Mar 21, 2024 · WebJul 1, 2014 · The strain-rate hardening exponent (m-value) can present some challenges for stamping aluminum. As forming speed increases, some alloys increase in strength (m=+), some remain unchanged (m=0) and some decrease in strength (m=─). The m-value becomes important when a deformation (strain) gradient begins to form in one location.
