Stainless steels that harden by subcritical temperature aging process
The ocean is larger than a lake. Therefore, being larger it can absorb more heat. That is why a lower temperature is needed to freeze it.
To increase the melting point of aluminium, (and treating this as a philosophical question), then hardening the 'crystal matrix' may be one approach. Surface hardening by work hardening, or perhaps by inserting nitrogen ions into the surface as is used in metal(ferrous) hardening.
Dissolved salts in water contribute to a decrease of the freezing point.
sclerite
the temperature needs to be 60c a nickel catalyst should be used to speed up the reaction
age hardening is the result of precipitation of the one or more compounds whose solubility decreases with decrease temperature from a solid solution. For each alloy susceptible to aging, there is a unique range of time-temperature combinations to which it will respond to age hardening.
Stainless steels that harden by subcritical temperature aging process
The main requirement for an alloy system to respond to age-hardening is a significant decrease in solid solubility of one or more of the alloying elements with decreasing temperature.
Hardening sunflower oil makes it a solid at room temperature which is suitable for spreading so I don't think that it makes much difference. I could be wrong though. Sorry!

One of the effects of hydrogenating vegetable oil is to raise the melting temperature, making it a solid instead of a liquid at room temperature.
mostly is the hardening done by induction hardening machine, I know also manufactures that do this using the flame hardening method.
in my opinion surface hardening is applied only on the surface while the true hardening is applied in the whole part of the metal....
No...Gelatin is thickening/hardening agent created by boiling animal (bovine) bones and isn't needed in soft drinks.
what the was on tooth hardening day?
Arteriosclerosis is hardening of the arteries.
