pressed and sintered Ti6Al4V is of 98% density, while hot isostatically pressed Ti6Al4V has density of at least 99%. What fundamental mechanisms may be responsible for the higher density achievable by HIP? Consider the pressed + sintered route. Investigate: For this alloy, what pressure is used during pressing? What temperature and time at temperature are used during sintering? The density of the sintered (fired) compact is 98%. If the linear shrinkage during sintering is 2%, what should be the density of the pressed (green) compact?
