Hot stamping of an Al-Li alloy: a feasibility study

The feasibility of forming a third generation aluminium-lithium alloy (AA2060) into a complex shaped panel component, was studied by using an advanced forming technology called solution heat treatment, cold die forming and in-die quenching (HFQa) process. The main challenges using HFQ technology to form complex shaped AA2060 component was to find out optimum forming parameters, such as forming temperature, forming speed, lubrication condition and blank holding force. In this paper, the optimum forming temperature was mainly concerned. The flow stresses of AA2060 were obtained at different temperatures ranging from 350 to 520 °C at the strain rate of 2 s−1. The suitable temperature to achieve the adequate ductility was found at 470 °C. By forming the AA2060 blanks at the optimum forming temperature, experimental results exhibited the feasibility for forming complex-shaped AA2060 components. The formed components were analysed through strain measurements. The post-form mechanical properties of AA2060 were assessed using hardness and tensile tests

A Scholarly Review of Supply Chain Integration within the New Zealand Blueberry Industry

Ethics and credence attributes are the humanistic basis for establishing sustainable supply chain development. It determines brand reputation, ecology and customer experience. Furthermore, good ethics and credence Attributes promote the progress of industry leadership and increase the possibility of win-win strategies, especially in terms of negotiation. Negotiation is the premise of supply chain collaboration. The purpose of collaboration is to establish a synchronized supply chain to improve the ability of industry coordination. This is also the key to creating value, and the importance of risk management cannot be ignored. It is not only a guarantee for the smooth operation of the supply chain, but also an important measure to improve the flexibility of the supply chain. Finally, the results of supply chain integration need to rely on performance metrics and benchmarking to control and improve the overall performance of the supply chain. This publication evaluates modern theories in all these areas and contextualise it to the New Zealand blueberry industry. It is important that the reader appreciates the scholarly origin of this publication

Hot stamping of an Al-Li alloy: A feasibility study

The feasibility of forming a third generation aluminium-lithium alloy (AA2060) into a complex shaped panel component, was studied by using an advanced forming technology called solution heat treatment, cold die forming and in-die quenching (HFQ*) process. The flow stresses of AA2060 were obtained at different temperatures ranging from 350 to 520 oC at the strain rate of 1 s−1. The suitable temperature to achieve the adequate ductility was found at 470 oC. By forming the AA2060 blanks at the optimum forming temperature, experimental results exhibited the feasibility for forming complex-shaped AA2060 components. The formed components were analysed through strain measurements. The post-form mechanical properties of AA2060 were assessed using hardness and tensile tests. * HFQ® is a registered trademark of Impression Technologies Ltd
