Technological plasticity and structure in stainless steels during hot-working
Metallic alloys Hot deformation Microstructure
2009/12/14
Purpose: The high-temperature plastic deformation is coupled with dynamic processes of recovery influencing the structure and properties of alloys. One of crucial issues is finding the interdependence...
The Variation of the Friction Coefficient in Pipe Connections Working Under Static and Dynamic Loads
Galling Time Dependent Friction Coefficient Lubrication
2009/10/14
The friction coecient and the galling process in metal to metal parts depend on many variables such as normal load, lubricant, roughness and design of the friction surfaces. Since developing a mathem...
Performance Comparison of Single-Stage and Cascade Refrigeration Systems Using R134a as the Working Fluid
Refrigeration Cascade system Single-stage system Coecient of performance R134a
2009/10/10
This study presents an experimental comparison of single-stage and cascade vapour-compression refrigeration systems using R134a as the refrigerant. The experimental plants employ a vapour-compression ...
