| 摘要 |
The present invention relates to a plug element having at least one among body units (21, 31, 32, 33) having a shape-memory-alloy material (14), wherein body units (21, 31, 32, 33) are connected to at least one carrier element (2, 3) by coming in contact with the carrier element in at least a radial direction in specific regions. The body unit can be cooled and can be mechanically formed to have a first shape, and the first shape can be deformed to have a second shape by subsequent heating, and the body units (21, 31, 32, 33) come in contact with the carrier elements (2, 3) in the radial direction when the first shape is deformed to have the second shape. |
