“…The deformation mechanism can be inferred according to the magnitude of the apparent stress index n , where n values of 1, 3, 5, 7, and 8 represent the stable structure model of the grain boundary diffusion control, dislocation viscous slip control, lattice self‐diffusion‐induced high‐temperature climb control, bulk diffusion‐induced low‐temperature climb process, and lattice self‐diffusion control, respectively. [ 23–25 ] The apparent stress index of the 2Cr12Ni4Mo3VNbN steel was n = 5.842, which is between 5 and 7. Together with the thermal deformation activation energy, this indicates that the main deformation mechanism is intragranular dislocation climbing.…”

The hot deformation behavior and microstructure evolution of a recently developed 2Cr12Ni4Mo3VNbN martensitic stainless steel are examined through hot compression tests conducted within the temperature range of 900–1200 °C and the strain rate range of 0.01–10 s−1. The constitutive equation and processing maps corresponding to hot deformation are established. The activation energy for hot deformation of 2Cr12Ni4Mo3VNbN steel is determined to be ≈457491.77 J mol−1. Simultaneously, the microstructure evolution during hot deformation is studied. Based on the processing maps and microstructure evolution analysis, it is concluded that the optimal windows for hot processing are within the temperature range of 1106–1150 °C and the strain rate range of 0.01–2.7 s−1, as well as at 1200 °C within the strain rate range of 1–2.7 s−1, exhibiting a power dissipation efficiency of 0.32. As the temperature increases and the strain rate decreases, the degree of dynamic recrystallization escalates.

The quest for sustainability in feed production industries and crushing machines in agricultural sectors that are more efficient have introduced the use of proper material for hammer material. Around the world, the manufacture of feed from animal waste is expanding quickly, and crushing equipment is now essential to enabling reliability. The issue of early failure of the crushing machine’s main components, however, is a challenge for the feed industries and has a direct impact on the machine’s maintenance, dependability, and running costs. A significant number of technical components have been created during the past decade for industrial applications employing novel materials and cutting-edge technologies through the development of carburisation. As a result, this review offers a concise summary of the most recent analysis of tribological issues related to crushing hammers made of low and medium-carbon steels. Recent studies on innovative crushing material design, improvement in hammer surface engineering, use of case-hardened hammers with a focus on material selection, crushing machine design optimisation, and failure mode analysis are included in the study. Additionally, it will intricate on the heat treatment technology’s present constraints and its future opportunities.
