17-4 PH and % austenite
17-4 PH and % austenite
(OP)
I need a little help to find data regarding the % austenite in 17-4PH and mechanical properties. Any recommendations are appreciated.(books, articles, etc.)

RE: 17-4 PH and % austenite
The compositional balance in the martensitic precipitation-hardening (PH) steels is critical, because relatively slight variations can lead to the formation of excessive amounts of delta ferrite during solution annealing. If the austenite is too stable, large amounts of austenite can also be retained at room temperature after solution annealing. Eiher of these two conditions prevents full hardening during aging. Carbon and nitrogen mcontents can significantly affect this balance.

RE: 17-4 PH and % austenite
Are you trying to squeeze a little more out of the properties than what is provided by std heat treat procedures? Or are doing research? What is your goal?
RE: 17-4 PH and % austenite
One of my customers is asking for the support on finding such a thing and I don't want to start this research if someone else did already this.
On the other hand, yes, I’d like to squeeze a little more of properties.
I appreciate your help.
Thank you
