內(nèi)容概要

　　第十二屆鈦會(huì)是系列會(huì)議的第十二屆，鈦會(huì)自1968年開(kāi)始，每四年舉辦一次，旨在召集世界鈦界同仁，共商鈦科技發(fā)展大計(jì)。鈦會(huì)覆蓋了鈦的各個(gè)方面，包括從礦石到成品的完整的生產(chǎn)路線(xiàn)，新合金和加工的發(fā)展，微觀(guān)結(jié)構(gòu)和性能的評(píng)價(jià)以及所有領(lǐng)域鈦的應(yīng)用。世界七大鈦國(guó)，包括美國(guó)、俄羅斯、日本、英國(guó)、法國(guó)、中國(guó)和德國(guó)組成的國(guó)際組織委員會(huì)保證了鈦研究、發(fā)展和應(yīng)用的各個(gè)新的、感興趣領(lǐng)域都將被討論。

章節(jié)摘錄

　　Based on the con-ventional methods mentioned above， a novel approachthat measuring the mean thickness of a laths in colonyusing Boolean operation is proposed in this work，which is shown in Figure 1. The feature parameters of micro-structures in titanium alloys extracted using this meth-od include phase volume fraction，grain size，thickness of Widmanstatten a laths， colony scale size， thickness and orientation of a phase. It not only reduces the errorwhich is associated with the lineation by users but alsoenhances the reliability of measured data. Moreover，inorder to unify the measurement standard of a phase in the basket weave，mixed and equiaxed microstructures of typical titanium alloys and take the continuity andsimplicity of quantification into consider ation，the eval-uated parameter of Feret Ratio was referred to present the evolution of c， phase and modeling the correlation of process，microstructure and mechanical property of ti-tanium alloys. The orientation of a phase was presentedby the angle to the primary axis of a phase and its ver-tical direction，which suggests that the characterizationmodel of evolution and orientation behavior in a phaseduring hot deformation of titanium alloys has been es-tablished，as shown in Figure 2. It should be noted that the proposed model has been successfully applied toquantitatively exhibit the dynamic evolution of a phase in TC17 titanium alloy with lamellar microstructure.Hence，the realization of quantification characterization about the evolution of lamellar a phase takes place of the traditional method that whether the globularizationphenomenon occurred.In the present in vestigation，with the help of the basic theory of stereology and quantitative metallogra-phy and analysis platform of quantification image soft-ware，a rigorous and available model of quantification of microstructural features was developed. Previously，the phase volume fraction was measured using area meth-od，and the mean intercept method was employed tome asure the grain and colony size.　　……
