复相材料的循环变形行为

对三种组织状态的F-M复相钢进行了对称和非对称循环加载条件下的形变研究.结果表明,双相钢的循环变形行为,不仅与组织中位错组态的演变过程有关,同时也受循环载荷大小、类型以及加载方式所影响.分析表明,双相钢的循环硬化、软化行为主要受控于两个基本过程,即循环变形时位错组态演变的物理过程和相间分载应力的转嫁、相间残余应力变化的力学过程.     

Application of annexation principle of thermodynamic property of In-Pb-Sb and In-Bi-Pb melts

Based on the principle of annexation and phase diagrams, the structural units of In-Pb-Sb and In-Bi-Pb melts were determined, and their calculating models of mass action concentrations were formulated. Calculated results agree well with practical values, which in turn show that the models deduced can reflect the structural realities of corresponding melts and the principle of annexation is applicable not only to some binary metallic melts, but also to ternary metallic melts.

宝浪油田侏罗系三工河组浅水辫状河三角洲沉积模式研究

焉耆盆地侏罗系三工河组广泛发育由辫状河进积到湖泊中形成的辫状河三角洲。这种三角洲特征显著不同于其它三角洲,其主体是辫状分流河道和水下分流河道。宝浪油田含油层段主体为辫状分流河道,以心滩发育为主要特征,是典型的浅水缓坡粗粒辫状河三角洲沉积。
