| 1 | Effect of Replacing Vanadium by Niobium and Iron on the Tribological Behavior of HIPed Titanium Alloys显示文摘This study aims to examine the effect of replacing vanadium by niobium and iron on the tribological behavior of hot-isostatic-pressed titanium alloy(Ti–6Al–4V)biomaterial,using a ball-on-disk-type oscillating tribometer,under wet conditions using physiological solution in accordance with the ISO7148 standards.The tests were carried out under a normal load of 6 N,with an AISI 52100 grade steel ball as a counter face.The morphological changes and structural evolution of the nanoparticle powders using different milling times(2,6,12 and 18 h)were studied.The morphological characterization indicated that the particle and crystallite size continuously decrease with increasing milling time to reach the lowest value of 4 nm at 18-h milling.The friction coefficient and wear rate were lower in the samples milled at 18 h(0.226,0.297 and 0.423;and 0.66 9 10^(-2),0.87 9 10^(-2)and 1.51 9 10^(-2)lm^3N^(-1)lm^(-1))for Ti–6Al–4Fe,Ti–6Al–7Nb and Ti–6Al–4V,respectively.This improvement in friction and wear resistance is attributed to the grain refinement at 18-h milling.The Ti–6Al–4Fe samples showed good tribological performance for all milling times. | Mamoun Fellah Linda Aissani Mohammed Abdul Samad Alain Iosts Touhami Mohamed Zine Alex Montagnes Corinne Nouveau | 2017 | Acta Metallurgica Sinica(English Letters)2017，30，11： | 1 |

| 3 | 烧结温度对生物医用纳米Ti-15Mo合金组织和摩擦学性能的影响(英文)显示文摘研究烧结温度(1073~1373 K)对具有纳米结构的球磨β型Ti-15Mo合金结构和摩擦学性能的影响。通过多种技术对试样进行表征,如X射线衍射分析(XRD)、电子扫描电镜(SEM)和球盘式往复摩擦试验机等;采用不同载荷(2、8和16 N)进行磨损试验。结果表明,随着烧结温度的升高,合金的平均孔径和晶粒尺寸不断减小,在1373 K时分别达到最低值:4 nm和29 nm,1373 K烧结样品的相对密度高达97.0%。此外,烧结温度越高,试样的相对密度越大、硬度越高、弹性模量越高;1373 K烧结试样由于其较低的闭孔率导致摩擦因数和磨损率也较低。 | Mamoun FELLAH Naouel HEZIL Dekhil LEILA Mohammed ABDUL SAMAD Ridha DJELLABI Stephania KOSMAN Alex MONTAGNE Alain IOST Aleksei OBROSOV Sabine WEISS | 2019 | Transactions of Nonferrous Metals Society of China2019，29，11： | 0 |
