摘要
以国产1561 铝合金40 mm厚板材为研究对象,通过厚板拉伸、圆棒拉伸、布氏硬度、SEM等研究了不同批次40 mm厚1561 板材的力学性能及微观组织.结果表明:当板材心部附近出现明显的析出带时,材料的塑性和强度明显下降,拉伸断口出现裂纹分层.
Abstract
Taking domestic 1561 aluminum alloy 40 mm thick plates as research object,the mechanical properties and microstructure of different batches of 40 mm thick 1561 plates were investigated by plate tension specimen,round bar tension specimen,cloth hardness test and scanning electron microscope.The results show that when there is an obvious precipitation zone near the core of the plate,the plasticity and strength of the material decrease obviously,and the crack delamination appears on the tensile fracture.
