摘要

在热轧和随后的热处理（即在 980°C、30 分钟的温度下奥氏体化并以不同的速度冷却）之后，对管材钢 06Mn2MoNb 进行了研究。通过使用各种取向关系的取向显微镜和结晶分析，证明了根据钢中变形奥氏体的转化产物（马氏体、贝氏体）来创建结构和纹理特征的可能性。研究表明，变形γ相晶粒之间的结晶有序边界上产生的α相可以解释多变量γ→α转变产生的结晶纹理。

Crystallographic Features of Phase Transformations in High-Strength Low-Carbon Pipe Steel

Pipe steel 06Mn2MoNb is studied after hot rolling and subsequent heat treatment, i.e., austenitizing at 980°C, 30 min and cooling at different rates. By means of orientation microscopy and crystallographic analysis using various orientation relationships the possibility is demonstrated of creating structural and textural characteristics based upon transformation products (martensite, bainite) of deformed austenite within the steel. It is shown that the crystallographic texture resulting from a multivariant γ → α-transformation may be explained by α-phase generation at crystallographically ordered boundaries between deformed γ-phase grains.
