When you make the AspectRatio small, make the ImageSize large.  

Or you can use an inset of the magnified region:

f[x_] := (x-0.5)(x-.65)(x-.675)(x-.7)(x-.725)(x-.75)(x-1);

Plot[f[x],{x,.5,1},
    Epilog->{Rectangle[{.5, -2*^-5}, {.8, -3*^-6},
          Plot[10^9*f[x],{x,.63,.77},
            AxesLabel->{None,"*10^-9"},
            DisplayFunction->Identity]]},
    ImageSize->450];

<< I have a function I want to Plot between 0.5 and 1.0 with a "stretched

of its domain.

I tried to find a Plot option which allows the x-axis to stretch
horizontally across the screen.  I experimented with AspectRatio ->
10, and found I could do y-axis (Range) stretch with no problem.  But
when I tried AspectRatio -> 0.1, the y-axis collapsed, and the x-axis
did not stretch at all.

I'm stumped.  I can't find an x-axis stretching option that produces
more on-screen horizontal plot details.

Does anyone know a way to stretch the x-axis in Mathematica Plots?
