Ti3 AL-Nb-Mo composites were prepared by ShS using initial powder mixtures of Ti-Al-Nb-Mo and their corrosion and mechanical properties were studied to develop bioand environmental materials. The composites reached 99.8% of theoretical density after the direct consolidation. The composites shows equiaxed primary a2 in a matrix of fine secondary a2 plates and ordered 82 (Bo) forming a basket weave structure. The strain rate sensitivity (m = dlnσ/dlne) at 2% strain is 0.008. Corrosion potential and corrosion rate of the composites formed by ShS were -151. 5m VShE and 5. 72× 10^(-8)A/cm2 for Ti3 Al-10Nb-1. 5Mo and - 138.4m VShE and 4. 12×10^(-8)cm2 for Ti3 Al-12Nb-1.5Mo in a 50% NaOh-10%FeCI3 solution, respectively. Corrosion resistance decreased with niobium content in the composites and chloride content in the aqueous solution. Selective corrosion of a2 phase in a matrix occurred in the corrosion environment which suggests that the corrosion potential and rate changes are related to the niobium content and Q2 phase in a matrix.

探讨了在0.5Tm(Tm为材料熔点)温度附近一种氧化物粒子弥散强化的铁基合金中惰性气体离子辐照引起的组织结构变化.实验利用高能20Ne离子辐照材料样品至3个剂量水平.借助透射电子显微镜发现,即使在最高辐照剂量,材料的晶界处也没有发生空洞的加速生长,显著区别于相同辐照条件下传统铁基合金的组织结构变化.这个特点反映出氧化物粒子弥散强化合金具有在高温和高氦产生率的苛刻环境中(诸如在聚变堆内部)使用的潜力.晶界处空洞生长的抑制效应可归因于材料晶粒内部高密度的氧化物纳米颗粒的界面对惰性气体原子的有效俘获和对辐照缺陷的回复作用.

In 1872, George huntington presented his essay “On chorea” to the Meigs and Mason Academy of Medicine and, in doing so, detailed a disease that would later bear his name. huntington's disease(hd) is a genetic, neurodegenerative disease that manifests as the loss of motor control,cognitive impairment,and mood and psychiatric changes in paents.

To investigate the effect of aging treatment on irradiation-induced segregation of high Mn-Cr steel, specimens for electron-beam irradiation were prepared from the high Mn-Cr austenitic steel which was solution treated at 1 373 K for 1 h and aging treated at 573 K for 1 000 h, respectively. The electron-beam irradiation was performed at 573 K up to doses of 5.4 dpa in a 1 250 kV hVEM and irradiation-induced segregation analyses were carried out by an EdX in a 200 kV FE-TEM. The results show that void formation is not observed in both solution treated and aging treated ones. The amount of Cr segregation at the grain boundary decreases in the aged one; however, that of Mn is not changed in solution treated one.
