通过开发具有更高强度、韧性和导热性的高性能铝合金，Constellium挤压件在汽车轻量化领域处于领先地位。该公司目前正在使用一种新的热机械方法来增强析出硬化，从而提高某些铝合金的强度，超过了众所周知的T6热处理等标准工艺所能达到的效果。新工艺的应用正在作为与BCAST合作的大型EPSRC研究计划(STEP Al)的一部分进行研究，在该计划中，从合金设计和直流铸造到挤压和形变处理等高性能铝合金的开发的各个方面都在基础水平上进行研究。根据STEP方案，本项目将侧重于量化用于工程应用的经过处理的铝合金的机械性能。

Constellium Extrusions is leading the way for automotive light-weighting, through development of high-performance aluminium alloys with increased strength, toughness, and thermal conductivity. The company is currently using a novel thermomechanical approach to enhance precipitation hardening - and hence, the strength of certain aluminium alloys - beyond what can be achieved through standard processes such as the well-known T6 heat treatment. Application of the new process is being investigated as part of a large EPSRC research programme (STEP Aluminium) with BCAST, where various aspects of the development of high-performance aluminium alloys from alloy design and DC casting to extrusion and thermomechanical treatment - are being studied at a fundamental level. In alignment with the STEP programme, the present project will focus on the quantification of mechanical properties of the treated aluminium alloys for engineering applications.
