Transient liquid phase sintering of Fe-Cu-Ti compacts

Differential thermal analysis (DTA) has been used to study transient liquid phase sintering in Fe-Cu-Ti. Three different liquid phases formed and disa ppeared by interdiffusion whilst the compacts were heated to 1350 degrees C . DTA of the sintering process can give important information on the sinter ing behaviour of the system, mainly the appearance and disappearance of the liquid phases, not obtainable by conventional metallographic and dilatomet ric examination. It has also been shown that this method is of practical in terest because it enables the sintering conditions to be optimised. (C) 199 9 Elsevier Science S.A. All rights reserved.
