Abstract: Isothermal compression tests of BSTMUF601 super-alloy in the temperature range of 950 ̋C–1200 ̋C and at the strain rates of 0.2 s ́1, 5 s ́1, 10 s ́1 were performed on a Gleeble-1500D thermo-mechanical simulator. Based on the hyperbolic sine function, the unified constitutive equations and hot processing maps during the hot deformation process were established. The flow stress predicted by...

The hot deformation behaviour of austenite in steels is a complicated process which depends on chemical composition, microstructure, temperature and strain rate. While many models have been developed to represent the flow stress as a function of these variables, it is not yet possible to predict the behaviour for a new alloy. Linear regression techniques are not capable of representing the data...

In large area micro hot embossing, process temperature plays a critical role in both the local fidelity of microstructure formation and global uniformity. Micro embossing at the lowest temperature with acceptable fidelity can improve the global flatness after demolding. This paper focuses on polymer deformation and recovery in micro embossing when the process temperatures are below its glass tr...

The paper focuses on the void swelling processes in materials subjected to radiation, that occur due formation of ensemble crystal lattice. According theoretical analysis kinetics and pore size distribution with regard defect migration, numerical calculations are performed for nickel.
