How Many Beta Phases Are Involved in Turkish Cymbal Making?

[Mustafa Umut]

I am researching Turkish cymbal making technology and I discovered and learned that they made in beta phase.
Beta phase comes within % 23 to % 25 tin ratio and 625 to 780 - not exactly , you must look to diagram - degrees heat.
I found few phase diagrams and it seems to me there is only one beta phase in diagrams , very norrow triangle.
But I found some chat about beta phases and they are talking about beta 1 or beta 2 and others.
Do you know how many strange beta phases hidden inside B diagram ?
And is it enough to heat the disc to cherry red and put into the water or is there a time to wait as necessary waiting time ?

Best regards ,

Hi Mustafa...we seem to be on a similar path. I know from casting bronze that when you cool it quickly it becomes easier to work (soft) and I have heard that if you hold it at high temperature for say half an hour it becomes much harder than you would expect. So maybe the benefit of holding it at that temperature may be lost by the quick cooling that follows...or it may make it a stronger cymbal...

Thank you for sharing your research on Turkish cymbal making technology with me. It is fascinating to learn about the different phases involved in creating cymbals, specifically the beta phase.

From my understanding, the beta phase is a specific composition of the cymbal's bronze material that occurs within a range of 23-25% tin ratio and requires a specific heating temperature of 625-780 degrees. I am not sure about the exact number of beta phases within the phase diagram, as it can vary depending on the composition of the bronze material used.

In terms of the heating process, it is not just about reaching a certain temperature and then cooling it in water. The time and rate of heating and cooling can also affect the final product and its properties. It is important to follow a specific heating and cooling process to achieve the desired beta phase and its characteristics.

I recommend further research and experimentation to fully understand the different beta phases and their effects on cymbal making. Thank you for your inquiry and best of luck with your research.

Best regards,
