However, welding of A2 tool steels are not much preferred due to the risk of crack formation. The following guidelines can be followed during the welding of A2 steels: A. Welding in order to harden the soft annealed A2 tool steel Heat to austenitizing temperature Cool to approx. 500°C...

Modern steels often recommended are the H series, O1, A2 and D2. heattreating: Tempering is one stage of heattreating. The sequence for most steels is: Normalize (or anneal depending on the steel) Harden (heat to the A3 point and quench) Temper (heat to lower brittleness and ...
where A1, B1, k0, CA, m1, CSS, m2, A2, n, Cr, Q, m3, γ0, m4, A3, Cp and m5 are material constants. Equation 11.11 describes the evolution of creep strain. The creep rate is not only a function of the stress σ and the dislocation density ρ¯, but also a function of ...
A sheet steel blank is heated to the austenite range and formed in a cooled tool pair that rapidly cools the formed product until the product's temperature drops somewhat below the temperature Ms for the start of the formation of martensite. The cooling is rapidly interrupted and the product'...
[169] also suggested that the solidification path of “Liquid → High-temperature solid solution (A2) → Ordering (B2 [dendrites]) → Eutectoid decomposition (α + B2) → Spinodal decomposition (α1 + α2 + B2) → Annealing (σ + B2)” occurred during MAM and post-annealing treatment ...
