Conventional Titanium Alloy

Conventional titanium alloy may be ignited and burnt under high temperature, high pressure and high gas flow velocity condition. In order to avoid this problem, a new kind of burn-resistant titanium alloy-double glow plasma surface alloying burn-resistant titanium alloy has been developed. Alloying element Mo is induced into the Ti-6Al-4V substrate according to double glow discharge phenomenon, Ti-Mo binary burn-resistant alloy layer is formed on the surface of Ti-6Al-4V alloy. The depth of the surface burn-resistant alloy layer can reach about 100 microns and alloying element concentration can reach 59%. High energy laser ignition experiments reveal that the ignition temperature of alloyed layer with Mo concentration about 10% is about 200°C higher than ignition temperature of Ti-6Al-4V.

A new numerical model is developed to simulate the 3-D inverse heat transfer in a composite target with pyrolysis and outgassing effects. The gas flow channel size and gas addition velocity are determined by the rate equation of decomposition chemical reaction. The thermophysical properties of the composite considered are temperature-dependent. A nonlinear conjugate gradient method (CGM) is applied to solve the inverse heat conduction problem for high-energy laser-irradiated composite targets. It is shown that the front-surface temperature can be recovered with satisfactory accuracy based on the temperature/heat flux measurements on the back surface and the temperature measurement at an interior plane.
