    Annealed 1018 Steel - Investigating Darker Regions

    Sure, dark structure is Perlite. Carbon fraction is given in alloy specification 1018 \rightarrow 0.18% Carbon And ... Annealing Treatment ( Total Annealing) may result in perlite + ferrite. It's shown in your micrograph Dark - perlite Bright - Ferrite

    SAE 1055 properties after HEat treatment

    Predict Mechanical properties based on hardness tests may be useful in some cases but results could be far from reality. I suggest you check out www.matweb.com its a great materials properties library

    Producing Martensite & Bainite in Carbon Steel

    I guess the better way to preditc a microstructure result from a heat treatment is looking for the TTT diagram for your alloy. From the cooling rate you may sketch the curve and analise the initial and final points in the diagram curves for phase transformation. An example of TTT diagram...

    How Can I Calculate Thrust as an Airspeed Function for Propellers?

    Does anybody here knows how can i calculate (or plot) the Thrust as an airspeed function? I guess it'd be something related with Pitch, Diameter, HP, air density... Or... a way to calculate RPM as a pitch, diameter and power function? thanks!
