The notion of relative ω-compactness is introduced in L-order-preserving operator spaces,and some of its properties are obtained,such as that it is an L-good extension and hereditary with respect to subsets,and that it is preserved by continuously generalized Zadeh functions.
在L-保序算子空间中引入相对ω-紧性的概念,得到了它的一些性质,如它是L-好的推广,对子集遗传,被连续的广义Zadeh型函数所保持等。
Ω phase is the key hardening precipitate.
结果表明:实验用高纯Al-Cu-Mg-Ag合金板材具有较好的热稳定性和塑性,经185℃时效50h后合金的强度较峰值状态仅下降6%～7%,同时伸长率δ10保持在8%以上;Ω相是高纯Al-Cu-Mg-Ag合金的主要强化相,当合金处于峰值状态时,Ω相与基体之间会产生较大的错配应变,并在Ω相的细小片层处产生位错,为随后二次析出相θ′的析出提供有利的形核位置;延长时效时间将促进尺寸较大的Ω相和大部分θ′相(包括先析出相和二次析出相)向平衡相θ转变,但Ω→θ的转变远比θ′→θ的转变缓慢。
When the specimens were aged between 300 ℃ and 350℃, the globular ω phase formed firstly in β matrix, and then gradually transformed to equilibrium particle α ph.
结果发现:300℃~350℃时效过程中,在β基体上首先会形成球状ω相,α相必须借助中间过渡相ω形核,多呈颗粒状;400℃~450℃时效,α相既可通过中间ω相转变,多呈颗粒状,也可直接从β相中形核,多呈针状;500℃~650℃时效,针状α直接从β晶界或晶内析出,500℃以上时效可发现点状α相“连点成线”的现象,可能与变形带有关;700℃~750℃时效,平衡α相多呈棒状,700℃时效10min发现块状α相析出。
