SOME FACTORS AFFECTING THE METALLURGICAL MICROSTRUCTURE AND CREEP PROPERTIES OF THE TITANIUM 3 AL 6 SN 5 ZR 0.5 SI TYPE OF ALLOY,

Abstract

Optical and electron metallographic techniques have been used to study the microstructure of Titanium 3Al 6Sn 5Zr 0.5 Si type alloy (Hylite 55) and Titanium 3Al 6Sn 5Zr 2 Mo 0.5 Si type alloy (Hylite 60) containing 0.005 wt %, 0.42 wt % and 0.75 wt % Si after beta annealing treatments at 1000 deg.C, followed by either air cooling or water quenching from room temperature and then ageing for 24 hrs at 500 deg.C. The creep properties of these alloys have been determined by testing at 500 deg.C. and 18 tsi for approximately 1000 hours.
