Due to the high weld temperature(exceeding the β-transus) and high cooling rate, β→α' martensitic transformation occurs. Within the fusion zone, only acicular morphology exists, while in 1st heat affected zone(HAZ) and 2nd HAZ, these acicular laths globalize, which show an obvious microstructural gradient. The result of the in-situ plastic deformation shows the deformation can be divided into 2 stages. In the first stage of the deformation, either slipping or twinning can occur. It depends on whether the initial orientation can respect //TA(tensile axis) by rotating the grains or not. While in the second stage, only slipping can be found. © 2019, The Editorial Board of Materials China.

The efficient bone tissue repair and regeneration have been important topics in clinical medicine. Here,biomedical materials play an important role in bone regeneration. However,current clinical bone-repair biomaterials such as autografts,allografts and synthetic materials( metals,ceramics and polymers) suffer from various shortcomings,having limited applications in bone repair. In bone tissue engineering research,biodegradable scaffolds along with cells and growth factors have shown high potential in facilitating bone regeneration as a potential new therapy for bone loss in the clinic. In the past decade,due to their structure and morphology that mimic the native extracellular matrix,nanofibrous scaffolds have been shown to be capable of facilitating cell proliferation,osteogenic differentiation of stem cells,and bone regeneration in vivo compared to control scaffolds. In this paper,we will review the fabrication technologies of biomimetic nanofibrous scaffolds and their applications in enhancing cellular function,osteogenic differentiation,and bone tissue regeneration.","PeriodicalId":53495,"journal":{"name":"Materials China","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71345168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These technologies are based on the complex photosensitive image process. The exposing and development processes result in waste of photosensitive materials and environment pollution. Green plate making technology is not based on photosensitive materials but nano-materials. The image process of the technology is to jet the nano-composite transfer printing material on super hydrophilic print plate with special nano and micro-structure. Then the oleophilic image area and hydrophilic non image area are formed by adjusting interface characters between the nano-composite transfer printing material and super hydrophilic print plate. The plate is used for printing without exposing and development. Without photosensitive image process, the technology has many advantages such as no operation in darkroom, simple process, environmental friendly and low cost. The key problems of print resolution and press life have been solved effectively by preparation of nano composite transfer printing material and super hydrophilic print plate. In this paper, the research process of the nano composite material and the print plate are presented.","PeriodicalId":53495,"journal":{"name":"Materials China","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4028/www.scientific.net/AMR.174.447","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70642318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
