| 1 | EFFECT OF RESIDUAL STRESS ON THE MARTENSITIC TRANSFORMATION OF SPUTTER-DEPOSITED SMA THIN FILMS显示文摘TiNi thin films were sputter-deposited on circular single-crystal silicon substrates un-der various sputtering parameters. The crystal structure and residual stress of the as-deposited films were determined by X-ray diffraction and substrate-curvature method.The phenomenon of stress-suppressed martensitic transformation was observed. It isconsidered that the residual stresses in SMA thin films based on circular substratesact as balanced biaxial tensile stresses. The status of equilibrant delays the align-ment of self-accommodated variants and the volume shrinkage during the martensitictransformation. | L.Wang,D.Xu and B.C.CaiInformation Storage Research Center, Shanghai Jiao Tong University, Shanghai 200030, China Manuscript received 14 September 2001 in revised form 27 November 2001 | 2002 | Acta Metallurgica Sinica(English Letters)2002，15，4： | 3 |
| 2 | CONSTITUTE EQUATIONS OF 40Cr STEEL UNDER SUPERPLASTIC COMPRESSIVE DEFORMATION显示文摘The microstructure of 40Cr steel sample and its surface is ultra-fined through saltbath cyclic quenching and high frequency hardening, then the superplasticity is studied under isothermal superplastic compressive deformation condition. The experimental results indicate that the stress-strain curves are shown to take place obvious superplastic flow characteristic at the temperature of 730-770℃ and at the initial strain rate of (1.7-5.0)× 10-4s-1. Its strain rate sensitivity is 0.30-0.38, the steady superplastic flow stress is 60-70MPa, the superplastic flow activation energy is 198-217kJ/mol,and it is close to α-Fe grain boundary self-diffusion activation energy. The superplastic compressive constitute equations of this steel are correspondingly set up. Due to the finer microstructure of high frequency hardening, it appears bigger strain rate sensitivity value, smaller the steady superplastic flow stress and the superplastic flow activation energy, so it has better superplastic deformation capability. | K.K.Zhang Y.L.Yang S.Z.Liu C.X.Han D.Xu | 2003 | Acta Metallurgica Sinica(English Letters)2003，16，6： | 3 |

| 12 | The RQ-Tech methodology:a new paradigm for conceptualizing strategic enterprise architectures显示文摘The purpose of this paper is to report on a new system-theoretic based methodology and corresponding model for Enterprise Architecture development.This model captures the essence of the strategic,conceptual,doctrinal layer of the organization.Reusable Quality Technical Architectures(RQ-Tech)graphically reveals a comprehensive array of enterprise decision alternatives in easily understandable views;all while maintaining the hyperlinks to its provenance in strategic authoritative documentation.The RQ-Tech method has combined the practice of Enterprise Architectures with a modern perspective grounded in Systems Theory and the theory regarding the computer science-oriented Semantic Web.This recombination results in a distinctive methodology for developing models.This new methodology supports the conclusion that system-specific solutions produce islands of technology and can be prevented by employing better enterprise change planning.A review of the literature in three major areas illustrates the overlap common to all three domains.This review provides support for critical thinking concerning how to enrich the Enterprise Architecture practice.The research centered on finding the most significant factors to consider when translating the authoritative text and rich pictures that enterprise managers use to describe the strategic mission and vision of their complex,service-oriented enterprise into user-oriented semantic models.It provides the basis for RQ-Tech as a methodology that enables increased understanding of complex systems through use of Semantic Web standards. | Christine A.Hoyland Kevin M.Adams Andreas Tolka Li D.Xu | 2014 | Journal of Management Analytics2014，1，1： | 0 |
