摘要：

The AZ31 alloy is one of the most popular magnesium alloys with aluminum. Due to its low mass density and good mechanical properties, this structural material offers considerable potential for the aircraft manufacturing industry. The AZ31 alloy is used in the aircraft industry to produce flat parts with ribs, such as brackets. The paper presents the results of a quantitative study on the microstructure and mechanical properties of AZ31 alloy aircraft brackets produced by a new technology of semi-open die forging. The experimental tests of forming these flat ribbed parts were conducted at a temperature of 410 degrees C using a prototype forging press equipped with three moving tools. The microstructure and mechanical properties of the AZ31 alloy were examined at delivery and after hot forging. (C) 2015 The Authors. Published by Elsevier B.V.
