摘要：
The invention concerns a process for shaping an alloy comprising mainly β or near-β phase Ti, comprising the steps of: - preparing a homogeneous particle powder mixture comprising micrometric particles of pure Ti and nanometric particles of at least one additional element or compound promoting the beta phase of Ti during the cooling of same from the α-β phase transition temperature of same - exposing said particle powder mixture to a focused energy source that selectively heats at least a part of a bed of said homogeneous powder mixture to a temperature of between 850 and 1850 °C - cooling the part that has been exposed in this way, preserving the β phase of Ti.
