The results show: the strongest bond is the Al-Al bond in the segregated cell without containing vacancy, where the Al atomic covalence radius is greater than that of Li atom in the cell; while the strongest bond is the Al-Li bond in the segregated cell containing vacancy, and the Al atomic covalence radius in the cell is less than that of Li atom. Since the difference of electronagativity between the Al and Li atoms is obvious, it is inclined to formed the Al-Li segregated cell of short range order structure in the condition of vacancy present. The short range order structure containing vacancy is probably the embryo or precursor structure of the metastable phase δ′(Al3Li). Because the strongest covalent bond in the Al-Li-vacancy segregated cell in alloy formed in quenching is the main strength reason for supersaturated solid solution of alloy. The bond net of succeeding precipitation of δ′(Al3Li) has the picture of anisotropic Al-Al bonding and the bond intensity enhanced. Since the δ′(Al3Li) is coherence with matrix, the bond net strength is enhanced by the precipitation of δ′(Al3Li) and so strengthen the alloy.
计算结果表明:不包含空位的偏聚晶胞的键络最强键为Al—Al键,其中Al原子的共价半径较Li原子的共价半径要大;而含空位的偏聚晶胞的最强键为Al—Li键, Al原子的共价半径要比Li原子的共价半径要小;在空位存在的情况下,由于Al原子与Li原子的电负性相差明显,促使Al和Li原子结合,倾向形成Al-Li短程序结构偏聚区,这种含空位的短程序结构很可能就是δ′(Al3Li)亚稳相的前兆结构和生长胚胎;由于Al-Li-空位有序偏聚晶胞的Al—Li键络比基体键络要强许多,因此,淬火过程中合金生成的Al-Li-空位偏聚晶胞对合金过饱和固溶体起主要强化作用;后续析出的δ′(Al3Li)亚稳相键络各项异性显著,键络强度明显提高;由于Al3Li与基体共格,其大量均匀弥散析出起到提升基体整体键络强度,同样对合金产生强化作用。

In fact, the total energies for the possible metastable alloy phases of A〓B and AB〓 types of six possible structures were calculated as a function of their lattice constant to find out if the respective metastable phases of A〓B or AB〓 types could be relatively stable in the selected systems. The calculation not only predicted the possible metastable states but also the lattice constant of the corresponding metastable alloy phases of either FCC or HCP structures.

When metastability occurs the clock-to-out time can be extended beyond the register's nominal tCO time. The additional time beyond the tCO time for the output signal to settle to a known state is known as the settling time. The tMET of a synchronization register chain is the sum of all output slacks of the registers in the chain.
对于这段话,我的理解是: tMET 时间和 tCO 时间之和就是异步时钟域的亚稳态时间,如果这个时间大于目的时钟域的同步寄存器链的时序余量(大概是时钟周期减去它的建立时间和保持时间之和吧),那么这时候系统采到的信号一定是亚稳态。
