摘要

利用电子背散射衍射（EBSD）技术和基于Rodrigues-Frank（R-F）空间的取向差分析方法研究双相不锈钢中过饱和铁素体（α）经1323K沉淀析出的奥氏体（γ）相的晶粒取向和界面（晶界和相界）特征分布。结果表明：α晶粒经ε=2预先轧制变形后，γ析出相具有较强的织构，晶粒内取向差呈现以小角度晶界为主，孪晶界次之的晶界特征分布，这些晶粒与α基体的取向关系满足K-S，N-W和Bain关系的数量基本相当。具有相同取向而未经轧制变形的α晶粒沉淀析出的γ晶粒取向基本随机分布，与基体的取向关系主要以K-S为主；但内部发生孪晶的γ晶粒与基体不再满足K-S关系，其周围的相界约有1/4满足35°/〈110〉的新型取向关系。

Abstract：

The grain orientation and the interface character distribution were investigated for γ precipitation from the supersaturated α during aging at 1323K in duplex stainless steel by using EBSD technique and misorientation analysis based on Rodrigues-Frank (R-F) space. The results show that sharp texture and the grain boundary character distribution featured by a high population of low angle grain boundary (LAB) and a small number of twin boundaries (TBs) are produced in the γ precipitated from cold-rolled supersaturated coarse α with pre-strain of ε=2. The precipitated γ grains approximately possess K-S, N-W and Bain orientation relationship with the α matrix equally. For the unstrained α matrix of the same orientation, nearly random texture and the grain boundary character predominated by TBs are introduced in the γ precipitation after aging. Most of γ have K-S relation with the α matrix. However, twining in γ leads to the deviation from typical K-S orientation relationship. And also, one-fourth of phase boundaries along γ grains containing twins are found to obey a new orientation relationship of 35°/〈110〉 with α matrix.

Key words： grain orientation interface character distribution precipitation duplex stainless steel
