Abstract

Ag-Sn-In-Ni-Te alloy ingots were produced through a heating-cooling combined mold continuous casting technique; they were then drawn into wires. However, during the drawing process, the alloy wires tended to harden, making further diameter reduction challenging. To overcome this, heat treatment was necessary to soften the previously drawn wires. The study investigated how variations in heat treatment temperature and holding time affected the microstructure, microhardness and corrosion resistance of the alloy wires. The results indicate that the alloy wires subjected to heat treatment at 700 °C for 2 h not only exhibited a uniform microstructure distribution, but also demonstrated low microhardness and excellent corrosion resistance.

摘要

通过加热-冷却组合模具连续铸造技术制备了Ag-Sn-In-Ni-Te合金铸锭；然后将它们拉制成线材。然而，在拉拔过程中，合金线材容易硬化，使得进一步减小直径具有挑战性。为了克服这一问题，需要进行热处理以使先前拉拔的线材软化。该研究调查了热处理温度和保温时间的变化如何影响合金线材的微观结构、显微硬度和耐腐蚀性。结果表明，在700℃下热处理2小时的合金线材不仅呈现出均匀的微观结构分布，而且显微硬度低，耐腐蚀性优异。
