| Abstract Scope |
The recent development of a hot stage has allowed Profilometry-based Indentation Plastometry, which can be used to obtain stress-strain curves more quickly and easily than via tensile testing, to be applied at temperatures up to 800°C. The low thermal inertia of this stage and small material volume requirements offer advantages in terms of minimising the time at temperature. An area of interest concerns application to refractory metals, increasingly used for ultra-high temperature applications. This paper covers application of HT-PIP to several refractory metals, including tungsten and niobium alloys, under a range of conditions. The sensitivity of the materials to oxygen uptake and oxidation has also been studied. It is shown that the technique can be used to obtain reliable stress-strain curves in a manner that offers significant advantages over conventional procedures. |
