摘要
用强脉冲电子束辐照(“SOLO”装置，High-Current Electronics Institute SB RAS)过共晶Al- (22-24) Si组成的硅明样品。揭示了多相亚微米纳米晶结构的形成。结果表明，改性后的硅敏表面层硬度提高了2倍以上。在辐照初始状态和辐照后状态下，对扁平比例硅明样品进行了拉伸试验。辐照样品的延展性有所增加。
The Structure and Mechanical Characteristics of the Hypereutectic Silumin (Al–22–24 wt.% Si), Irradiated by a Pulsed Electron Beam
Irradiation (“SOLO” setup, High-Current Electronics Institute SB RAS) of hypereutectic Al- (22–24) Si composition silumin samples with an intense pulsed electron beam was carried out. The formation of a multiphase submicron nanocrystalline structure is revealed. It was found that after modification, the hardness of silumin surface layer increases by more than 2 times. Tensile tests were carried out for flat proportional silumin samples in the initial and after irradiation states. An increase in the ductility of irradiated samples was demonstrated.
