Superplastic forming (SPF) commonly requires industrial presses with an integrated large furnace able to uniformly heat the tools and the blank. In this work the feasibility to form via SPF an automotive component using a different heating approach w

Development of a model for the simulation of laser surface heat treatments with use of a physical simulator

Nowadays, laser hardening is a sufficiently mature process to be industrially applied as a substitute for traditional heat treatments that are more expensive and less flexible. The bottleneck of the process is the difficulty in pre-determining the pr

In this work, the mechanical and technological behaviour of AZ31 magnesium alloy laser welded joints is investigated. The forming behaviour of the joints is analysed by both tensile and biaxial stretch tests. Each test is monitored using a digital im

A thermal model for laser hardening simulation

Laser hardening is a very flexible and useful process for surface treatment of medium carbon steels, capable of processing varied and complex geometries. In order to enlarge the range of industrial applications to which this process can be applied, a

Surface hardening with discrete laser spot treatment is an interesting solution since the adoption of a single pulse allows the treatment of different surface geometries avoiding the effect of back tempering. The aim of this work is to find a suitabl
