Twinning-related enhancement in strength and ductility of Cu-37Zn alloy by the cryogenic ultrasonic impact treatment supplemented with ECAP
نویسندگان
چکیده
The effects of ultrasonic impact treatment (UIT) and UIT with equal channel angular pressing (ECAP), on the microstructure Cu37Zn alloy are studied at ambient cryogenic temperatures. With decreasing process temperature, highly twinned areas submicro/nano-scale thickness/spacing, together dislocation tangles/cells, introduced in alloy. Direct microscopy observation stored energy release analysis confirm enhanced twinnings cryo-UIT cryo-UIT/ECAP treated that simultaneously provide superior Vickers hardness formability (twinning-induced plasticity effect).

Strength and ductility with {101̄1} — {101̄2} double twinning in a magnesium alloy
Based on their high specific strength and stiffness, magnesium alloys are attractive for lightweight applications in aerospace and transportation, where weight saving is crucial for the reduction of carbon dioxide emissions. Unfortunately, the ductility of magnesium alloys is usually limited. It is thought that one reason for the lack of ductility is that the development of - double twins (DTW)...

An AM30 magnesium alloy was processed through ECAP method at 200 °C. Optical and transmission electron microscopy as well as electron back scattered diffraction (EBSD) technique were employed to characterize the deformed microstructure. A partially recrystallized microstructure including ultrafine/nano structures was obtained. The area fraction of 49% was measured for the recrystallized regions...
متن کاملEnhancing Fatigue Strength by Ultrasonic Impact Treatment
Enhancement in fatigue performance of welded joints by Ultrasonic Impact Treatment (UIT) was evaluated in large-scale specimens having a nominal yield strength of 345 to 690 MPa. Eighteen rolled-beam specimens having welded details at cover plates and transverse stiffeners and eight built-up specimens having only transverse stiffener details were fatigue tested after treating them by UIT. A par...
متن کاملEnhancing the low cycle fatigue strength of AA6061 aluminum alloy by using the optimized combination of ECAP and precipitation hardening
In the present study, mechanical properties and low cycle fatigue behavior of a solid-solutionized AA6061 aluminum alloy produced by equal channel angular pressing (ECAP) process were investigated. The grain refinement after two passes of ECAP significantly increased the yield stress and ultimate tensile stress and decreased the ductility of the alloy. However, the improvement of low cycle fati...
