I'm a Hobbyist and want to Build my own axial-flow jet engine,can I use steel as the Turbine blades instead of Titanium which I can't get easily?? What about the other parts I can use for...?!
Jet gasoline definitely does get warm sufficient to soften the engines (the cores of that are created from titanium alloy, not steel). in actuality, jet engines could be in particular designed as a fashion to not soften below popular working situations. As for the engines vaporizing it incredibly is extremely not likely. They probable have been pulverized via the impact forces and the debris then melted interior the hearth.
You could but you will have to run lower pressures and speed and thus lower power output. You should do some research the Me 262 the Nazi's built. I don;t know but I think they used steel. That's why the engine had to be serviced every few hours of flight.
You can use steel but alloyed with a big percent of Mn and Cr. Titanium is very good but unfortunately it is expensive. On engines and Turbine blades it is indicate to use High Alloy metals that are resistant to fluage.
Yes you can use steel but you will want to use super alloys like hastaloy and inconel. These withstand the heat in the combustion areas. These are the actual materials used in these stages. If you only want your engine to have a service life of a few hours a conventional hot work steel like H-13 will probably be OK Blades are investment cast in foundries that carefully control the rate of cooling to create a very uniform grain structure
