Detailed Microstructural Evolutions of TWIP Steel During Tensile Straining: In situ SEM Observations

Microstructural evolutions of twinning induced plasticity (TWIP) steel during tensile straining were investigated by in situ SEM observations. The results indicated that slip lines and mechanical twins as well as surface relief were increased with increasing strain, resulting in a stepped surface. Additionally, these deformation mechanisms could change the shape of each grain via shear and rota...

Interaction on human-centric communication platforms: modelling and analysis using algebraic high-level nets and processes

Human-centric communication platforms, like social networks such as Facebook or Twitter, weblogs, Wiki-systems or Apache Wave, are systems that support humans to communicate, collaborate interactively, and exchange content. Over the last years, modern communication systems have evolved to provide different more interactive ways of communication, where several users have the possibility to concu...

Property Based Verification of Evolving Petri Nets

Abstract—Software evolution is inevitable in the field of information and communication technology systems. Existing software systems continue to evolve to progressively reach important qualities such as completeness and correctness. Iterative refinements and incremental developments are considered to be well suitable for the development of evolving systems among other approaches. The problem w...

The Effect of Deformation Temperature on the Mechanical Properties and Microstructural Evolutions of High Manganese TWIP Steel

In this study, the effect of tensile test temperature (148 to 673 K) on the microstructural evolutions and the mechanical properties of high manganese twinning induced plasticity (TWIP) steel with the chemical composition of Fe- 31Mn-3Al-3Si (wt. %) was investigated. XRD, SEM and TEM were used to study the microstructural evolutions. Stacking fault energy (SFE) of the alloy was also calculated ...

Integration of distributed spatial data in a decision making context

The widespread deployment of communication networks has facilitated the sharing and exchange of spatial data between producers and users spread out over different locations. These users are not necessarily located at the same sites neither belong to the same organizations, but must cooperate. Spatial data is used to help user making decision in this context. Data is updated in parallel, dependi...
