The use of materials with low specific weight is an effective way of reducing the weight of structures. Aluminum alloys are among the most commonly used lightweight metallic materials as they offer a number of different interesting mechanical and thermal properties. In addition, they are relatively easy to shape metals, especially in material removal processes, such as machining. Effect of Aging Treatment on Surface Roughness, Mechanical Apr 22, 2014 · The effect of aging treatment on the surface roughness and mechanical properties of AA6061 and AA7075 alloys was studied. Microhardness and tensile tests were used to investigae the mechanical properties. X-ray diffraction analysis was used to investigate the surface of the specimens. Furthermore, after tensile tests fractured surfaces were examined with scanning electron microscopy.

INTRODUCTION Aluminum alloy 6061 is one of the most widely used material. It is used in aerospace industries, construction Machinability Study of AA6061 Under Various Heat Mar 01, 2021 · Referring to extensive use of aluminum alloy (AA) 6061 in various types of industrial divisions, adequate knowledge of factors governing machinability aspects of AA 6061 under different heat treatment conditions (T6, T4, and T651) is important. This subject has received limited attention in the literature. Therefore, surface roughness, cutting force, tool wear as well as burr formation morphology, and chip shape were considered as the main machinability Machinability of a near beta titanium alloy - R A Rahman Oct 10, 2011 · Abstract. In this paper, the machinability of a near beta Ti25Nb3Mo3Zr2Sn titanium alloy with different heat treatment histories has been investigated in terms of cutting force, chip temperature and chip formation. A solution treatment was performed followed by ageing at different temperatures for the near beta alloy.
Similarly, it has been found that heat treatment of 6061, especially aging, influences the forces only at low cutting speeds, while at high speeds, the influence is negligible because of the low temper ature rise seen in the cutting zone [Demir H Mechanical properties and machinability of 6061 aluminum In this study, the effect of artificial aging on the machinability of 6061 Al-alloy was investigated for the as-received, solution heat treated (SHT) and solution heat treated and then aged (SHTA Pengaruh Natural Aging Sebelum Proses Artificial aging H.
