一项关于受锡铅焊料影响的冷变形铜的定量重结晶的研究
已经观察到，商业纯铜的分数重结晶特性受个人或SN-PB焊料的组成元素的存在影响。为了设计实验，研究了商业上的纯Cu，二进制铜合金（CU-SN和CU-PB）和三元铜合金，CU-SN-PB。铸造合金均质化，处理溶液，然后淬火以完成热处理。为了重结晶，合金将厚度冷至75％，然后在700°k的等温度等于3600秒的时间内将其退火。在本实验中，评估退火样品的分数重结晶为在各个时间步骤中记录的微硬度的归一化差异。为了验证实验结果，著名的Johnson-Mehl-Avrami-Kolmogorov方程也用于预测相关的重结晶行为。可以从研究中推断出，SN-PB焊料合金元素的存在对纯铜的重结晶行为具有积极影响，因为固体溶液加强了，其中锡的效果大于铅的作用。定量分析表明，纯Cu，Cu-Sn，Cu-Pb和Cu-Sn-PB合金的重结晶分别达到99.4％，95.4％，98.4％和89.5％。SN与Cu形成金属间，但PB却没有。此外，SN与杂质形成不同的金属间，并具有与Cu和Pb的FCC不同的BCC晶体结构。结果，退火过程中GP区域的形成和金属间相显示了两种方法之间的重结晶行为的差异。结合使用，冷滚动合金的微结构研究揭示了第二阶段的细长晶粒，并且在700°K的1800秒退火后，合金几乎完全重新结晶。

SAA3-1723-01
本附件（“附件”或“附件 01”）为伞状协议编号 SAA3-1723（以下简称“协议”或“伞状协议”），旨在供美国国家航空航天局格伦研究中心（“NASA GRC”或“NASA”）和 Relativity Space, Inc.（“Relativity”或“合作伙伴”）合作开发用于太空推进的氧化铝强化铜合金。NASA GRC 将生产氧化铝涂层铜 (Cu) 金属粉末原料。Relativity 将打印涂层原料。然后，Relativity 和 NASA 将对增材制造 (AM) 氧化物弥散强化 (ODS) Cu 样品进行机械和微观结构分析。最后，Relativity 将进行热导率测试，以确定新合金的性能是否优于 GRCop42 等传统 Cu 合金。
超越构建体积：冷喷涂增材制造......
冷喷涂增材制造 (CSAM) 使用惰性气体载体将金属粉末加速至超音速并将其喷射到目标物体上，随后粉末颗粒在目标物体上变形并通过固态结合粘附在基材上。通过更换粉末，该技术可用于制造多材料（或分级材料）部件。高性能液体火箭发动机 (LRE) 燃烧室通常是双金属的，结合了高热导率铜合金衬套和高强度镍合金结构夹套。因此，CSAM 工艺对于液体火箭发动机燃烧室制造具有许多优势。本文讨论了使用 CSAM 进行 LRE 制造的优缺点，然后描述了使用 CSAM 技术制造的演示双金属燃烧室的设计，并展示了制造试验的结果。
