[ 1 ] - بررسی اثر میان لایه تیتانیومی بر خواص مکانیکی و ساختاری اتصال نفوذی فولاد- تنگستن

در این بررسی اتصال نفوذی فولاد- تنگستن با استفاده از لایه میانی تیتانیومی خالص انجام شد. نمونهها در فیکسچر مناسب تحت فشار MPa 5 درون کوره با اتمسفر آرگون در دماها و زمانهای مختلف قرار گرفتند. تصاویر میکروسکوپ نوری و میکروسکوپ الکترونی روبشی (SEM) نمونهها نشاندهنده تشکیل ناحیه نفوذی قابل تشخیص در فصل مشترک تنگستن- تیتانیوم و نفوذ بسیار کم تیتانیوم در فولاد است. همچنین با افزایش زمان و دمای ...

[ 2 ] - Evolution of microstructures and mechanical properties of AZ31 magnesium alloy weldment with TIG and Pulsed TIG process

Magnesium alloys are very attractive materials owing to their properties of low density, high specific strength and stiffness, good castability, and weldability. AZ31 magnesium alloys in terms of weldability has better situation than the other, so it has more applications than other magnesium alloys. In this study, TIG and pulsed TIG welding method was used to welding the AZ31 alloy and finally...

[ 4 ] - Effect of friction stir welding parameters on the microstructure and mechanical properties of dissimilar AA2024-AA6061 joints

In the present study, to resolve the problems in fusion welding methods as well as to increase the strength, FSW method was used to join aluminum alloy sheets 6061 and 2024. Moreover, optimal parameters for joining of these two alloys were also taken into consideration. Various tool rotation speeds of 565, 950 and 1500 rpm were selected. For each tool rotation speed, two traverse speed variable...
