Bu çalışmada; endüstriyel sektörde tercih edilmesi yaygın olan AL1050 (%99,53 ticari saflıkta) malzemenin, çekme hızı (zımba hızı), numune eni ve zımba çapı değişiminin Erichsen Sabitine etkileri deneysel olarak incelenmiştir. Deneysel çalışmalarda tasarımı, imalatı kalibrasyonu yapılan tam otomasyonlu şişirme donanımından faydalanılmıştır. Deneyler 5 mm/dakika, 6,25 mm/dakika 8 hızlarında, TS ...

Nanostructural Al 1050 sheets were produced using a novel method of asymmetric cryorolling under ratios of upper and down rolling velocities (RUDV) of 1.1, 1.2, 1.3, and 1.4. Sheets were rolled to about 0.17 mm from 1.5 mm. Both the strength and ductility of Al 1050 sheets increase with RUDVs. Tensile strength of Al sheets with the RUDV 1.4 is larger 22.3% of that for RUDV 1.1, which is 196 MPa...

The influence of alloying additions on strengthening of high pressure torsion (HPT) processed alloys was investigated using commercially pure Al (Al-1050 alloy) and five Al-(1-3)Mg-(0-4)Cu alloys (in wt%). Microhardness was measured on cross sections. For Al-1050 the microhardness reaches a peak at an effective strain of about 3 and subsequently decreases. The microhardness of Al-Mg-Cu alloys i...

Abstract The current study reports three different techniques to estimate the distribution of dislocation density at mid thickness 1050 Al alloy. It is well known that strain inhomogeneous through rolled materials, which affects evolution during process deformation. In this study, number dislocations was calculated experimentally using indentation technique in 46.8% cold sheet and result verifi...

The ultrafine grained (UFGed) 1050 Al plates with a thickness of 2 mm, which were produced by the accumulative roll bonding technique after five cycles, were friction stir butt welded to 2 mm thick 6061-T6 Al alloy plates at a different revolutionary pitch that varied from 0.5 to 1.25 mm/rev. In the stir zone, the initial nano-sized lamellar structure of the UFGed 1050 Al alloy plate transforme...
