Abstract

This study investigates the time–temperature-dependent dissolutive behavior of copper using Ag-26.5Cu-1.5Ti (wt%) alloy powder. Prolonged thermal exposure under vacuum conditions causes significant Cu dissolution. Microstructural stratification reveals two distinct zones: Zone I dominated by Cu(s,s), Ag-Cu eutectic phase and Zone II containing Cu(s,s), Ag-Cu eutectic phase, Ti₂Cu and TiCu. Analysis demonstrates near-equilibrium dissolution attainment within 30 min at 880 °C. A four-stage dissolutive mechanism is proposed.

真空钎焊诱导AgCuTi/Cu体系溶解机理

本文研究了Ag-26.5Cu-1.5Ti （wt%）合金粉末对铜的随时间温度变化的溶解行为。在真空条件下长时间的热暴露会导致大量的铜溶解。显微组织分层显示出两个明显的区域：I区以Cu（s,s）、Ag-Cu共晶相为主，II区含Cu（s,s）、Ag-Cu共晶相、Ti2Cu和TiCu。分析表明，在880°C下，30分钟内达到接近平衡的溶解。提出了四阶段溶解机理。
