| 1 | Effects of Zr on Microstructure and Short-TermStrength in GH586显示文摘0.020, 0.045 and 0.075 wt pct Zr were added to a Ni-base superalloy GH586 to investigate theirefFects on the microstructure and the short-term strengths at 850℃. The results showed thatproper Zr addition could improve the alloy tensile strength at 850℃ and short-term rupture life at850℃, 580 MPa. Zr exists in both γ’ phase and γ matrix, which caused Zr to distribute in graininstead of segregating in grain boundaries, therefore increased both of their lattice parametersbut decreased the mismatch between them. Meanwhile, it also increased the amount of grain-boundary carbides and decreased their size markedly. These contributed to the improvement ofshort-term rupture life. However, further addition of Zr resulted in forming Zr4C2S2, a plate-fike stable sulphurocarbides in grain boundaries, which decreased short-term strength at hightemperature, and led to a worse hot workability. According to the experimental results, theoptimum content of Zr should be 0.020 wt pct. | Xie, SS Wang, TL Lu, JY Yang, HC Zhao, GP | 1999 | Journal of Materials Science & Technology1999，15，5： | 3 |
| 2 | Similarities and differences in clinical and pathologic features of inflammatory bowel disease-associated colorectal cancer in China and Canada显示文摘Background:Colorectal cancer(CRC)has become one of the major life-threatening complications in patients with inflammatory bowel disease(IBD),which includes ulcerative colitis(UC)and Crohn's disease(CD).This study aimed to explore the clinicalpathologic similarities and differences in the IBD-associ吐ed CRC(IBD-CRC)between patients in China and Canada.Methods:Data of 78 patients with IBD-CRC retrospectively retrieved from two representative medical institutions in Beijing(China)and Calgary(Canada)over the same past 13 years,including 25(22 UC-associated and three CD-associated)from Beijing group and 53(32 UC-associated and 21 CD-associated)from Calgary group,were compared with regards to their clinical and pathologic characteristics.Results:Several known features of IBD-CRC were seen in both groups,including long duration and large extent of colitis,active inflammation background,multifocal lesions,and advanced tumor-node-metastasis stage.Beijing group showed a significantly higher percentage of UC(88.0%vs.60.4%,P=0.018),younger age at diagnosis of CRC(48.6±12.8 years vs.61.6±14.7 years,P<0.001),lower ratio of mucinous adenocarcinoma(7.1%us.42.4%,P=0.001)compared with Calgary group.None of the Beijing group had concurrent primary sclerosing cholangitis,while 5.7%of Calgary group did.Surveillance colonoscopy favored the detection rate of precancerous lesions(41.4%vs.17.0%,P=0.002).Conclusions:As compared with patients from the Calgary group,the IBD-CRC patients in Beijing group were younger,less CDassociated and had less mucinous features,otherwise they were similar in many common features. | Ji Li Wei-Xun Zhou Shuang Liu Wei-Yang Zheng Ya-Nan Wang Jing-Nan Li Jose Gp Ferraz Jia-Ming Qian Xian-Yong Gui | 2019 | Chinese Medical Journal2019，，22： | 2 |
