TC3钛合金冷轧板的再结晶及冷轧与再结晶织构的研究

用光学显微镜和x射线衍射等方法研究了TC3钛合金冷轧板经不同压下量单向冷轧和不同温度退火后,α相的再结晶及冷轧与再结晶织构的特点。建立了该合金的再结晶图。确定了该合金冷轧临界变形量和再结晶的温度范围,并测定了再结晶后α相的晶粒度级别和冷轧与再结晶织构的类型等。     

一种镍基合金γ′相中镁的行为

本文根据实验数据,研究了一种特殊镍基合金γ′相内镁的行为。揭示了大小两种γ′相含镁量不同的本质及镁随温度变化进入γ′相的规律,并对镁提高合金持久寿命给予了初步解释。     

The Behaviour of Mg in γ-phase in a Ni-base Superalloy

1.IntroductionSince the biginning of 1960s,the effectof Mg upon superalloy has been studiedand some satisfactory developments havebeen achieved.The role of Mg on the alloycan be summarized as follows:(1)Themechanical plasticity of Ni-base superalloycan be improved by adding Mg asdesulphurizer,because of forming insolubleMgS instead of other low melting eutectic
