The effect of the second-phase particle precipitation on the recrystallization texture of high-strength and fine-grain interstitial-free steel was studied. It is shown experimentally that the sizes of second-phase particles increase and their number decreases with holding time and annealing temperature. The texture is mainly influenced by the size, number, and distribution of the particles. Finely dispersed second-phase particles are strongly pinned on the grain boundaries, which significantly hinders the development of {111} surface textures. It the pinning force on the grain boundary decreases, the {111) surface texture improves due to the aggregation and growth of second-phase particles with holding time. The strength of the γ-phase ({111}<112> texture) grows and reaches maximum (annealing temperature 850°C), finally declines with annealing temperature. Precipitated particles of 40–60 nm favor the development of the {111} texture component.

二次相沉淀对高强度细晶粒无间隙钢再结晶织构的影响

研究了第二相颗粒析出对高强度细晶粒无间隙钢再结晶织构的影响。实验表明，第二相颗粒的尺寸随着保持时间和退火温度的增加而增加，其数量减少。质地主要受颗粒的大小，数量和分布的影响。细分散的第二相颗粒牢固地固定在晶界上，这严重阻碍了{111}表面织构的发展。如果第二相颗粒随着保持时间的聚集和生长，在晶界上的钉扎力降低，{111）表面织构得到改善。γ相（{111} <112>织构）的强度增长并达到最大值（退火温度850°C），最终随着退火温度下降。40-60 nm的沉淀颗粒有利于{111}织构成分的发展。
