The angle between the lamellar boundaries in the cellular grains and the growth direction is either 45° or 90°.
结果表明,该合金在定向凝固过程中一次凝固可以以胞晶形式实现定向生长,胞晶内α2/γ片层方向与生长方向成45°或90°。
The fracture mechanism of fully lamellar Ti 49at% Al alloy has been investigated by studying the interactions between crack and lamellae or grain boundary.
通过对裂纹与晶内片层和晶界的交互作用的原位观察 ,研究了全层状组织 Ti Al基合金的断裂机制。
