In the present work, the pyrolysis of acetylene was studied under steel vacuum carburizing conditions in a tubular flow reactor. The pyrolysis temperature ranged from 650 degrees C to 1050 degrees C. The partial pressure of acetylene in the feed mixture was 10 and 20 mbar, respectively, while the rest of the mixture consisted of nitrogen. The total pressure of the mixture was 1.6 bar. A kinetic...

Carbon case hardening, through natural evolution, commercialism, and economics, has become a process for which the possible number of variables is so large that it is hardly likely that any two companies will process exactly the same. There will always be some difference in choice of materials, equipment, or technique, and there will often be differences in the quality of the product. There may...

Pack carburizing is a method of surface hardening steel which carried out by diffusing carbon into the material where initially solid. This study aims to determine effect pack treatment on microstructure and hardness AISI 1010 steel. The was then cooled slowly in oven temperatur 150oC followed air cooling. Single Quenching reheating temperature 870oC holding it at that for 60 minutes. done cool...
