TA2工业纯钛连续冷却过程中β→α相变的原位观察
In-Situ Observation of β→α Phase Transformation of TA2 Commercial Pure Titanium during Continuous Cooling
摘 要
用共焦激光扫描显微镜原位观察了TA2工业纯钛在20 ℃·min-1冷速下的β→α相变过程。结果表明: β→α相变分为晶界α相的形核长大和魏氏体α相的形核长大两个阶段; 晶界α相由在β相晶界处的多个α晶核长大连接而成, 且至少与相邻β晶粒中的一个保持取向关系; 魏氏体α相在晶界α相上形核并长大, 以层片状集束形式向β相内生长, 其伸长速度远大于增厚速度。

Abstract
The β→α phase transformation process of TA2 commercial pure titanium at the cooling rate of 20 ℃·min-1 was in-situ observed using a confocal laser scanning microscopy (CLSM). The results show that β→α phase transformation process could be divided into two stage, including the nucleation and growth of grain boundary α phase and widmanstatten α phase. Grain boundary α phase was formed by the growth and connection of several α nucleuses along β phase grain boundaries, and kept orientation relationship to at least one of the adjacent β grains. Widmanstatten α phase nucleated on α phase grain boundaries, and grew forward to β phase in the form of lamellar-type clustering. The lengthening speed was much higher than the widening speed.
