MICROSTRUCTURE FORMATION DURING SOLIDIFICATION AND SOLID STATE TRANSFORMATION IN COMPACTED GRAPHITE IRON SUPPLEMENTS The following supplements constitute the basis of this thesis. The supplements denotations and references are followed by a description of the distribution of work. Effects of Geometric Constraints on Alloy Solidification in Metal-Matrix Composites: Modeling of Ferrite Growth in Compacted Graphite Iron: A Combined Experimental-Model Approach to Estimate the Solidification Macrostructures Formed During a Microgravity Experiment on Ti-Al Based Intermetallic Alloys.

Formation of solidification microstructures. Mushy zone dynamics (e.g., solidification kinetics in presence of inter-grain interactions, hydrodynamics, rheology). Heat and mass transfer and fluid flow at the process scale and the links to microstructure and defect formation (segregation, porosity, deformation and hot tearing) during solidification. A careful observation however shows a higher inhomogeneity of these composites with respect to the pure aluminium alloy, suggesting that the presence of nano-MgAl 2 O 4 particles changes the behavior during solidification. This inhomogeneity, together with the higher residual porosity, reflects on the values of Brinell Hardness, that is 93 ± 3 Cited by:

Metal matrix composites (MMCs) are the new generation materials that combine both the metallic properties (ductility and toughness) and ceramic characteristics (high strength and modulus), leading to higher strength in shear and compression, at higher service temperatures. Titanium matrix composites possess light weight, high strength and good corrosion resistance and are Cited by: 4.   This paper focuses on the role played by the liquid metal management on the solidification microstructure in industrial solidification processes. In particular attention is paid to the elimination of solidification defects by governing the microstructure evolution through fluid-dynamics and heat and mass transport in the liquid. The formation of hot tearing and gas Cited by: 1.

The microstructure of a particulate-filled polymer (see Fig. 1) is characterized by two main parameters: the filler volume fraction, Φ=V f /V c, where the subscripts f and c refer to filler and composite, respectively, and V is volume; and the average particle diameter, d, or the average interparticle distance, D (these two parameters are interrelated for a given Φ f and filler particle.

Solidification microstructures of aluminium silicon alloy (A) containing 0, 10, 15 and 20 vol % silicon carbide particles formed during directional solidification from a chill have been studied and compared with the structures obtained during solidification of the base alloy under similar mould and chill conditions.

The microstructures that develop during the solidification of stainless steel alloys are related to the solidification conditions and the specific alloy composition. The solidification conditions are determined by the processing method,i.e., casting, welding, or rapid solidification, and by parametric variations within each of these techniques.

One variable that has been used Cited by: From the above literature review, it is clear that the in-situ formation of TiC particle metal matrix composites through laser cladding is a feasible process.

Furthermore, it is widely reported that the hardness and wear resistance of the substrate can be significantly enhanced by the formation of a TiC-based composite by: 7. Microstructure Formation During Solidification of Metal Matrix Composites by P.K.
