| 1 | Hot Compression Behavior of As-Cast Precipitation-Hardening Stainless Steel显示文摘High temperature deformation characteristics of a semiaustenitic grade of precipitation-hardening stainless steels were investigated by conducting hot compression tests at temperatures of 900-1 100 ℃ and strain rates of 0.001-1 s-1. Flow behavior of this alloy was investigated and it was realized that dynamic recrystallization (DRX) was responsible for flow softening. The correlation between critical strain for initiation of DRX and deformation parameters including temperature and strain rate, and therefore, Zener-Hollomon parameter (Z) was studied. Metallographic observation was performed to determine the as-deformed microstructure. Microstructural observation shows that recrystallized grain size increases with increasing the temperature and decreasing the strain rate. The activation energy required for DRX of the investigated steel was determined using correlations of flow stress versus temperature and strain rate. The calculated value of activation energy, 460 kJ/mol, is in accordance with other studies on stainless steels. The relationship between peak strain and Z parameter is proposed. | A Momeni S M Abbasi A Shokuhfar | 2007 | Journal of Iron and Steel Research(International)2007，14，5： | 9 |
| 2 | Improvement of Mechanical Properties of Cr-Ni-Mo-Cu-Ti Stainless Steel With Addition of Vanadium显示文摘The effect of vanadium (V) addition on the mechanical properties of a Cr-Ni-Mo-Cu-Ti stainless steel was studied and its influence on microstructural changes was also investigated. Results indicate that the structure of the solution-treated specimens mainly comprises of austenite-martensite, and adding V leads to the formation of a considerable amount of ferrite. Under this condition, austenite phase is not mechanically stable, and transforms to martensite by plastic deformation. The addition of 0.5% - 1.0% (in mass percent) of V increases the hardness and the strength of the 80% cold rolled and aged steel, without any effect on ductility. Improvement in mechanical properties is presumably attributed to the formation of a small amount of ferrite in the primary structure, and the formation of certain precipitates is accelerated by the addition of V during aging. By contrast, excessive V decreases the strength and ductility simultaneously. This is due to the strong effect of ferrite formation compared to the beneficial effect of precipitation. The loss of ductility caused by adding higher amount of V is due to the formation of ferrite phases which in turn are suitable nucleation sites for crack propagation. | S M Abbasi A Shokuhfar | 2007 | Journal of Iron and Steel Research(International)2007，14，6： | 7 |
| 3 | Mechanisms of fibrinolysis resistance and potential targets for thrombolysis in acute ischaemic stroke: lessons from retrieved stroke emboli显示文摘There has been growing interest and insight into the histological composition of retrieved stroke emboli.One of the main focuses of the stroke clot analysis literature has been the implications of clot composition on mechanical thrombectomy procedures.However,the holy grail of clot analysis may not be in the field of clot-device interaction,but rather,in understanding mechanisms of fibrinolysis resistance.The mechanisms underlying the low response to fibrinolytic therapy,even with the newer,more powerful agents,remain poorly understood.While factors such as embolus size,location and collateral status influence alteplase delivery and recanalisation rates;compositional analyses focused on histological and ultrastructural characteristics offer unique insights into mechanisms of alteplase resistance.In this review,we strive to provide comprehensive review of current knowledge on clot composition and ultrastructural analyses that help explain resistance to fibrinolysis. | Waleed Brinjikji Oana Madalina Mereuta Daying Dai David F Kallmes Luis Savastano Yang Liu Shahid M Nimjee Raul G Nogueira Mehdi Abbasi Ramanathan Kadirvel | 2021 | Stroke & Vascular Neurology2021，6，4： | 2 |
