The effects of Niobium addition on dynamic and static recrystallization have been studied in a microalloyed HSLA steel during and after hot compression with strain rates from 9.6×10~(-4) to 1.7×10~(-1) in the temperature range of 800℃ to 1100℃. The results were compared with plain carbon steel of similar base-composition.

The effects of Niobium addition on dynamic and static recrystallization have been studied in a microalloyed HSLA steel during and after hot compression with strain rates from 9.6×10~(-4) to 1.7×10~(-1) in the temperature range of 800℃ to 1100℃. The results were compared with plain carbon steel of similar base-composition. The peak strain in the true stress-true strain curve, known asthe characteristic strain for the initiation of dynamic recrystallization, was increased, by Niobium addition. The apparent activation energy for dynamic recrystallization was 74.9 and 30.4 kcal/mol, for Nb-bearing steel and plain carbon steel, respectively, The results indicate that the dynamic recrystallizationids considerably retarded by Niobium addition. The static recrystallization process has been examined in detail by a light microscope. Hot deformed austenite recrystallizes fall in two aspects: one being strain-induced migration of the already existing boundaries, and the other, which dominates, being the nucleation of the new recrystallized grains at grain boundaries or/and anncaling twin boundaries and the subsequent growth of the nuclei into the deformed matrix. Static recrystallization is also considerably retarded and nearly suppressed at 800℃. The kinetics of the strain-induced precipitation in deformed austenitc and static precipitation in undeformcd austenitc has also been studied through the measurement of secondary hardening. The results show that true strain up to 0.357 accelerates precipitating process by nearly two orders of magnitude. The distribution of particle size has been determined by the extraction replication technique. As recrystallization proceeds, a new population of larger particles forms. This can be explained by abnormal coarsening brought about by the passage of the recrystallization front. The micromechanism of the interaction between recrystallization and carbide precipitation is also discussed. The reason for the retardation of recrystallization is mainly due to the solute drag effect on grain or subgrain boundaries and the pinning effect of the precipitates at these boundaries. According to the recrystallization and precipitation behavior of Nb-bearing HSLA steel, some considcrations for a better choice of controlling rolling parameters have been proposed.

本文对10MnNb钢热形变奥氏体的再结晶和沉淀过程进行研究,并与16Mn钢作对比,以判别铌的影响。铌的微量添加使形变奥氏体的动态回复与再结晶过程得到延缓。无铌钢动态再结晶的表现激活能为30.4kcal/mole,而含铌钢则为74.9kcal/mole。铌的添加亦明显地阻碍热形变奥氏体的静态回复与再结晶;在800℃时,含铌钢的静态再结晶几乎完全被抑制。形变奥氏体的再结晶有两种方式:一种是应变诱导晶界迁移,但不是主要的方式,主要的是通过原奥氏体晶界或退火孪晶界上形核并长大。形变奥氏体中的应变诱导碳化物沉淀和未形变奥氏体中碳化铌的静态沉淀研究表明:0.357的应变量可使碳化物沉淀过程加速两个数量级。再结晶过程改变了沉淀粒子的尺寸与分布。这是由于再结晶前沿界面引起沉淀粒子快速粗化所致。本文对再结晶和沉淀过程的交互作用的微观机制进行了探讨。铌抑制再结晶过程的原因是由于溶质原子对晶界或亚晶界的拖曳效应以及碳化铌沉淀粒子对这些晶界的钉扎作用。根据铌对热形变奥氏体再结晶与沉淀过程的影响规律,对优选10MnNb钢的控制轧制工艺参数作了分析并提出了建议。

Based on experimental analysis of isothermal transformation diagrams (T T T curves) of various Mn-B steels, detailed discussions are made on the influence of elements Mn and B and the Mn-B interaction on the shape and position of T T T curves.
