Aluminum and gallium affect the performance of titanium plate

Aluminum and titanium, gallium can increase a + β / β transformation point . 10% aluminum phase transition point can be increased to about 1080 ℃. Gallium ability weaker . Aluminum titanium start improving recrystallization temperature of titanium alloys martensitic transformation start point (MS) is not affected. Excess aluminum and gallium in Ti3M generated based on the ordered phase a2 use temperature . Further titanium wire, the aluminum present in the metastable β phase , phase to promote ω a phase transition , thereby reducing the volume percentage of the time ω alloy phase.

Impact on the performance of aluminum and gallium , aluminum, titanium and gallium can improve the tensile strength at room temperature and high temperature has little effect on the high temperature plasticity. With increasing aluminum content of titanium - aluminum density and Poisson coefficient decreased linearly . Within the range of solubility , aluminum can effectively improve the elastic modulus of titanium , shear modulus, specific resistance and line expansion coefficient . When a2 phase, the emergence of a peak performance .

Titanium - appears to Ti3AL base of a2 ordered phase when the aluminum alloy , titanium alloy increases the tensile strength , ductility and toughness to deteriorate tittanium bar. This ordered phase is often a similar role with Ti3AL resistant titanium alloys for high temperature Ti3Ga phase in phase .
