It may not be safe to get the first portion to calculate Youngs moduslus, there can be some distortion in the first part due to test machines internal dynamics. First be sure that graph is free from that.

Austensite to Martensite transformation is time independent, because its a diffusionless transformation. It only depends on temperature. If the temperature of quenching medium is not low enough, i.e. if its not lower than martensite finish temperature, complete transition will not occur...

Hi guys, its seems you have some problems about materials. First of all I do not know the temperature range at which the nozzle operate but guess its 500 - 900 C, than creep will be a major problem and materials strengths at elevated temperatures decreases dramatically. Thus using a thin...
