in the present research, damage mechanisms during room temperature uniaxial tensile testing of two different modern high strength dual phase steels,dp780 and dp980, were studied. detailed microstructural characterization of the strained and sectioned samples was performed by scanning electron microscopy (sem). the results revealed that interface decohesion, especially at the triple junctions of...

Prediction of the nucleation mechanism is one of the most critical factors in the design of a crystallization system. Information about the nucleation mechanism helps to control the size, shape, size distribution, and purity of the produced crystals. When the crystallization method is used for producing nanoparticles, the nucleation mechanism should be predicted. In this study, an empirical cor...

Background and Objectives: Freezing under statically electric fields is one of the novel freezing methods to improve the quality of frozen products by controlling the nucleation process. The objective of this study was to investigate effects of freezing under electrostatic fields on the freezing parameters and microstructures of frozen button mushrooms. Materials and Methods: Mushroom samples w...

Hyd rot hermal synthes is of faujasite type zeolite in a short crysta llizat ion period could be performed by preparing a fresh aqueous nucleation solution mixed with an aluminosilicalc gel into a teflon tube placed in thc stainless-steel microautoclave. Effects of source of s ilica, sodium silicate, and colloidal silica and also aging of nucleation solution were examined 10 prepare a hig...
