Research on heat treatment of TiBw/Ti6Al4V composites tubes
Graphical abstract Display Omitted
Highlights An novel method was proposed to fabricate TiBw/Ti6Al4V composites tubes. Effects of heat treatment on mechanical properties of tubes were investigated. The failure mechanism of TiBw/Ti6Al4V composites tubes was revealed.
Abstract Heat treatment with different parameters were performed on the hot-hydrostatically extruded and swaged 3.5vol.% TiBw/Ti6Al4V composites tubes. The results indicate that the primary α phase volume fraction decreases and transformed β phase correspondingly increases with increasing solution temperatures. The α+β phases will grow into coarse α phases when the aging temperature is higher than 600°C. The hardness and ultimate tensile strength of the as-swaged TiBw/Ti6Al4V composite tubes increase with increasing quenching temperatures from 900 to 990°C, while they decrease with increasing aging temperatures from 550 to 650°C. A superior combination of ultimate tensile strength (1388MPa) and elongation (6.1%) has been obtained by quenching at 960°C and aging at 550°C for 6h. High temperature tensile tests at 400–600°C show that the dominant failure modes at high temperatures also differ from those at room temperature.
