چکیده

Abstract. The difficult formability of Ti2AlNb alloy leads to the difficulty traditional manufacturing methods form complex thin-walled components, limiting wide application in aerospace. In this paper superplastic forming process Ti2AINb with structure was studied. tensile tests were carried out at varying temperature ranging from 920℃ 980℃ and strain rate 0.001s-1 0.03s-1. effect deformation-temperature on deformation behaviour analysed, showing that flow stress elongation increase increasing decreases, increases decrease rate. reaches maximum value 525% 940℃ 0.001s-1. constitutive equation taking into account developed, which implemented FE-based software Abaqus simulate structure. optimal values slab thickness loading pressure-time curve obtained by simulation performed. comparison between numerical experimental data regard variation verified accuracy finite element model. research results provide a reference basis for preparation structures

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Towards Superplastic Forming of Az31 Magnesium Alloy with Controlled Microstructure

A recent study on post-superplastic forming properties has shown that heating time prior to testing has a major effect on the post-forming properties of superplastically-formed AZ31 Magnesium alloy sheets. To this point, there has been very little examination into the effects of pre-heating or annealing on superplastic forming. In this work, these effects are examined using AZ31 Mg alloy sample...

Superplastic hemispherical Bulge Forming of a Ti-Al-Mn Alloy

Superplastic sheet thermoforming has been identified as a standard processing route for the production of complex shapes, especially in the aerospace industry. Ti-Al-Mn (OT4-1) alloy is currently being used for aero engine components as well as other aerospace applications by forming through a conventional route which is typically cost, labour and equipment intensive. The Ti-Al-Mn alloy (made a...
