The ferritic ductile iron (FCD400) is widely used as industrial material. As regards to its high temperature application, fatigue at elevated temperature, and advanced mechanical properties has been investigated and clarified. In low cycle fatigue (LCF), the S-N curve is presented by the relation of plastic strain to the number of cycles as fatigue life, which can be predicted by the Manson-Cof...

In the present work, three heats of Si-Mo-Cr ductile cast iron with varying amounts major alloying elements are produced. The effect microstructural features on microhardness, tensile strength and ductility is studied. Increasing nodule count decreases pearlite-ferrite ratio, which results in a decrease but an increase percentage elongation. spherical plays significant role arresting crack reor...

An investigation of the friction and sliding wear of gray cast iron against chromium plated cast irons was carried out on a newly constructed reciprocating friction and wear tester. The tests were the first to be done on the test rig under dry conditions and at the speed of 170 cm/min, and variable loads of 20-260 N for a duration of 15 min. to 3 hours. The gray cast iron surfaces worn by a pro...

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...

In the present investigation, effect of varying carbon content on impact energy ductile cast iron was studied. Three groups austenitic (A), (B) and (C) were prepared for Charpy tests. The equivalent percent (% CE) group (A) ranged from 3.51 to 5.04 variable element carbon, whereas % CE is 3.86 4.64 silicon, 3.79 4.80 nickel. Results show that there an inverse proportional relation between absor...
