Infrared Brazing of Ti-6Al-4V and 17-4PH Stainless Steel coated by Cr/Ni thin film.

open access: yes, 2007
本研究分別使用銀基填料BAg-8、Ag-Cu-1.75Ti,和鈦基填料Ti-20Zr-20Cu-20Ni,對Ti-6Al-4V合金及具有不同表面鍍層之17-4PH不鏽鋼進行紅外線硬銲接合,期望藉由鍍層做為擴散阻隔層,阻擋填料與基材間的交互擴散以避免硬脆之介金屬相形成,得到最佳的剪力強度。實驗結果顯示,使用BAg-8填料與表面鍍鉻及鍍鎳之17-4PH不鏽鋼之接點可得到最佳的剪力強度;而使用Ag-Cu-1.75Ti填料與表面鍍鉻者剪力強度較前者低,但仍不錯。比較其顯微組織,發現均破斷於具脆性之Ti ...

Six-channel laser single-channel coaxial wire feeding: anisotropy study of component gradient material for 316L and 17-4 PH stainless steel

open access: yesJournal of Materials Research and Technology
A martensitic 17-4 PH stainless steel wire was processed via additive manufacturing using a six-channel laser system. The wire was then replaced mid-process with an austenitic 316 L stainless steel wire to continue printing, ultimately resulting in the ...
