Five types of ductile cast irons (DCIs) were fabricated by crystallizers with different inner diameters, as well five austempered (ADIs) after the same isothermal quenching process. The effects amount, diameter, and morphology graphite on mechanical properties DCI ADI effect original as-cast microstructure austempering studied. microstructures characterized optical microscopy, scanning electron...

Batch crystallization is an important chemical unit operation. So, large numbers of published works were focused on batch modelization, simulation, optimization, control and parameter estimation. In this work, optimization made with the objective to obtain optimal cooling temperature strategy a crystallizer realized in our laboratory. The potassium hydrogenotartarate (cream tartar) subject stud...
