highly acidic environment beyond the optimum pH would impose an additional stress on microorganisms since the microbial cytoplasm must be maintained close to neutrality [5]. The processing pH 1.0......
<111>螺型位错滑移面的影响,结果发现Re的加入可以改变位错中心的对称性(如图1所示),降低位错滑移的阻力(佩尔斯应力 Peierls stress),增加滑移面的数目,有利于塑性变形的进行从而显著改善W的塑性和延展性[12, 14].此外,Re可以降低W合金的DBTT同时提高其RCT[15-16],拓宽W作为面向等离子体材料在反应堆中的可运行温度范围,提高其安全性. 在辐照性能方面...得W的表面发生熔融,起泡和开裂,可见Ti对W在强瞬态热负荷下的稳定性是不利的. 综上所述,Ti可以提高W基材料的密度和强度,但同样也会提高W的DBTT,高温下的脆性仍然很大,此外Ti也不利于W的抗热冲击性能. 图9 不同温度下W-1%TiC合金和W-2%Ti合金三点弯曲应力-应变曲线 Fig. 9 Stress-strain curves of three point......
