中文摘要 | 綜合在西佛吉尼亞州大學的研究成果以深入探討用於太空板材之高強度鋁合金凝 固破裂之基礎機構。本研究採用三種實驗技術,第一是熱電耦放下裝置測試 DC 鑄件,第二 是鑄錠之熱機性質特徵與鑄造結構之相互關聯,第三是鑄錠熱與應力演變之數據模式。本研 究採用 7050 鋁合金,針對 DC 鑄件之瞬間與穩定階段探討。 |
英文摘要 | This paper summarizes research efforts at WVU, conducted to comprehensively understand the fundamental mechanism of solidification cracking of high-strength aluminum alloys for aerospace plate applications. Three important technical approaches were adapted: 1. in-situ thermal couples drop measurement of DC casting; 2. characterization of thermo-mechanical properties of cast ingots, correlated with the cast structure; 3. numerical modeling of ingot thermal/stress history. The alloy of interest was 7050. The research efforts focused on both the transient and steady stages of DC casting. |
