Abstract:

In this study, the sourceability of Al6061-based B4C particle-added composite materials, produced by the powder metallurgy method, was studied by the TIG welding technique. B4C (<10 μm) powder with pre-alloyed Al6061 (<100 μm) powder in weight of 10% was mixed in a three-dimensional mixer for 45 minutes. The mixed powder was first pressed cold under 300 MPa pressure. The pressed block samples were subjected to a 60 minute Sintering process at 550 oC. Sinterlened block samples were again extracted by 1/4 in the special-designed extraction pattern at the same temperature. The extracted composite materials were produced composite sheets with a thickness of 4 mm, with a temperature of 550 oC. The T6 aging thermal process is applied to the produced composite leaves. For the purpose of studying the curability of produced composite leaves with the TIG welding technique, four different amper range (100-130-160-190 A) sources were made. The micro-building, hardness, break-up energy and drawing stretching values of the post-resource resource area have been analyzed. There is a source area in high flow intensity. At the 130 and 160 A current strength, the drawing resistance and the blow resistance are high, while at the low and high current strength, these values are low.
