本文对Bi—Sn合金在常温下产生超塑性的条件进行了研究。并分析认为Bi—Sn合金模具的失效与其超塑性能有关。提出了提高Bi—Sn合金模具寿命的基本途径。
In this paper, the conditions of superplasticity of Bi-Sn alloy at room temperature were studied. The failure of the Bi-Sn alloy mold is also considered to be related to its superplasticity. Proposed to improve the life of Bi-Sn alloy die basic approach.
