Effects of structure characteristics on mechanical properties of aluminum alloy matrix composites
(Trans Tech Publications Ltd, 2004)
Composite materials based on the CW67 alloy (Al base matrix) and volume fraction of 15 pet of SiC particles in two nominal sizes (0.7 μm and 33 μm) have been produced by hot pressing. The fracture behavior of the composite ...

Crystallographic orientations of Ni3Al-based aluminide
(Elsevier Science Inc, New York, 2000)
Inverse pole figures have been plotted to determine preferred crystallographic orientations in a powder-compacted Ni3Al aluminide prealloyed with Fe, Ti and B. The main textural components, although weak, were noticeably ...
Microstructure and toughness of CuNiMo austempered ductile iron
(Elsevier, Amsterdam, 2004)
The effect of austempering on the microstructure and toughness of nodular cast iron (designated as CuNiMoSG) alloyed with molybdenum, copper, nickel, and manganese has been studied. Light microscopy (LM), scanning electron ...
Analysis of the unstable fracture behaviour of a high strength low alloy steel weldment
(Pergamon-Elsevier Science Ltd, Oxford, 2004)
Local brittle zones (LBZ) cause the unstable fracture behaviour of weld metals. This threatens the safe service of welded structures and makes structural assessment procedures difficult. Therefore, the unstable fracture ...
Micromechanical coupled study of crack growth initiation criterion in pressure vessel steel
(Strength of Materials, 2004)
We present results of the combined design-theoretical investigation of the mechanism of crack growth at the onset of ductile fracture of NPP reactor pressure vessels. Micromechanical approach to the prediction of ductile ...
Optimization of elevator regimes of movement
(China Machine Press, Beijing, 2004)
The paper presents the procedure for determining the optimal regimes of movement of the elevator cabin as a function of input values such as: distance that elevator cabin has to pass, acceleration, velocity and jerk of the ...
New modular concept for the helium cooled pebble bed test blanket module for ITER
(Elsevier Science Sa, Lausanne, 2005)
Starting from the latest European design of the HCPB blanket for the DEMO a test blanket module for ITER has been deduced. The paper describes the new design and presents the rational of the design choices and the results ...
Weldability testing of microalloyed steel and integrity assessment of welded joint
(Institut International de la Soudure, 2005)
The results of weldability assessment of high strength low carbon microalloyed steel are presented. These results are used for integrity assessment of weldments. Two aspects of behaviour were considered. These are the risk ...
Prediction of ductile fracture initiation using micromechanical analysis
(Pergamon-Elsevier Science Ltd, Oxford, 2004)
In the paper ductile fracture initiation analysis of low-alloyed ferritic steel has been made by application of two micromechanical models: the Rice-Tracey void growth model and the Gurson-Tvergaard-Needleman (GTN) model. ...
