研究了铸造Fe-Pt磁性合金（Fe-36 at % Pt）激光焊接到三种金合金上的接头性能。使用的金合金为ADA II型和IV型金合金，以及Ag基（Ag-Au）金合金。为每种合金制备铸造板（0.5 × 3.0 × 10 mm）。在对铸造Fe-Pt板进行热处理后，将它们与三种合金中的每一种对接，然后在200 V下用Nd：YAG激光器进行激光焊接。还为每种合金制备了均匀焊接的试样。拉伸试验以1 mm/min的十字头速度进行。记录失效载荷（N）和伸长率（%）。拉伸试验后，使用SEM检查断裂表面。均匀焊接的合金组的失效载荷值按以下顺序排列：Ag-Au合金> IV型合金> II型合金> Fe-Pt合金。在测试的三种合金中，焊接到Fe-Pt合金上的IV型合金具有最高的失效载荷值。伸长率结果往往遵循类似的模式。本研究的结果表明，IV型金合金是一种适用于激光焊接铸造Fe-Pt磁性合金的金属框架的合金。© 2005 Wiley Periodicals，Inc.生物医学材料研究杂志B部分：应用生物材料，2006年
This study investigated the joint properties of a cast Fe‐Pt magnetic alloy (Fe‐36 at % Pt) laser welded to three gold alloys. The gold alloys used were ADA Type II and Type IV gold alloys, and an Ag‐based (Ag‐Au) gold alloy. Cast plates (0.5 × 3.0 × 10 mm) were prepared for each alloy. After the cast Fe‐Pt plates were heat treated, they were butted against each of the three alloys and then laser welded with Nd:YAG laser at 200 V. Homogeneously welded specimens were also prepared for each alloy. Tensile testing was conducted at a crosshead speed of 1 mm/min. Failure load (N) and elongation (%) were recorded. After tensile testing, the fractured surfaces were examined with the use of SEM. The failure‐load values of the group of alloys welded homogeneously were ranked in the order of: Ag‐Au alloy > Type IV alloy > Type II alloy > Fe‐Pt alloy. The Type IV alloy welded to Fe‐Pt alloy had the highest failure‐load value among the three alloys tested. The elongation results tended to follow a similar pattern. The results of this study indicated that Type IV gold alloy is a suitable alloy for metal frameworks to which cast Fe‐Pt magnetic alloy is laser welded. © 2005 Wiley Periodicals, Inc.
