关键词： CrCoNi基（中）高熵合金；低层错能；变形机理；强化方法

摘要： 低层错能的CrCoNi基（中）高熵合金在室温或低温下具有优异的断裂韧性。同时，在冲击条件下变形机理的多样性使CrCoNi基（中）高熵合金具有优异的抗变形能力，有望作为抗冲击结构材料被应用于极端环境中。然而，金属材料“强度-塑性”的倒置关系在CrCoNi基（中）高熵合金中依然存在，低的屈服强度限制了C ...

摘要： 实现低剂量计算机断层成像(CT)的一个有效办法是减少投影角度,但投影角度较少会产生严重的条状伪影,降低图像的临床使用价值。针对该问题,提出一种耦合卷积神经网络(CNN)和多种注意力机制的U型网络(TE-unet)。首先采用U型架构提取多尺度特征信息;其次提出一个包含CNN和多种注意力的模块提取图像特 ...
