I use ductile iron material because it has mechanical properties that are suitable for making components that require a hard surface so that they are to wear recistance. (accordance to ASTM A 536) For example bearings, rail roads, gears and others....

To determine the mechanical properties of the ductile iron used, I don no get the test. But I only used Vickers hardness and micrography using an optical microscope.

In terms of tensile stress, thoughness and elongation, I did not test because the Inoculand process has responded based on the nodularization structure which is based on the analysis of the microstructure at the center zone of the Y-Block specimen that I used. And also the composition test has responded.

My research focuses on surface layar analysis, there are (microhardness and the percentage of element deposition).

Thank you......

Dear Dr. Guterres,

Thank you for your response.

About standards inspection for ductile cast iron, I'm still looking for it, but what the foundry industry usually uses is

1. inspection

performed when the new casting is unloaded from the mold,

2. done after the castings are cleaned

with a shot blast machine, and

3. when

the castings have been machined.

Thanks🙏

It would be appreciated if you could inform me when you find any related standard.

Thanks again🙏
