| 1 | Effect of alloying elements on austempered ductile iron(ADI) properties and its process:Review显示文摘Austempered ductile iron(ADI) parts have a unique combination of high strength and toughness with excellent design flexibility and low cost. These excellent properties are directly related to its microstructure called 'ausferrite' that is the result of austempering heat treatment applied to ductile irons. Alloying elements increase ADI austemperability and change speeds of austempering reactions. Thus, they can affect ADI resultant microstructure and mechanical properties. In this paper, the effects of alloying elements on ADI mechanical properties, microstructural changes, two-stage austempering reactions, processing windows, austemperability, and other aspects are reviewed. | Amir Sadighzadeh Benam | 2015 | China Foundry2015，12，1： | 3 |
| 2 | Comparison between the SAPIEN S3 and the SAPIEN XT transcatheter heart valves:A single-center experience显示文摘AIM To investigate the clinical outcomes of transcatheter aortic valve implantation(TAVI) with the SAPIEN 3 transcatheter heart valve(S3-THV) vs the SAPIEN XT valve(XT-THV).METHODS We retrospectively analyzed 507 patients that underwent TAVI with the XT-THV and 283 patients that received the S3-THV at our institution between March 2010 and December 2015.RESULTS Thirty-day mortality(3.5% vs 8.7%:OR=0.44,P=0.21) and 1-year mortality(25.7% vs 20.1%,P=0.55) were similar in the S3-THV and the XT-THV groups.The rates of both major vascular complication and paravalvular regurgitation(PVR)>1 were almost 4 times lower in the S3-THV group than the XT-THV group(major vascular complication: 2.8% vs 9.9%,P<0.0001:PVR>1: 2.4% vs 9.7%,P<0.0001).However,the rate of new pacemaker implantation was almost twice as high in the S3-THV group(17.3% vs 9.8%,P=0.03).In the S3 group,independent predictors of new permanent pacemaker were pre-procedural RBBB(OR=4.9:P=0.001),pre-procedural PR duration(OR=1.14,P=0.05) and device lack of coaxiality(OR=1.13:P=0.05) during deployment.CONCLUSION The S3-THV is associated to lower rates of major vascular complications and PVR but higher rates of new pacemaker compared to the XT-THV.Sub-optimal visualization of the S3-THV in relation to the aortic valvular complex during deployment is a predictor of new permanent pacemaker. | Fadi J Sawaya Marco Spaziano Thierry Lefèvre Andrew Roy Phillippe Garot Thomas Hovasse Antoinette Neylon Hakim Benamer Mauro Romano Thierry Unterseeh Marie-Claude Morice Bernard Chevalier | 2016 | World Journal of Cardiology2016，8，12： | 2 |
| 3 | 喷丸强化对合金化奥贝球铁疲劳性能的影响显示文摘喷丸处理是改进金属工件疲劳性能最常规的表面处理方法。文中研究了喷丸处理对合金化奥贝球铁(AD)I疲劳性能的影响。等温淬火包括875℃保温90 min奥氏体化处理,然后在320℃、365℃和400℃进行等温处理。用直径0.4~0.6 mm的丸喷丸后的试样做旋转弯曲疲劳试验。对试样进行XRD和SEM分析,测定显微硬度和粗糙度,研究试样的疲劳性能。结果表明,在320℃、365℃和400℃等温处理的试样喷丸后疲劳强度分别增加了27.3%、33.3%和48.4%。 | Amir Sadighzadeh Benam Sasan Yazdani Behzad Avishan | 2012 | 铸造2012，61，2： | 2 |
| 4 | Effect of shot peening process on fatigue behavior of an alloyed austempered ductile iron显示文摘Shot peening is one of the most common surface treatments to improve the fatigue behavior of metallic parts. In this study the effect of shot peening process on the fatigue behavior of an alloyed austempered ductile iron (ADI) has been studied. Austempering heat treatment consisted of austenitizing at 875℃ for 90 min followed by austempering at three different temperatures of 320, 365 and 400℃. Rotating-bending fatigue test was carried out on samples after shot peening by 0.4-0.6 mm shots. XRD and SEM analysis, micro hardness and roughness tests were carried out to study the fatigue behavior of the samples. Results indicate that the fatigue strengths of samples austempered at 320, 365 and 400℃ are increased by 27.3%, 33.3% and 48.4%, respectively, after shot peening process. | Amir Sadighzadeh Benam Sasan Yazdani Behzad Avishan | 2011 | China Foundry2011，8，3： | 2 |
