The influence of the as-cast and fully heat-treated microstructures on isothermal behaviour Ni-based single crystal superalloy AM1 was investigated at 8501050 °C. It appears that kinetics transition regime is a function time, temperature also bulk microstructure. various characterisation techniques allowed elucidating growth continuous inner layer α-Al2O3 governs oxidation mechanisms, irrespective Such favoured for high temperatures, long exposure times γ' precipitate surface fraction....
Abstract Recently, considerable effort has been devoted to the development of so‐called meshless methods. Meshless methods still require improvement before they equal prominence finite elements in computer science and engineering. One paths evolution element free Galerkin (EFG) method. In EFG method, it is obviously important that ‘ a posteriori error’ should be approximated. An approximation based on moving least‐squares method proposed, using solution, computed from The error procedure...
Details are given of equipment which has been used to prepare and mechanically test single crystal specimens beryllium from zone refined rod. An electrolytic etching machine is described whereby the test-pieces may be prepared without mechanical deformation, details a modified Polanyi apparatus in tested tension at temperatures up about 600 °C.
High-purity beryllium powder possesses characteristics differing substantially from those of the normal that until recently has been purest form available. These are compared and discussed, together with methods for consolidating treating compacts. The techniques available fabricating porous compacts their applicability also described.
The paper surveys the existing routes available for preparation of beryllium powders, and comments on effect certain properties, such as particle-size distribution, compaction powders by different techniques. It is emphasized that particle size, degree oxidation, overall purity are interdependent variables, little attempt has so far been made to study their effects separately.
