Precipitation induced recrystallization -Clarification of new recrystallization phenomena and its application to texture control

研究了初始α晶界和板条马氏体组织对析出再结晶（PIR）的影响。在取向偏差大于5度的边界处，再结晶晶粒的生长受到抑制，形成新的铁素体晶粒。在奥氏体高铬合金中发现了PIR，其中添加Ni使奥氏体稳定。这意味着当析出相的体积分数较高时，无论基体的晶体结构如何，PIR都可以发生。

The effects of initial α grain boundary and lath martensite structure on precipitation induced recrystallization(PIR) have been investigated. The growth of recrystallized grains is inhibited at the boundary misoriented larger than 5 degrees, resulting in the formation of new ferrite grain at these boundaries. The PIR was found to appear in the austenitic high-Cr alloy in which austenite is stabilized by the Ni addition. This implies that the PIR can takes place generally regardless of crystal structure of the matrix when the volume fraction of precipitate is higher.
