Abstract
This study presents the analysis of the microstructure and Vickers micro-hardness of β-Ti type Ti-15.05Mo alloy obtained by different cooling rates. The alloy was fabricated using an arc-melting furnace, solution treated in a muffle furnace and cooled using different cooling medium such as ice water, furnace cool and air cooling. The X-ray analysis of the as-cast showed β phases peaks only and water quenched samples showed peaks belonging to α″ and β phases. The (β, α) dual phases were detected in the furnace and air-cooled samples, respectively. The Optical Microscope (OM) micrographs of the as-cast Ti-15.05Mo sample showed large equiaxed β grains and sub-structures belonging to orthorhombic martensitic α″ phase. The water quenched sample showed β equiaxed grains, however their grains were much smaller You should leave 8 mm of space above the abstract and 10 mm after the abstract. The heading Abstract should be typed in bold 9-point Arial. The body of the abstract should be typed in normal 9-point Times in a single paragraph, immediately following the heading. The text should be set to 1 line spacing. The abstract should be centred across the page, indented 17 mm from the left and right page margins and justified. It should not normally exceed 200 words.
