The austenite phase is a high temperature solid phase which only exists in equilibrium at temperatures above 727 degrees Celcius.
The material is then isothermally cooled at a temperature of approximately 400 degrees Celcius.[6] , in order to allow the austenite to form a banitic ferrite phase. (I think there is a period where you meant just to put a comma.)
TRIP steel does not face any of these difficulties.
Constructive Criticism First off, I would just like to say that everything written so far in this paper is very well explained and completely understandable. The article is also well laid with references and links present everywhere confusion could arise.
With that in mind, below are a few suggests you could implement to make your article better.
In the Underlying Materials section, it I think it would be useful to show a phase diagram of the heating and cooling of TRIP steel to better illustrate your point. Additionally, a few grain microstructure photos could be helpful in conveying your points in the "TRIP" effect section or just in the Underlying Materials section in general.
In the Identification section, I would suggest adding a little more than two sentences. I don't know if there is more to add but if there isn't I think you should consider including it in another section as putting it in its own section seems silly since it is so short.
In the Advantageous Material Properties section you talk about ultimate tensile strength and yield strength, so I think you should consider adding diagrams to that section to better illustrate your point.
I think you have done a fair job at describing what "TRIP" steel is and how it is made but there is some obvious work that must be done on the Economics estimates sections.

for the fuel efficiency - you described what needs to be done -- now do it![edit source]
