Book Description
Quantitative relationships among processing parameters, microstructure, and material properties are of considerable interest in the context of development of robust processing routes that optimize the required material properties. As a result, the scientific literature contains a large number of experimental and theoretical studies on microstructure-properties relationships. Fracture sensitive mechanical properties such as ductility, ultimate tensile strength, fatigue life, and fracture toughness depend on the average microstructural parameters as well as the distributions of microstructural parameters and their extrema. Development of quantitative relationships between such material properties and microstructural distributions and extrema has received considerably less attention, particularly in the wrought metals and alloys. Accordingly, an important objective of this research is to perform a systematic investigation in this direction. The dependence of the fracture-sensitive mechanical properties on the microstructural distributions and extrema often leads to substantial variability in these properties: a set of specimens having the same average chemistry, the same average processing history, and the same average microstructural parameters such as volume fractions of different constituents can exhibit substantially different material properties. The present research (i) is concerned with high strength (~ 1000 MPa) high martensite (>50%) dual phase steel where the martensite is a topologically continuous phase (matrix) containing a dispersion of islands of ferrite, and (ii) focuses on understanding the microstructural origins of the variability in fracture sensitive mechanical properties, in particular variability in the room temperature uniaxial tensile ductility. The research involves quantitative microstructure characterization using stereology and digital image processing and quantitative fractography using scanning electron microscopy (SEM) and fracture profilometry. The analysis of the quantitative fractographic and microstructural data obtained in this research leads to useful guidelines for reducing the variability in the tensile ductility of the dual phase steel under investigation.

Work-hardening of dual-phase steel
Author: Rieger, FlorianPublisher: KIT Scientific Publishing
ISBN: 3731505134
Category : Technology (General)
Languages : en
Pages : 202
Book Description
Dual-phase steels exhibit good mechanical properties due to a microstructure of strong martensitic inclusions embedded in a ductile ferritic matrix. This work presents a two-scale model for the underlying work-hardening effects; such as the distinctly different hardening rates observed for high-strength dual-phase steels. The model is based on geometrically necessary dislocations and comprises the average microstructural morphology as well as a direct interaction between the constituents.
Crystal Plasticity
Author: Wojciech PolkowskiPublisher: MDPI
ISBN: 3036508384
Category : Science
Languages : en
Pages : 438
Book Description
The book presents a collection of 25 original papers (including one review paper) on state-of-the art achievements in the theory and practice of crystals plasticity. The articles cover a wide scope of research on materials behavior subjected to external loadings, starting from atomic-scale simulations, and a new methodological aspect, to experiments on a structure and mechanical response upon a large-scale processing. Thus, a presented contribution of researchers from 18 different countries can be virtually divided into three groups, namely (i) “modelling and simulation”; (ii) “methodological aspects”; and (iii) “experiments on process/structure/properties relationship”. Furthermore, a large variety of materials are investigated including more conventional (steels, copper, titanium, nickel, aluminum, and magnesium alloys) and advanced ones (composites or high entropy alloys). The book should be interested for senior students, researchers and engineers working within discipline of materials science and solid state physics of crystalline materials.

X-Ray Diffraction Studies on the Deformation and Fracture of Solids
Author: Kazuyoshi TanakaPublisher: Elsevier
ISBN: 1483290387
Category : Technology & Engineering
Languages : en
Pages : 338
Book Description
This volume covers current research findings and engineering applications of X–ray methods by the Japanese X–ray group members. The first part of the volume deals with fundamental problems in the methods for X–ray stress measurement. Phase stresses in the constituent phases of ceramic composites and ceramic-fiber reinforced metal-matrix composites are separately measured by X–rays, while three-dimensional stresses and thermal stresses in composites measured by X–rays are compared with the theoretical and numerical analyses. This work will therfore provide significant information for designing high-performance composites. Other topics covered include synchrotron X–ray radiation and the analysis of X–ray data by the Guassian curve method. Part two is devoted to the application of X–ray diffraction methods for various engineering purposes, the residual stress and half-value breadth (the full width at half the maximum) of the diffraction profiles being the two main X–ray parameters utilized in those applications. Chapters are included on X–ray fractography, a powerful technique for failure analysis, which is applied to the brittle fracture of ceramics and to the fatigue fracture of steels under various service conditions.
