This atlas is a collection of continuous cooling transformation diagrams applicable to low carbon low alloy weld metals. It will be of assistance to welding engineers, welding metallurgists, welding-consumables designers in industry.

Research goal of the present monograph is the establishment of an efficient engineering approach, which will include straightforward but accurate simulation models, in order to estimate the residual stress fields of welded joints introduced during welding and their post-weld treatment with High Frequency Hammer Peening. The present subject lies on the intersection of structural engineering, material science and computational mechanics.

The issue “Applied Mechanics and Mechatronics” contains results of research from researchers and designers from several prominent universities and research institutes of Central Europe. The publication is divided into three following chapters: Modeling and Simulation of Mechanic and Mechatronic Systems Analysis and Design of Mechanic and Mechatronic Systems Experimental methods in Mechanics and Mechatronics. The submitted publication provides insight on modern approaches and methods in designing, modeling and experimental analyzing of mechanic and mechatronics systems.

The microstructures of both martensite and bainite, although sharing some common features, depict a plethora of subtle differences that made them unique when studied in further detail. Tailoring the final properties of a microstructure based on one or the other as well as in combination with others and exploring more sophisticated concepts, such as Q&P and nanostructured bainite, are the topics which are the focus of research around the world. In understanding the key microstructural parameters controlling the final properties as well as definition of adequate process parameters to attain the desired microstructures requires that a proper understanding of the mechanism ruling their transformation and a detailed characterization first be acheived. The development of new and powerful scientific techniques and equipment (EBSD, APT, HRTEM, etc.) allow us to gain fundamental insights that help to establish some of the principles by which those microstructures are known. The developments accompanying such findings lead to further developments and intensive research providing the required metallurgical support.
