What are the properties of a supercritical fluid? A supercritical fluid is a substance with both gas-and liquid-like properties. It is gas-like in that it is a compressible fluid that fills its container, and is liquid-like in that it has comparable densities (0.1–1 g ml-1) and solvating power. What are supercritical fluids used for? Carbon […]
Why Cementite is hard and brittle?
Why Cementite is hard and brittle? The ferrite is soft and ductile, whereas the cementite is hard and brittle. The steel has an increased mechanical strength because of both the presence of the two phases and because of their pearlite microstructure, however this comes at the cost of reduced ductility. Is Cementite a phase? Cementite, […]

What are the processes in an ideal Otto combustion cycle?
What are the processes in an ideal Otto combustion cycle? The Otto cycle consists of isentropic compression, heat addition at constant volume, isentropic expansion, and rejection of heat at constant volume. How does air cycle occur? How does air cycle work? Air cycle refrigeration works on the reverse Brayton or Joule cycle. Air is compressed […]
What is stress concentration What are the causes of stress concentration?
What is stress concentration What are the causes of stress concentration? Stress concentrations occur when there are irregularities in the geometry or material of a structural component that cause an interruption to the flow of stress. This arises from such details as holes, grooves, notches and fillets. Stress concentrations may also occur from accidental damage […]
