Evolutions of texture and lattice strain of swaged brass samples were investigated by neutron diffraction at STRESS-SPEC under tensile deformation using a unique tension/compression rig. The two phased sample BS1 (61% α-brass and 39% β-brass) became 100% α-brass after 400 °C annealing (sample BS2). The starting texture of the as-received material BS1 was the typical <111>, <200> double fiber. This texture develops firstly by in-situ tension to a moderate strengthening. After annealing (BS2) the <111> fiber survives with surprisingly high strength and develops by in-situ tension a very strong <111> fiber of 39 mrd. Line broadening and lattice strain behaviour shows the development of the elastic strain and plastic strain.

锻造黄铜的拉伸载荷过程中的晶体织构和晶格应变演变

使用独特的拉伸/压缩装置,在拉伸变形下,在STRESS-SPEC上通过中子衍射研究了型锻黄铜样品的织构和晶格应变的演变。两相样品BS1(61%α-黄铜和39%β-黄铜)在400°C退火后变成100%α-黄铜(样品BS2)。接收到的材料BS1的起始织构是典型的<111>,<200>双纤维。这种质地首先通过原位张力发展到中等强度。退火(BS2)后,<111>纤维以惊人的高强度存活,并通过原位拉伸形成39 mrd的非常坚固的<111>纤维。线展宽和晶格应变行为显示了弹性应变和塑性应变的发展。
