reaging (RRA) and hot forming behavior of AA7075 were studied. AA7075 is a high-strength alloy used in applications where weight is of particular importance, such as in automobiles. Like many of the high-strength aluminum alloys, AA7075 requires elevated temperature forming to …

Nonlinear Finite Element Modeling and Analysis of Metal Hot Forming for Automotive Weight Reduction
… The developed methodology is applied to the forming process of a transmission clutch hub which is constructed from UHSS 22MnB5 for the purpose of automotive lightweighting. The entire process chain is considered, including the hot stamping process, in which a high temperature blank enters a …

A study of the forming limits of cold and hot forming of aluminium alloy sheets with multi-point tooling
Multi-point forming (MPF) is a special category of sheet metal forming techniques with good operational flexibilities due to using two sets of adjustable pins along the machine ram direction. These pins represent the acting points of the desired forming-tool surface contours. Although this …

Investigation of die wear by modelling the extrusion of Inconel 718
Die wear is always an important issue in hot forming processes, such as in forging and extrusion. Die life affects the economics of process to product and in order to optimise die life, the mechanism of wear should be approached scientifically. The aim of this work is to provide a systematic method …

Mathematical modelling of glass flow during a pressing operation.
… the behaviour of molten glass during a pressing (hot forming) operation. An outline of glass manufacturing is given in chapter 1, together with a discussion of the factors influencing the behaviour of the molten glass and the advantages of a mathematical model over direct experimentation. Chapter …

Segregation and embrittlement in metallic interfaces : bounds, models, and trends
… [1], wear resistance [2], and superplastic forming behavior [3], in addition to changes in many other properties. These materials are thus of technological interest as structural materials. However, the excess free energy associated with grain boundary formation drives rapid grain growth in …

Enhancing the Sustainability of Aluminium Production and Products
… Subsequent chapters shift the focus to the hot forming of 6xxx series aluminium alloys. Chapter 4 details lab-scale experiments on 6082.50 and two 6110 alloy variants, including finite element modelling and constitutive data generation. This approach demonstrated robust fits of the finite …
