Age hardening- general question.

[xxguitarist]

I won't lie to all of you- this knowledge will not be directly applied to knife making, but is relevant regardless, and may assist me at some point in the future with treating metals.

Given an alloy of 10%B in A (materials not given)
the alpha -> alpha +beta solvus temp is 475 degrees C
the alpha-> alpha+ liquid solidus temp is 525 degrees C

From my knowledge the temperature required to age harden would be somewhere between 475 and 525, correct?

How can the time required to age harden be found?

Also, how does one determine the maximum service temperature? is it simply below 475 deg?

Just search on google ,we age harden aircraft alloy all the time some have a set temp otheres must be heated up then ramped down most take about 8 to 10 hours.

so, this isn't adequate information to find the time, correct?
