Solid-state foaming of Ti–6Al–4V by creep or superplastic expansion of argon-filled pores
Ti–6Al–4V foams are produced by the expansion of pressurized argon pores trapped in billets created by powder metallurgy. Pore expansion during thermal cycling (840–1030 C, which induces transformation superplasticity in Ti–6Al–4V) improves both the foaming rate (by reducing the flow stress) and the final porosity (by delaying fracture of the pores and subsequent escape of the gas), as compared...
متن کاملVickers hardness of cast commercially pure titanium and Ti-6Al-4V alloy submitted to heat treatments.
The purpose of this study was to evaluate the effect of heat treatments on the Vickers hardness of commercially pure titanium and Ti-6Al-4V cast alloys. Six-millimeter-diameter cylindrical specimens were cast in a Rematitan System. Commercially pure titanium and Ti-6Al-4V alloy specimens were randomly assigned to 3 groups (n=10) that received the following heat treatments: control (no heat trea...
متن کاملSuperplastic 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...
متن کاملEffect of Stone Cast Type on Complete Denture Base Adaptation
Introduction: Few researches have been conducted researches on the influence of the type of dental stone used for fabrication of casts on the adaptation of denture bases. The purpose of this study was to compare the effect of two types of stone casts on the accuracy of fit in complete denture bases. Methods: Using sixty fully replicated master casts obtained by duplicating a metal die represent...
متن کاملCutting Properties Analysis of Titanium Alloy (Ti-6Al-4V) Base on Cryogenic Cooling
This paper studied the cutting properties of Ti-6Al-4V under cryogenic cooling to find a solution of improvement in tool load-carrying, thermal stress, tool life and finish quality. Firstly, this paper established a 3-D cutting model of Ti-6Al-4V under cryogenic cooling with liquid nitrogen, and then set the parameters of material, friction model and cutting conditions. Based on this model, the...
