Solidification Structure Refining of 430 Ferrite Stainless Steel With TiN Nucleation

引用

Journal of Iron and Steel Research International 2008年第3期15卷 57-60页

作者： shi cai-xia CHENG Guo-guang LI Zhan-jun ZHAO Pei University of Science and Technology Beijing Beijing 100083 China Central Iron and Steel Research Institute Beijing 100081 China

The thermodynamics of TiN precipitation in liquid steel of 430 ferrite stainless steel has been calculated to find out the condition of TiN precipitation during the initial solidification stage. The difference in the solidification structure of 430 ferrite stainless steel has been discussed through comparative tests of vacuum induction furnace melting with different contents of Ti. It has been found that the equiaxed grain proportion can be increased from 20% to 69% as the content of Ti from 0.1% up to 0. 4%. The size of the TiN particles precipitated is 1-3 μm and the number of TiN particles is about （200- 300）/μm^2. It is found that the effect of using TiN to refine the solidification structure has been confirmed under the strict process condition used for 430 ferrite stainless steel.

A file format for storage of scalable video is proposed. A generic model is presented to enable a codec independent description of scalable video stream. The relationships, especially the dependencies, among sub-streams in a scalable video stream are specified sufficiently and effectively in the proposed model. Complying with the presented scalable video stream model, the file format for scalable video is proposed based on ISO Base Media File Format, which is simple and flexible enough to address the demands of scalable video application as well as the non-scalable ones.

We are optimistic about Professor Shukui Qin and colleagues’electrifying results regarding the efficacy and safety of donafenib(a modified form of sorafenib)over sorafenib in treating advanced hepatocellular carcinoma(aHCC)(1).Following the landmark sorafenib trial in 2008(2),the present ZGDH3 trial is the first and only first-line head-to-head phase 2-3 trial to demonstrate that monotherapy is superior to sorafenib in terms of overall survival(OS)for *** the ZGDH3 trial,Qin et *** assigned 668 eligible patients to receive 200 mg of donafenib or 400 mg of sorafenib,orally,twice daily,with open-label administration[donafenib(n=334),sorafenib(n=334)].The primary endpoint was OS and secondary endpoints included progression-free survival(PFS),time to progression,objective response rate(ORR),disease control rate(DCR),survival rates at 6,9,12,and 18 months,and safety.
