摘要

展出了六种全新的双针FSW工具，每种工具都具有双圆、双三角形、双矩形和三角矩形轮廓的独特组合。开发了圆形、三角形和矩形的组合别针。对焊接接头试样进行准静态试验，收集应力应变信息。双针焊接设备的使用扩大了SZ，改善了塑性流动，以及其他微结构变化。使用双三角形和矩形三角形工具的焊接连接具有最高的抗拉强度和延展性。研究了刀具形状对Al 6061摩擦搅拌焊接接头搅拌区和热影响区拉伸特性和显微组织成分的影响。

A Productive Friction Stir-Welded Aa 6061 Joints Using Different Pin Tool Profiles Configuration to Grow Mechanical and Microstructural Characteristics

There are six brand-new dual-pin FSW tools that are displayed, each with a unique combination of Dual Circle, Dual Triangle, Dual rectangle, and Triangle-Rectangle profiles. Combination pins in the shapes of circles, triangles and rectangles were developed. The samples with the welded joints underwent quasi-static testing, and information on stress-strain was gathered. The use of dual pin welding equipment resulted in expanded SZ and improved plastic flow, among other micro-structural changes. The highest tensile strength and ductility were found in the weld connections made using Dual Triangle and Rectangle-Triangle tools. This investigation looks at the effects of tool shapes on the tensile characteristics and micro-structural components in the stir zone and heat-affected zone of friction stir-welded Al 6061 joints.

期刊介绍： Periodico di Mineralogia is an international peer-reviewed Open Access journal publishing Research Articles, Letters and Reviews in Mineralogy, Crystallography, Geochemistry, Ore Deposits, Petrology, Volcanology and applied topics on Environment, Archaeometry and Cultural Heritage. The journal aims at encouraging scientists to publish their experimental and theoretical results in as much detail as possible. Accordingly, there is no restriction on article length. Additional data may be hosted on the web sites as Supplementary Information. The journal does not have article submission and processing charges. Colour is free of charges both on line and printed and no Open Access fees are requested. Short publication time is assured. Periodico di Mineralogia is property of Sapienza Università di Roma and is published, both online and printed, three times a year.
