Research Areas:

Solidification, continuous casting, strip casting and shaped casting. Thermodynamics and kinetics of precipitation of microalloyed steel: quantitative modelling of steel processing aimed at nicrostructural optimization for sheet, plate and bar products. Microstructural design for improved machinability.

Current Research Projects:

  1. Quantitative modelling of solidification, precipitation and recrystallization analyses in microalloyed line pipe steel
  2. Thermo kinetic analyses of precipitation in microalloyed interstitial free sheet steel
  3. Microstructural engineering of calcium treated microalloyed medium carbon steel for improved machinability;
  4. Graphite morphology control in cast iron
  5. Micromechanisms of tool wear and chip formation during high speed machining of metals.

Current Collaborative Research Projects:
