Caracterización de las transformaciones α↔β de la aleación Ti–6Al–4V y de las características mecánicas y microestructurales obtenidas

Abstract: En la aleación Ti-6Al-4V la fase α se va transformando en calentamiento en fase β hasta completarse al alcanzar la temperatura β-transus (≈1000 ºC). La identificación de la cinética de esa transformación es importante (y más todavía en otros tipos de aleaciones de Ti, como las super-α) para realizar tratamientos de solución en los que se deja sin transformar un determinado porcentaje de fase α (llamada primaria). En el presente trabajo se estudia y se valora la cinética y otras características de esa transform… Show more

“…Titanium (Ti) has two crystal phases in nature, HCP at room temperature (alpha phase) and BCC at 700-1050 C (beta phase). Alpha phase is fragile and betha is a ductile and meta-stable phase and a fine dispersion of both o them in the net allows a good combination of its biomechanical properties [7], [8], [9]. Ti alloys are classified in 3 types according to their microstructure:…”
