中文摘要 | 本研究之目的乃在探討與嘗試解決壓鑄鋁合金於T6處理時會產生起泡現象(Blistering)之問題。本研究主要以ADC3(Al-9.2 Si-0.4 Mg-0.3 Fe,及額外添加2%、4% Cu)壓鑄鋁合金材料及其壓鑄件作為研究對象,分析壓鑄鋁合金材料內析出物之固溶與析出行為,探討適當之不起泡固溶溫度及時間條件,並利用合金設計及調整熱處理條件之方式,使壓鑄鋁合金可藉由適當之T6處理(包括不起泡固溶處理、淬水及人工時效)達到析出強化效果。 |
英文摘要 | This study deals with the blistering problem in die casting Al alloys when they are subjected to T6 heat treatment. In order to realize the onset temperature and time conditions for the blistering problem to occur, the common die casting alloys, namely ADC3 (Al-9.2 Si-0.4 Mg-0.3 Fe and with additions of 2% and 4% Cu), were used and subjected to a series of solid solutioning tests. Once the blistering onset conditions were identified, proper T6 heat treatment can be applied to the alloys without the occurrence of blistering. Through a careful selection of heat treatment conditions (not to exceed the blistering onset conditions) and proper adjustments of alloy compositions (to lower the required solid solution temperature) die casting alloys can be strengthened by the blistering-free T6 heat treatment. |
