Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty Of Engineering - Department Of Metallurgical Engineering Summary: The aim of this study is to investigate the influence of the cooling rates on the transformation behavior of a duplex stainless steel deposited weld metal , subjected to heat treatmnets in the temperature different aging timesCooling rates (air - cooling , furnace cooling , and water quenching) followed all heat treatmentsThe effect of aging time on the ferrite content , and hardness value of the weld metal samples , for these cooling rates , and aging temperatures were evaluatedThe ferrite content decreased and hardness value increased by increasing aging timeThe microstructure of the weld metal in both as welded and isothermally heat - treated conditions has been investigated using optical microscopy , and X - ray diffraction techniques
