(a) Distribution of the metallurgical variable 𝑧 in the bar at time 𝑡=9×10⁻²s (dotted line), 𝑡=9.5×10⁻²s (dashed line), and 𝑡=𝑡₀=10⁻¹s (solid line) where 𝜎_𝑦(𝑇,𝐪)=𝜎¹_𝑦. (b) Distribution of the temperature in the bar at time 𝑡=9×10⁻²s (dotted line), 𝑡=9.5×10⁻²s (dashed line), and 𝑡=𝑡₀=10⁻¹s (solid line) where 𝜎_𝑦(𝑇,𝐪)=𝜎¹_𝑦.
