Riset ini bermaksud untuk mengetahui pengaruh variasi kedalaman pemotongan serta kecepatan atas nilai kekasaran permukaan aluminium 7075. kesimpulan berpengaruh spesimen. Bertambahnya yang dipakai meangkibatkan kualitas makin rendah (halus). Kedalaman tinggi menyebabkan menurunnya gaya pemotongan, setiap terdapat selisih Makin besar mengakibatkan meningkatnya permukaan, ketika kombinasi dari te...

This work proposes a methodology to compute fretting fatigue crack initiation and total life by iterative models calibrated with stress–strain-life curves. One of the main novelty such is assumption that length determined size critical distance. To separate propagation lives, numerical approach finite elements used. The incorporates not only multiaxial non-proportional characteristic stress fie...

Extrusion at 450?C of hot compacted premixed aluminium alloy powder 7075 resulted in full density and banded microstructure with the average transverse grain size 13.6 ?m after T6 heat treatment. It increased mechanical properties to yield tensile stresses 457 492 MPa, respectively elongation 6.4 %. These meet requirements ASTM standard ASM for 7075T6 conventionally manufactured similar chemica...

The influence of the ageing temperature on hardness, electrical conductivity, thermal diffusivity and conductivity EN AW-7075 aluminium alloy was studied in this paper. After solution treating at 480 °C for 1 h quenching it ice water, investigated characterized using Differential Thermal Analysis (DTA) order to determine optimal temperatures isochronal treatments. Afterwards, conducted range 11...

In this study, age hardenable material Aluminum alloy Al-7075-T6 (aged) was investigated for weldability. Al-7075-T6 plates were subjected to Al-7075-0 heat treatment and were joined with different welding parameters by means of friction stir welding method. After Joining, the parts which were subjected to tensile and bending tests were examined. As a result of the studies, it was observed that...
