I am designing an assembly which will incorporate a Maxwell Kinematic mount (3 balls, 3 V-grooves). The balls will be sapphire and the V-grooves some type of hardened SST (440C perhaps). The basic Hertzian spherical indentation equations use the Elastic modulus and Poisson's ratio to calculate the modified Elastic modulus. Does heat treating change the elastic modulus of a material? My local heat treater told me it does not, "modulus is a function of chemistry". Is this correct? Perhaps locally (contact) but not globally (deflection of a sample in tension or bending)???
