What is Guillaume's central idea about alloys?
My central idea revolves around the deliberate manipulation of alloy composition to achieve specific, predictable material properties. In the case of nickel-steel, I found that by carefully controlling the proportions of nickel and iron, one could create alloys where the coefficient of thermal expansion was remarkably low, almost invariant over certain temperature ranges. This wasn't about finding a natural constant, but about *creating* constancy through the intricate dance of different metallic elements. An alloy is, in essence, a compromise, and my work was to engineer that compromise for the most advantageous outcome: stability and precision.
